Will seafoam fix my boggy snowmobile? Bog series #7 Polaris indy lite.

[@Aaronwestsidetire]

Just watched all the videos to be left hanging, what’s the word, did u get it running, finish the series for us.

[@wthomasw2]

I think to help this sled you need to invite larry enticer so that he can "send it" it will run fine right after!

[@hondabiker2653]

I watched all 7 videos so far on the lite. I recently revived a 94 that sat for 8 years. I just put a new track on (xlt light weight z track) sliders, and any bogies that were warm out. Put new fuel lines from the tank to the carb. New oil lines and filter. Cleaned the carbs. Put a little premix down the cylinders, ran premix in the tank to reseal everything. And it fired right off. Machines odometer stopped working at 4600 miles 15 years ago. Still a strong machine, hand warmers, and lights work. This is a great example of what Polaris reliability used to be.

[@Joeys990]

Try lighting it on fire. That should take care of any bog issues with it , once and for all.

[@philblodgett4944]

Love your channel, thanks for taking the time to put all this good info out there on all your videos, anxious to see how the old girl comes to life with the lower pilot jets!

[@thomasmcpherson7584]

My experience with Seafoam: I didnt believe it was great. I thought it couldnt do much.
My mother has a 2011 skidoo 600etec. We are at camp it wont start. I finally get it to barely sputter to life. My friend has a can of seafoam. We put a good amount into the fresh tank of gas. The sled woudn't even move. Once idling for a good amount of time it was able to crawl around on one cylinder and sputter like crazy. This sled is made to run 91octane and has always ran 87octane. So that being said, the valves were probably gummed up and the injection system was probably gummed up and the plugs were probably bad.
So after a morning of opening up the throttle and letting it sputter with the seafoam by the after noon it was idling like a champ. it has a small bog in mid range and didn't have full power. but it was vastly better then the first morning. The next day we put the rest of the bottle of Seafoam in the sled and continued to run it as we were icefishing. By noon time the sled ran much better and as the end of the day came, me and my mother were able to go on a 40mi trip with no problems.
I fully believe that seafoam can clean internal part over time. I believe that it can work on some problems, but not all. It is a product that does what it says it will do, people need to understand that it takes time to cause an effect.

[@lifebeginsat190]

I just watched all videos beginning to end...kinda disappointed you guys threw this sled behind the shop and forgot about it...I wanted to see it fixed

[@jrhaines30]

@Mason Wengeler They ever finish this series?

[@LifeofAedan]

@@jrhaines30 must be stumped. That's how I am on mine. It's honestly the worst shit

[@ScoredPiston]

Everyone speculating - I know I’m late to this party but by a couple years but it’s an easy diagnosis:
Take belt off - run engine, if it has a bog then it’s the engine, if the engine runs good then put belt on and run it. If it bogs then it’s the drivetrain (clutches , maybe a bearing going, track too tight, etc).
Didn’t watch the whole series but it needed a compression test after he rebuilt it, not sure this was done? If the cylinders are blowing by then that would be my only other suspect if the drivetrain is good but it runs good without load but bogs when u put the belt on. New pistons won’t fix an ovaled out cylinder........

[@markrabe9812]

Just replace the coils for 30 bucks

[@Z-Bart]

I had a brand new 1988 340 Indy Sport. It was far from snappy on low end hole shots. This is what I remember doing. Remember now we're talking 30 years ago. From the factory there were FIVE clutch shims on the secondary clutch. I think we took out three. Tightened the spring one hole on the secondary. I think we did down size the pilot jets and set the needle clips on #3. I put well over 5000 miles on that sled. Never lost a race to another 340. EVER.

[@davemartino6534]

I had a similar problem bog (no warm weather top end) on a 81 Poo Cutlass 440 SS. Went through the entire motor. Still was the Gutless. I accidentally started it without the airbox and it hit the spec RPM's. Decided that the factory had spec'ed it to rich. Put in smaller main jets and voila. No more Gutless. Glad you mentioned this in the video. I enjoy your channel.

[@johnvanvlaanderen5108]

Please find the time to get this sled tuned! I am having the same issues with the same sled (in the 2 up tour pkg) and am totally stumped.
Fantastic vids with great "no bull " information

that's awesome thanks for watching!

[@jci_log1631]

Hey, really like your videos. I think your right on the money with needing smaller jets. Keep up the great videos, and hope we get some snow soon here in Innisfil! Cheers!

