Nice quick informative info on the 660 carb basics. I like the way you delivered the information. Keep up the great videos. I'm gonna take a second look at my seals😘
Well said... Definitely helped me see where im lacking understanding.. Appreciate the quick to the point vid. No fancy intro, just great detailed info.. Doc
floats arent lifting up enough to stop flow. but if you set them too much you wony get enough gas. i believe 13 mm is the about measurement for the floats. cut a piece of cardboard at 13 mm. turn carb in its back where the floats rest by itself. with bowls of it should be 13 mm from carb rim(part where bowl meets carb) to the top of float. do not push with finger. it will make adjustment off
I only used the sealant until my new seals came in. Before putting new seals in i suggest cleaning inside of the bowls again. Leaking through tube on bottom of carb is causr float adjustments are off. Float is sitting too high. Adjust it down little by little until its not leaking. If adjusted down too much the carb wont get enough fuel.
Okay so I had my ATV shipped in parts to where I am now (Pakistan) it’s a euro model. Since putting it back together I’ve had a few issues (I’ve gone by the manual guidebook. . Carb problem. I cleaned the filter out and doused it with engine oil to make it stick and I blowed and pumped air through the carb on taking the air filter out and little little bits of silver would come out and be visible in the petrol. Didn’t work! Overflow pipes are throwing out alot of fuel and to basically stop that and prevent it I’m having to leave the fuel on half or less than half on like literally a little up from off. Now I need to open up the carb and clean it n check the float levels. Can anybody guide me or give me any advice as where I am now there isn’t a mechanic or anyone who specialises in these machines so I’m gonna have to go about it myself. . I have a tooth on the front sprocket broken, which I think may have something to do with the bike not going in neural when switched on. My question is if I were to get it repaired as it’s only 1 tooth on the cog would it be okay or would it be best to replace the part as a whole (remember I’m in Pakistan there’s no part market for this and will be a long wait in the post) so could it be possible to repair that sprocket cog. The bike does go in neutral but only when switched off does not happen when started. . Choke problem. The chokes basically still too high or fast even at the lowest point as in the bike still warms up even when it doesn’t need to and then gradually heats to a point where the bike turns off and the cooling fan comes on. . Any help would be very much appreciated! Thanks for reading, i will take pictures and upload in where I could get any assistance. .
Any idea why my raptor 660 coughs and sputters and won't even move when I put it in reverse but it runs and drives perfect in all the The forward gears
Insane job!! Question please my raptor 660 2001 Does not whant to idle!! Have to hold trottle And the jets they mixed them up where i tryed to get it fix!!!!😢 Thanks
Mine idles fine but won’t take throttle. It stumbles and backfires when you throttle. It came without a plate over the throttle on carb and no air filter.. I installed both
typically u should rejet with bigger exhaust. try running no filter. and also if your floats dont open fast enough it wont allow enough fuel to get in the carbs
Both carbs are in use at all times one is not high and one low one just has extra jet for starting it has 2 cylinders so both pistons would have to get fuel constantly one for each piston. Both carbs have a main jet and pilot jets
Float height will over flow carbs if not done right. Gas will pout out. If not enough it will not stay running. With the back firing re adjust the carbs to my settings. Make sure theres no exhaust leaks. That will cause a back fire too.
rejet kits are real cheap. and make sure air fuel ratio is right. it will change as you modify exhaust. remember...bigget exhaust, more air excapes. so youve gotta allow for more air to enter. air makes a world of difference in combustion. so youve gotta adjust fuel with it. exhaust leaks and intake leaks also can cause issues
Hey my raptor 660r is over heats when cruising on the trials with my kids but if I gun it. It will not over heat. I'm using dynojet 144 for the low and 146 for the high. For the needles it's at number 4.
