Hi I have a question: my speedfight 3 ac 2t, has problem with kickstart and electricstart: the fuel pressure seems off (the fuel go’s up and down). It doesn’t keep the pressure so that the fuel reaches the vacuum pump. I am not sure wether I have placed my vacuum pump in a right spot. It is near the 12v buddyseat cables.
I've found that E5 causes the washing away of engine crankcase sealant around the crank bay area on three 125cc 2 stroke single engines that I've had to re-seal with ethanol resistant Blue Hylomar. Around the crank bay area all the factory RTF or previous rebuild silicone was gone, which was why the engines had started burning their gearbox oil.
This is because ethanol dissolves silicone & RTF (original black rubbery factory crankcase sealant).
and thats e5 so what do you think e10 will do lol
Hi mark where can I get a carb gasket set? I have the same bike and it’s not running it does run takes forever to start once it starts it’s fine just takes 30 mins some days
How long will it last tho???? As i seem to have the same problem and also the garage basically did what you did and my bike lasted 1 journey before dying again/ after spending 240 pounds at the garage?
i use e10 in my 2003 Peugeot vivacity, it’s very similar to the speed fights in terms of engine, I’ve had no issues since I replaced the carb and change my head to 65cc airsal sports kit, but my original 50cc piston rings broke soon after buying it ( only had 8000 miles on it or so) thinking about e10 my have caused that, I also premix all my fuel going into the bike, anyone have any thoughts on this?
2 & 3 star petrol…, those were the days!, and an attendant would often fill the tank for you! (with a smile!) 😂👍
good old days but no attendant in southend pmsl
do miss them as i was 16 and riding a 50cc day time and at night i had a suzuki x7 250 that i used to race around on
@@marksavage I was on a Team green Kawasaki AR50 at 16 but put 2 or 3 star in my little Yamaha TY80 as a kid!
@@hgvmatt6710 i so wanted a kawasaki ar50 but gave my dad £150 to get me my first bike and when i got home he had bought me a tomas 50cc !!, my life was over pmsl
@@marksavage 😂brilliant!👍
Rubber parts can be replaced with vitro parts,e10 can also ruin the crank shaft oil seals if they're not made of vitron.
all in not good stuff at all
Love your videos watch them all was hoping that you can help trying to fix a Suzuki burgman 125 a 2002 model getting a ticking noise but no spark have checked starter motor coil and tried the screwdriver across to bypass starter switch still nothing as your a scooter or moped wizard any suggestions thanks for your time and patience
No spark bud cdi , stator coil, ht lead/ coil , plug
Get a volt meter and work your way backwards
@@marksavage thanks and be watching like your channels mint have noticed that when trying to start battery goes low and horn stops working then switch of couple of mins checked battery with multimeter and full new battery on will that mean cdi as checked and changed will that stop when jumping starter with screwdriver nothing? Stator coil I think got video on hearing but can't seem to send it on my page
Hey mark how are you ? I need an oil pump for my speedfight 4 electric mikuni do you have one ?
Hello mark another good video I’ve got to admit I’m still worried of rebuilding my aerox so basically the only fuel to premix is super unleaded
Yes bud , that's what I'd use , well till they stop that in 5 years !!
Bugger lol
@@marksavage well on the 23 I’ll rebuild it and let you know love the video mark one thing I like about mark he’s down to earth and says it how it is no beating around bush keep it up mark good work mate
@@kayone8571 thanks bud , means a lot
You missed about the cuppa lol
@@marksavage 😂😂😂
Yamaha say it's fine. But I won't be putting any in my aerox.
My typhoon hates it.
i hvae a problem with mine it will run on rich for some time and shut down if i change it a litlle bit more lean doesnt even start i would like some help
I’ve filled my speed fight 3 50cc (LC) 2010 3 times with the new E10 and it actually runs better, it feels like its got so much more power and climbs big hills at 45MPH it’s used to do 35MPH
Probably your mixture thats perfect for the time of year. If you dont mess with it
while its running all good bud, dont leave it in your tank if you lay it up over winter !
some have said this but using so much more of it too
Actually leaded petrol sold as 2 Star (94 RON), 3 Star (97 RON) & 4 Star (99 RON).
was that what is was , i was only 16 at the time and had a stupid moped for the day and a suzuki b120 and a suzuki x7 250 i used to ride around at night
oh the good old days lol
With the fuel shortage atm i couldn't get E5, had to stick a full tank of E10 in the Car, but ill be using E5 soon as the tank gets low
yes bud that should do to much damage end of the day
If it’s a help to anyone smear a bit of grease on the gasket to help stop ethanol penetrating the gaskets.