i have a 01 660 full yosh pipe 686 big bore 10:1 ordered the 6 sigma jet kit came with 27.5 pilot jets and 180/185/190 main jets put 180 left 185 right idle to around 3/4 throttle fine wot real choppy keeps cutting out kinda is the the jets to large or small also i have started working my way down dont seem to make a difference someone help
I am having trouble getting my raptor 660 to start I got hosed buying it on Craigslist so I replace the whole top end and everything else including wiring except the gears in crankcase it started first shot but after I turned it off it won’t start again any ideas
Hey I just rebuilt a raptor 660r 01 including the carbs , I changed the compression to 11:1 with a high compression piston an the set carb to manual specifications and when I start it i can't get it too accelerate it just sputters , any suggestions?
pull the carbs. check the jets and make sure the floats are allowing enough fuel to the bowl. if too little fuel it will lean out and back fire. but it will still idle fine
HELP!!! I have a 2003 Yamaha 660R Raptor that I just took for a ride down the road with my son nice and easy we'll say and when I pulled up to the garage when done my airbox was full of oil which leaked out the bottom of the airbox everywhere do you know by chance why it did this? I am at a loss?
i have a 2008 raptor 660 it won't past half throttle it starts to bogg out carbs are clean but my shop dude says since i took the stock exhaust off an put a aftermarket i need to re-jet the bike ...what you thank ......aftermarket hmf pipe an i used my E-47 exhaust an it still dose not full throttle
I have a 2002 raptor 660r that I just got guy said that it would be hard to start and would die and I got it and it will turn over great but will not start I’ve tried stater fluid but still doesn’t start
I have an 02 660 new carbs aftermarket it runs fine starts right up you can give it full throttle wants give it full throttle again and it’ll stall out but if you stay in the throttle it will stay running wide-open what’s my problem new jets
If you the wrong way to fix that. Tape half of the airbox inlet off. I know I'm an idiot , but mine was doing the same thing . Even brought it into the dealer . They wanted me to buy new carbs. I taped the inlet and it runs like brand new.
My quad when gets warm d up has a low rpm sputter when I first get on it but then comes out of it. At higher rpm. .I have pipe stage 2 dyno jet k n. Pro Flo kit modded box.
yes i have a 03 raptor 660 as well an when i start it an rev it ut back fires then when i get to 3rd gear it starts to backfire and kind of pull back is that the same reason in this video I would have to clean the carbs
Hey man I’ve got my carbs set on 3 turns on both it cranks up perfect sets idles perfect give it gas does great it revs up great wheni take off in first it’s good but when I hit 2nd ,3rd etc to open her up it wants to go but then it will like bog down on me and won’t accelerate to wide open I’ve also got the needles both on 4 notches what do you think I should do… I was thinking maybe going down another notch on both needles to hopefully it will give me more gas when I try to open it up what yu think
Hi thank you for a very informative video. The question " I bought a new carb (aftermarket) and had a young adult put it on, weel , three months later I just said give it back and now we cant get it started. I inherited this machine from my husband and just wanted to ride it for summer than sell. was suppose to be easy to get it running after a couple years sitting ran, started up before he took it abut leaked gas from carb. I thought it would be better to purchase a new carb rather than have the kid rebuild the carb. Carb was about 55. for new one I thought it would save some money since the kid was thinking it was a racing bike and getting very expensive filters etc, so was I an idiot for buying new? so how to I start it and I haven't rode in about 12 years, had a 250 blaster with kick start . I believe this has a electric start but my nephew tried to start it and it wouldn't so I am assuming something with carb. do you have any tips
I have a 2003 raptor 660r, i have to hold the electric start for like 30 seconds for it to start and when it does it feels like it doesn't ride good. I can slightly give it throttle but if I don't full throttle it almost the whole time it tries to die like its flooding or something... Its also shooting out some blackish smoke, nothing crazy yet but something noticeable. Hoping my air/fuel screw just needs adjusted or jets need swapped. I have a 2 brothers exauhst and that's about it, what should I do?
I have a 2003 raptor 600 with K&N air filter and after market exhaust, what main jets should I run? What size piolts? And that third one on the left how big should that jet be? And the needle clip piston? Also still 2 and 3 turns out on air/fuel? Please lmk thanks
Fivepoint OH I have an 02 raptor 660 and it rides fine with choke off but you gotta keep giving it some gas. But to let it sit and idle, i gotta put the choke on. If the choke is off and you let off the throttle completely, it will die. What could be the issue
Ey man good video. I am working on a 03 660r lots of extras. Was built for racing on sand dunes. Guy I bought it from thought it was too much. I think itd be perfect if damn carb wasent leaking. Found all kinds of external seals a miss. If small tubes on bottom of carb are leaking that would mean an internal clog or floats off correct? Sure I will have to open it b4 putting it back on my bike. Also how long would you expect the sealant you used to hold? You said temporary. And was that you used just a rtv?
Got a 01 raptor 660. Just rebuilt the carb and it'll start up just fine but can't give very much throttle and it'll start bogging out and back firing. I noticed in your video you had your mixture screws at 2 & 2.5 turns. I put mine back in the same way they were when I took it apart and they were 3 & 3.5 turns. You think adjusting those would help? Also I didn't know about float height I'm assuming that would make a difference too..
Hey bro your video is amazing. The quad launches perfect but when I get passed half throttle it lacks power and kinda sputters what do you suggest I do next ??
Hi Cody, thanks for the 660 video. What advice can you give me for adjusting for altitude? I'm starting at 6,000' which is about where the bike is jetted for now. I'll be summitting 8,500 to 10,000' then returning to 6,000'. What lets should I carry with me for the trip? i'm afraid I hit 8,500' and there wont be alot of power....Thanks for the help.
My carb idle just fine but I can't rev it, if I try slowly it won't rev high and backfires, if try quickly in just sucks in air and almost stalls. Any idea? 155 both sides, 2 turns, 2nd clips position for needles.
Hey great video ! I have a question bout an 01 raptor 660 ! Its tends to accelerate when idling and then it calms down on its own! I have cleaned all the jets and everything is sealed what else should I check ? It also has an aftermarket exhaust !
I have a questions about a 01 Raptor 660, the float leaks fuel and when i start it the idle is really high then dies like it's running lean. What should I do?
I have a 2001 fully stock raptor660r and I wanted to install an HMF high performance exhaust and they are telling me that I have to buy a jet kit for it too. Can I just adjust the two screws on each carb, like on ur video, the screws on ur video that are across from the throttle adjuster? Or do I have to install the jet kit? two full turns on the carb closest to the adjuster and one full turn to the other carb would maybe do it instead? and do I turn the screws clockwise or counter? TY for ur help man, I bought the quad recently but I've really become attached to it and want to hook it up. with that being said would you recommend that I do something before I change the exhaust? sorry I have so many questions, I could really tell by ur video that not only do you know ur stuff but you enjoy the quads like I have started to. Basically, what would you do first, 2nd etc. to this raptor 660r if it was yours? Damon
Its gonna be time consuming but the floats are out of adjustment. You have to bend the tab just right.with the carb flipped it rests the floats closed. It should be about13 mm from the housing to the rim of the float.
wow I've been looking for this exact content have a problem with my Raptor good on idle and putting around and up in the top of the throttle it's good but in the middle it sputters I've been messing with my quad for the past 2 weeks everyday spent I don't even know how much money on little stupid whatever's put a new choke assembly on cuz it was going bad but bought new float valve kits new Jets two and four steps down that didn't fix shit I'm back to the Jets better supposed to go to it I got a big bore stage 2 cam aftermarket exhaust what should I try next?