it eats into it bud and will damage it no matter what you do , just dont leave it in you tank for long
Hi Mark could really do with your help. My sons scooter just stopped working I have changed the stator, the regulator/rectifier, new ecu, new ignition coil, new spark plug and the side stand switch but still no spark. There is power in the ignition coil but none when spark plug is inserted. Any ideas welcome xxx
If you know the coil has power, and is goo. Replace the HT lead and plug cap. Then see if you get spark from the coil to the plug.
if you have done all that bud id be looking at your cdi again , power going in and back out as you can buy a duff one
get a volt meter and start from battery and all the way along , dont forget wd40 all wires and make sure no breaks
Hi mark I took my speedfight 3 apart to re spray the body parts on it and I found a pipe which wasn’t connected to anything looks like it’s for air flow as it’s not from the radiator or anything the pipe was hanging down underneath my plastics and was clipped up to just under my seat do you know if it’s for anything important I’m thinking it’s not because the ped should have broken already if it was important it’s just a black pipe with a black box connected to it and on the end it looks like a showerhead end let me know what u think it is as I can’t see it on the owners manual or anything
It's the grv gas recycling valve
Don't worry about it as it would have gone to your exhaust
Take it out and chuck it bud
Oh okay the garage I braught it from had to change my exhaust as something went on it and they put a after market exhaust on it so is the Grv not needed then if I have a aftermarket exhaust
@@jack2010howe no bud not at all
Hi Mark, I have a vespa Lx 3v 125 2013 plate..
What type of rollers, clutch and exhaust would you recommend? It does about 62mph stock
Haven't really worked on them
But a sports exhaust will definitely help
Still with the same of 1g per roller extra
But a good clean up and check belts ok
Also a small upjet of 4 will help
Doesnt the fuel pipe sit under the frame so it doesnt get pinched ?
No there's a gap for it and the cable but not for the plug
However if you want to put it under you can
To be honest it doesn't matter
I don’t know where your base is but can you fix my Gilera runner vx125? I am having puppies with it. Fuelling/starting problems!!
You should put puppies in your fuel tank !!! Pmsl
Essex bud but most of my speedfight , aerox dna, and even the nrg should help
@@marksavage I’m Essex too. I just never assumed. I will be checking out some of your other vids. It all started when I fitted a new manifold. Up to then it was great.
Super unleaded is still E5 at the moment,in the old days it was 2 3 and 4 star.
Yes bud
@@marksavage hi mate have you got a video on taking a tank off a speed fighter 100cc plz I put diesel in my tank ino is very dump 🙈
Why do they say "2T" ,I am guessing you are talking about 2 stroke but I am a bit confused, PS I am 56 years old hence I am wondering why its called "2T" very good videos by the way.
Hi I have speedfight 3 it sparks when u first turn key and then it doesn't spark
Did you get solution for your problem ever? I have same situation.
Bit of a subject change how do i stop the clucth on my bike from engaging to early
Is it a scooter clutch/centrifugal clutch?
Have you changed anything in your transmission I.e. rollers?
@@pedshed5132 yes it's a x8 125
You can change the springs or renew but most work standard bud
@@mdmotorcycles10 when I use lighter rollers I find my clutch engages at a higher rpm, and vice versa for heavier rollers. I’m not too sure why but if you want to engage later I’d say choose rollers about half a gram lighter.
@@pedshed5132 i haven't changed the rollers yet
Hi mark i know this is a old video but im really having issues with my speedfight 3 50 lc ive got the idle screw all the way in and throttle cable screwd on the last threads to idle and really badly bogs on acceleration lumpy idle and black spark plug its had a new top end as badly scored so bought a narauku one and leo vince exhaust and new inlet manifold and reeds and crank seals but still having this annyoing idle problem and bogging
Take out carb and jets
Clean and try going smaller on the main jet like to a 60
See how big it is now but this will help and check the seals and air box is on tight
Do you have the link pipe on ?
@@marksavage what u mean to a link pipe on
@@marksavage and where does needle have to be
@@gazzayoung7333 the air box has a pipe that goes into the variator cover on sp3
@@gazzayoung7333 the needle , best leave it as was or on 2 , middle
3 half to start once re jet to start
Hello mate why wouldn't the pipe 2 the casing be creating pressure to work the feul pump?
what ped bud as in name and 2t of 4t
pipe to the case ?
not carb
@@marksavage speedfight 3 mate and 2 stroke
@@marksavage pipe from case 2 the feul pump
@@dwaynemoloney3338 fuel comes out of the tank under the seat into the vacuum two pipes come out
One to the carb and the other to the inlet manifold
Oil tank goes to a pump and then into the carb
What pipe are you talking about
One egv comes out of exhaust and into the frame
It does nothing and can be cut off and bent over
Case is just to vent heat from the varitor
@@marksavage ain't it the vacuum line from the case what makes the feul pump work as its not electric
Mark could you find out where he got them bolts from and link it below please
E bay bud , best place to look
They are good
@@marksavage I've looked on Ebay can't find them anywhere reason why I asked, I should of said in my first comment lol
@@sgt-bald-pigeongaming8996 oh maybe lol, gsxr forums or Google search bud
I hate to be one of those people correcting you. But it was 2 star, 3 star, 4 star pertrol. Not two stroke, four stroke petrol. 😂
But you know that Mark.