I have a 2001 660 got it carbs where clogged from setting a year cleaned new o rings on jets new gasket seals every where but no matter what it's idling extremely high and want change
rebuilt my carb the other day set a/f screw to 2 and 3 quad tries to start just won't start any ideas of what to adjust or check as long as I push the throttle it'll pick up a little bit and almost starts but won't please help any suggestions to try I'm open to
my needle valve in the right carb keeps coming apart spring won't stay on the needle and plunger should I just buy a rebuild kit? has brand new jets already got it in on a trade
I picked up a old Yamaha twin 4 stroke quad with no info at all , is the 660 the only twin 4 stroke out there? It could be just a hack mod I suspect look like the pipes are diy weld and are down piped 2into1 never seen any stock like it ?
hello good afternoon I wanted to see if I could help what happens esque I have a raptor 660 and have the problem that the carburetor metira gasoline and apart when I bring so Allo long run the bike me off as if he were gasoline Aque Accelero punishment immediately if not you are off if you loose enpiesa atronar mufflers and leaves the fire and if not it goes Accelero
Hey Man, I got a a question I wanted to ask to see if you could help. My buddy's Raptor starts to sputter when you try to get on the throttle. It wnt even go half throttle distance before it starts to pop and afterfire out of the exhaust. What do you think I should do? Back out the micture screws for more fuel?
hey Cody, i have a 2003 660 raptor and the left manifold (if u see it when you got on the atv) was drilled and my bike does not start, help me please! thanks
hey ii had a question for you, i have a yamaha raptor 2004 660. and when i turn it on it stays in but when i give it gas it makes a weird sound sounds like if it was choking on to much gas any idea of what that could be/
@Cody Sheets Should both the flaps open at the same time or do they work one after the other? And also, should high rev side open all the way up flat, (90°turn) or only about 3/4 of the way? I'm excited to ride. I gotta get the carb right and I'm having starting problems too.
Nice quick informative info on the 660 carb basics. I like the way you delivered the information. Keep up the great videos. I'm gonna take a second look at my seals😘
dude u rock .. I learned more from this vid than I did from the factory service book .. big facts
Man I have come back to your video like six times thank you so much
Bro thank you I just bought one and your the first video that got it running I was about to sit it on fire
This video is exactly what I needed. You were clear and informative. Keep it up my friend
That is great info. I’ve been having problems with these new carburetors I put on mine. I don’t think the air and the fuel is set, right
Well said... Definitely helped me see where im lacking understanding.. Appreciate the quick to the point vid. No fancy intro, just great detailed info..

Carb problem. I cleaned the filter out and doused it with engine oil to make it stick and I blowed and pumped air through the carb on taking the air filter out and little little bits of silver would come out and be visible in the petrol.

Gracias thanks for your patience and exelent explain
Thanks brosive this really helped me out allot
Insane job!!
Question please my raptor 660 2001
Does not whant to idle!! Have to hold trottle
And the jets they mixed them up where i tryed to get it fix!!!!😢
Thanks

Fivepoint OH I have a 2001 raptor 660 I have no spark. I have already replaced the ignition coil. Do u know what else could cause no spark.
So when you adjust a carb do you mean screw it all the way in then screw out 2 times
Yea. Usually 2.5 time. U screw it in till stops don't do it right not hard just slow till stops it self. The. U unscrew it 2 to 2.5 times out
This guy knows what's up
Hey my raptor 660r is over heats when cruising on the trials with my kids but if I gun it. It will not over heat. I'm using dynojet 144 for the low and 146 for the high. For the needles it's at number 4.
i have a 01 660 full yosh pipe 686 big bore 10:1 ordered the 6 sigma jet kit came with 27.5 pilot jets and 180/185/190 main jets put 180 left 185 right idle to around 3/4 throttle fine wot real choppy keeps cutting out kinda is the the jets to large or small also i have started working my way down dont seem to make a difference someone help
Dustin Jackson did you fix this I have same the problem
I am having trouble getting my raptor 660 to start I got hosed buying it on Craigslist so I replace the whole top end and everything else including wiring except the gears in crankcase it started first shot but after I turned it off it won’t start again any ideas
This man knows
Hey I just rebuilt a raptor 660r 01 including the carbs , I changed the compression to 11:1 with a high compression piston an the set carb to manual specifications and when I start it i can't get it too accelerate it just sputters , any suggestions?
what if I have black smoke coming out the exhaust??? what would cause that and what would be the fix??
Got a 660 kepp back fireing put new carbs on back fires a little bit
pull the carbs. check the jets and make sure the floats are allowing enough fuel to the bowl. if too little fuel it will lean out and back fire. but it will still idle fine
So is it 2 turns out on the left and 3 on the right? Some people say 3 on the left and 2 on the right? Wich one is correct? Or wich one works best?
Have a raptor 660, I touch the throttle and it sputter horribly, I got further and it back fires
Good afternoon I have a 2005 660 raptor I cannot get a spark , get just click click when trying to start any suggestions
HELP!!! I have a 2003 Yamaha 660R Raptor that I just took for a ride down the road with my son nice and easy we'll say and when I pulled up to the garage when done my airbox was full of oil which leaked out the bottom of the airbox everywhere do you know by chance why it did this? I am at a loss?
I have a raptor 660 2003, I just can not get the carb to work. If it send it too you can you rebuild it and how much?
i have a 2008 raptor 660 it won't past half throttle it starts to bogg out carbs are clean but my shop dude says since i took the stock exhaust off an put a aftermarket i need to re-jet the bike ...what you thank ......aftermarket hmf pipe an i used my E-47 exhaust an it still dose not full throttle
Great info here. Thanks!
I have a 2002 raptor 660r that I just got guy said that it would be hard to start and would die and I got it and it will turn over great but will not start I’ve tried stater fluid but still doesn’t start
I have an 02 660 new carbs aftermarket it runs fine starts right up you can give it full throttle wants give it full throttle again and it’ll stall out but if you stay in the throttle it will stay running wide-open what’s my problem new jets
The best i seen on 660 i working on a 04 it will idle you hit the throttle it just pops backfires and dies out the crabs
If you the wrong way to fix that. Tape half of the airbox inlet off. I know I'm an idiot , but mine was doing the same thing . Even brought it into the dealer . They wanted me to buy new carbs. I taped the inlet and it runs like brand new.
Should do a video of fully cleaning n puting on n runing the bike plz n thank u
My quad when gets warm d up has a low rpm sputter when I first get on it but then comes out of it. At higher rpm. .I have pipe stage 2 dyno jet k n. Pro Flo kit modded box.
How do I get a hold of you, I feel like it might be my carb that is clogged but I would like to message you and see what you think
Great help
Hi I have a 2001 660R raptor stock. fuel mixture for both are two turns out and the other one is three turns out?
Can I ship my carb man lol u seem badass with the ATV knowledge
yes i have a 03 raptor 660 as well an when i start it an rev it ut back fires then when i get to 3rd gear it starts to backfire and kind of pull back is that the same reason in this video I would have to clean the carbs
Hey man I’ve got my carbs set on 3 turns on both it cranks up perfect sets idles perfect give it gas does great it revs up great wheni take off in first it’s good but when I hit 2nd ,3rd etc to open her up it wants to go but then it will like bog down on me and won’t accelerate to wide open I’ve also got the needles both on 4 notches what do you think I should do… I was thinking maybe going down another notch on both needles to hopefully it will give me more gas when I try to open it up what yu think
I have a 05 raptor660r and its bobs out in reverse do you knows what could be my problem
i got a question it starts up fine but when i give it gas it bogs
Yes on the vacuum slides
Hi thank you for a very informative video. The question "
I bought a new carb (aftermarket) and had a young adult put it on, weel , three months later I just said give it back and now we cant get it started. I inherited this machine from my husband and just wanted to ride it for summer than sell. was suppose to be easy to get it running after a couple years sitting ran, started up before he took it abut leaked gas from carb. I thought it would be better to purchase a new carb rather than have the kid rebuild the carb. Carb was about 55. for new one I thought it would save some money since the kid was thinking it was a racing bike and getting very expensive filters etc, so was I an idiot for buying new? so how to I start it and I haven't rode in about 12 years, had a 250 blaster with kick start . I believe this has a electric start but my nephew tried to start it and it wouldn't so I am assuming something with carb. do you have any tips
Hey I have a question what are the jets sizes ??