Oh yes the joys of swapping out not rollers..
My typhoon is loving 97 super after that carp E10. Even 50/50 it was well down on performance.
Take care mate.
I get one thing in my head then it all comes out pmsl
But yes bud you know what I was ranting on about lol
Take care bud
9:30 what does that cable for the seat do?
the cable comes for the key ignition and open the seat bud
@@marksavage
Thanks for the reply.
I bought the exact same scooter when I saw your vids. Really like your vids. Hope I can fix my scooter haha
I've switched to Tesco super E5 99 Ron. The bike runs fine but won't start easy now. What is the problem?
had you used E10? give it a service bud so new plug and air filter and see how it goes
@@marksavage I changed the plug, it did look a bit ugly but not white just a usual rust brown. Seems to have gotten used to super unleaded. I don't know if that's the malossi Digitrontic at play. I've asked everyone but do you know if you should remove the secondary air system box as it's not connected to the power pipe? Some people say leave it on and others block the hole with a car wheel bolt. The Digitrontic handles the sis valve but does that box serve any purpose now the exhaust is gone? I would really like a definitive answer as it doesn't seem to serve any purpose.
@@Antidoton it can be left, or take out the bucket and take it away
But has no purpose now
As for starting yes gibe it a little time to settle in
@@marksavage Thanks Mark it's been a question I could never get answered? Should I plug up the hole where it went (I hear a car wheel bolt fits nice) or is it ok to leave it open. Sorry for all the questions. Your videos make me wish I lived next door 😁
Ok let's open this question up !!
Speedfight ?
Air box ?
2 parts air box and extention pipe
Some like it on other don't once upjettted etc
If not connected it leaves the open part of the air box
Leave it
Exhaust ?
It has a GRV !
Most disconnect it and bend it over
Pipe left
You can take it out or leave it
Please explain more or do a video of it, then 8 can see what you are talking about
Don't go blocking this up if you don't know what it is bud
So give me more info
That nasty e10, just destroys some types of rubber
It is bud
I have a BIG problem with a SF2 LC. I am almost 50 years old and have a lot of experience with 2T but doesnt have any more ideas on what to do.. Can I send you a movie of how it sounds and what I have done?
I watched it so we're you riding it and it's not revving right / running ?
What have you done so far ?
Was it running ok before ?
Serviced ?
Tuned ?
Carb cleaned ,what size jet?
I have lots of videos on my channel to help
@@marksavage cleaned carb, changed carb and still the same. It is not revving right. Right now main jet 54 the other one 35. It had been like that since we bought it tfebrary this year..
Running bad from like 1/8 to 6/8. Runs pretty clean and fast on full throttle..
Changed to smaller and bigger jets, no difference
Moved the throttle neel, no difference.
Changed spark plug, no difference
Checked and cleaned air filter, no difference
Changed variator rollers, a little difference but not much just lower full speed. Got 6 g weights in right now!
@@danielmagnusson5366 54/56 standard jet
Leave idle jet go to 60 main
Then tune
Needle middle
Check reeds !
@@marksavage a lot better now but even better when I removed the air intake box from the airbox (wit the filter).
@@danielmagnusson5366 more tuning , do u have the link pipe on ,of so take it off
Bit tuning bud
Oil injected 2 strokes, as opposed to the pre-mix 2 strokes, have the biggest problems with E10, due to being run right up to the edge of under lubrication.
Just adjust your pump or add to gas?
the 2t doesnt mix well but you can buy some that do, but me i'd use super bud
hi mark im after a bit info on carbs if u dont mind helping me out is there any were we cud chat on message or skype or even on the phone , just cant find anyway on hereto message you direct
i have many videos on carbs bud 2t and 4t on setting up
upjetting and cleaning
chat on here bud
@@marksavage 4t clone bike bit similar to the yamaha wr 125x i have a 150 big bore to install but was stuck on finding out how many sizes to upjet the carb
had a full lock up on my girls scooter with this crap ....... filled it just once :(
oh wow that bad like this one really , its not good stuff and many more will break down