check exhaust leaks and intake leaks. most of the time a bad exhaust leak draws air and leans it out. more throttle more air pull. id start there
I have a 2003 raptor 660r, i have to hold the electric start for like 30 seconds for it to start and when it does it feels like it doesn't ride good. I can slightly give it throttle but if I don't full throttle it almost the whole time it tries to die like its flooding or something... Its also shooting out some blackish smoke, nothing crazy yet but something noticeable. Hoping my air/fuel screw just needs adjusted or jets need swapped. I have a 2 brothers exauhst and that's about it, what should I do?
I have a 2003 raptor 600 with K&N air filter and after market exhaust, what main jets should I run? What size piolts? And that third one on the left how big should that jet be? And the needle clip piston? Also still 2 and 3 turns out on air/fuel? Please lmk thanks
Fivepoint OH I have an 02 raptor 660 and it rides fine with choke off but you gotta keep giving it some gas. But to let it sit and idle, i gotta put the choke on. If the choke is off and you let off the throttle completely, it will die. What could be the issue
RVT on the carb bowls ?? no thats a good way to plug up ports an jets. the rubber gaskets are cheaper than a tube of rvt !!!
Ey man good video. I am working on a 03 660r lots of extras. Was built for racing on sand dunes. Guy I bought it from thought it was too much. I think itd be perfect if damn carb wasent leaking. Found all kinds of external seals a miss. If small tubes on bottom of carb are leaking that would mean an internal clog or floats off correct?

Nice video bro
I have a raptor 660 it turns over it’s got sport but it will not crank what can I do to fix it
Hey bro your video is amazing. The quad launches perfect but when I get passed half throttle it lacks power and kinda sputters what do you suggest I do next ??
Thanks for the video. Do you have any tips why 2005 Raptor 660 would have really hard star when it's cold? Do I need to clean the carb?
Hi Cody, thanks for the 660 video. What advice can you give me for adjusting for altitude? I'm starting at 6,000' which is about where the bike is jetted for now. I'll be summitting 8,500 to 10,000' then returning to 6,000'. What lets should I carry with me for the trip? i'm afraid I hit 8,500' and there wont be alot of power....Thanks for the help.
My carb idle just fine but I can't rev it, if I try slowly it won't rev high and backfires, if try quickly in just sucks in air and almost stalls. Any idea? 155 both sides, 2 turns, 2nd clips position for needles.
Hey great video ! I have a question bout an 01 raptor 660 ! Its tends to accelerate when idling and then it calms down on its own! I have cleaned all the jets and everything is sealed what else should I check ? It also has an aftermarket exhaust !
I have a questions about a 01 Raptor 660, the float leaks fuel and when i start it the idle is really high then dies like it's running lean. What should I do?
I have a 2001 fully stock raptor660r and I wanted to install an HMF high performance exhaust and they are telling me that I have to buy a jet kit for it too. Can I just adjust the two screws on each carb, like on ur video, the screws on ur video that are across from the throttle adjuster? Or do I have to install the jet kit? two full turns on the carb closest to the adjuster and one full turn to the other carb would maybe do it instead? and do I turn the screws clockwise or counter?

I have a 01 660 raptor with fmf exhaust n a pro seriers air intake im up to stage 2 jets were should i set my needles at to fine tune it
So I put 2 sickle to get me home an it doesn't want to run good it cuts out now what do I need to do to clean my carb ?
i have a raptor 660r ..when i trun my gas on its floodes my quad and then drips out on the bottom of my carburetor but only the rite side..any ideas??
Its gonna be time consuming but the floats are out of adjustment. You have to bend the tab just right.with the carb flipped it rests the floats closed. It should be about13 mm from the housing to the rim of the float.
Do u know what causes the raptor to die in idle
wow I've been looking for this exact content have a problem with my Raptor good on idle and putting around and up in the top of the throttle it's good but in the middle it sputters I've been messing with my quad for the past 2 weeks everyday spent I don't even know how much money on little stupid whatever's put a new choke assembly on cuz it was going bad but bought new float valve kits new Jets two and four steps down that didn't fix shit I'm back to the Jets better supposed to go to it I got a big bore stage 2 cam aftermarket exhaust what should I try next?
I have a 2001 660 got it carbs where clogged from setting a year cleaned new o rings on jets new gasket seals every where but no matter what it's idling extremely high and want change
Kenny Morton make sure the throttle cable is in the carb right. It slides all the way down only one way.
Cody Sheets I'll check that I notice when hitting throttle with engine off the slide never raises just a flap behind the slide is all that moves
rebuilt my carb the other day set a/f screw to 2 and 3 quad tries to start just won't start any ideas of what to adjust or check as long as I push the throttle it'll pick up a little bit and almost starts but won't please help any suggestions to try I'm open to
What rebuild kit would you recommend
How many turns have in the air
Hey bro I was cleaning my carburetor on my raptor 660 but I don't know how to adjust the fuel mixture screws can u let me know how to do that
My 660 starts fine but dies out during idle start like it's getting to much or not enough gas. What would that be
I install a new carburetor it runs but wen I push the gas it won't rev
What will happen if the floats are not set up to 13mm? What are some things that will happen to the raptor if it’s not set right?
my raptor 660 one carb is blowing air out of the high rev one and the low rev and idol is sucking do u know what that could be
my needle valve in the right carb keeps coming apart spring won't stay on the needle and plunger should I just buy a rebuild kit? has brand new jets already got it in on a trade
Hey did you put your carbs on there's sides and so the float tab just rests on the needle valve tip and measure?
I took the air box off and switched the muffler what jet should I use
How can you adjust the throttle body I seen most of your videos but have not seen any set.
I picked up a old Yamaha twin 4 stroke quad with no info at all , is the 660 the only twin 4 stroke out there? It could be just a hack mod I suspect look like the pipes are diy weld and are down piped 2into1 never seen any stock like it ?
great videl, thanks a lot

Hello I have a raptor that I'm having problems
Hey man are you still active on here
Hey Man, I got a a question I wanted to ask to see if you could help. My buddy's Raptor starts to sputter when you try to get on the throttle. It wnt even go half throttle distance before it starts to pop and afterfire out of the exhaust. What do you think I should do? Back out the micture screws for more fuel?
Alejandro Suarez did you fix it mine does the same thing? Thanks
which way do i turn the adjusment screws for more fuel/less fuel
hey Cody, i have a 2003 660 raptor and the left manifold (if u see it when you got on the atv) was drilled and my bike does not start, help me please!
thanks
I thought you were full of shit until I saw the cigarette in your hand. Then I knew you were legit. Lol. Nice video.
hey ii had a question for you, i have a yamaha raptor 2004 660. and when i turn it on it stays in but when i give it gas it makes a weird sound sounds like if it was choking on to much gas any idea of what that could be/
Luz Rodriguez did you fix it? I have the same problem
@Cody Sheets Should both the flaps open at the same time or do they work one after the other? And also, should high rev side open all the way up flat, (90°turn) or only about 3/4 of the way? I'm excited to ride. I gotta get the carb right and I'm having starting problems too.
should open in sync. one side has different size jets that's it.