[@nathanmartin7010]

man the Indys have had a bog right from the factory I had a 400 an it was always boggy on bottom end with full rebuild from the dealer Louis

[@craig659]

I have a 340 Yamaha that kinda had the same problem it had resister plugs in it I am the original owner and after they went to ethanol gas it would never run correctly I changed the plugs to a non resistor plug and bang it run perfect. Still have the old girl 1980 340 enticer.. never ran better..

You just leave us hanging on the 340 Indy not cool. Especially when I've watched all episodes. Thanks for what u did show though.

I had a similar problem with my '90 Indy 400. Dealer discovered main jets were wrong or one came out. Don't remember which one. Might help to rebuild the carbs. Good luck.

have you checked the expansion chamber for a nest?

[@NewfoundlandBen709]

Hey I have a suggestion, same thing was happening to my machine and it turned out to be the coil, it was always getting spark but wouldn't run the machine properly

[@kurty240]

Did u ever end up fixing the bog?

[@matt0725]

We had almost this exact problem with a 98 500 liquid and a 500 air and bought the $30 something dollar gasket kit online and pulled and rebuilt the motors and they RIP now. Even before the bog we never realized how down on power they were. Both Polaris^^

[@ClickinChicken]

Thanks for video series, enjoyed myself.

[@machine7767]

Did you ever fix the bog? Wish you would have shown bleeding the oil line. Did you install an oil line filter?

It's the choke cables stuck I had the same issue

[@dylanengland4113]

Love you vids. They help me out

[@edwinlehman2841]

You got a weak coil And bring your rpm up about 400 RPM for engagement so a stronger clutch spring will give ya some zip .Great videos thanks fun to look at your short movies you really are helping folks well done

[@PowerModzOfficial]

Thanks for the tips!

[@otahu26]

Low elevation- or warm temps= Smaller pilots, 1 size smaller on Main Jets, Needles in #2. Air Screw 3/4 turn out, Vent tubes in Carbs attached to air box)helps even out float bowl pressures. Big kids and Young kids will love it :) plus you'll be getting 15 mpg average.

[@neon922]

Indy lite air screw is 1.5 turns out

[@otahu26]

@@neon922 yes 1.5 turns out, that was factory. I didn't write about factory or warranting a snowmobile 30 years old. I wrote about how to remove the boggy issues and get pep into a 340 sled engine. Clutching plays it's part too and gearing... Our Oval sleds are 340's and do 105 mph on the ice ovals ;) :) I know Mr Powermodds isn't looking for ice oval speeds.
Venting the Carbs to the air box instead of the hoses being routed to the upper handle bars will provide more stable and constant vacuum pressure for the float bowls. Throwing off all the other factory jetting. Sled Manufacturers started doing this back in 88 with productions sleds till EFI came into play. Always test and tune though.. A jetting slide rule would be helpful also.

[@neatstuff87]

Just got a Polaris Sprint 340 with the same problem. It’s fine when you first fire it up but after she warms up she bogs. Once it gets going it’s fine. But from a stand still and you start off she bogs

[@ratoneJR]

Sea Foam takes time. Not instantaneous.
Use Sea Foam in every refueling, use it at half strength. You will NEVER have a fuel issue. I do this in mowers, snowblowers, chainsaws, weed trimmers, etc. NEVER had a fuel issue in 15+ years. Sea Foam in every gas can...every time.
The little this costs is well worth the hassle it avoids

[@philkennedy2880]

Going through this exact problem right now with my Indy lite. Hopefully theres another video to come? thanks

[@PowerModzOfficial]

[@ldg332004]

When a guy is expecting a happy ending,you can't take him there then leave him on the edge. Am i right......

[@scottcarruthers9204]

Just gonna say that it could be a weak coil or the stator

[@colekreger7825]

Get a hand held tach and check your engagement rpm. I been going through the same thing with a lite gt and 340 deluxe. Runs ok once going sluggish off the line. Put a new gold spring in the Gt and it help and brought engagement up to 4500 form 3900. However after checking a whole list of things like you have I'm pretty much at the conclusion these sleds are geared too tall 16/39 on the gt and 17/41 on the deluxe. 18 and 19 top gears are available . But not 14 or 15. No way to gear the chain case lower.
Also I have put a 1.25 track on the gt from a .750 ish one. (more drag) So the deluxe is getting rebearinged today and dropping the track drive sprockets from 9t to & tooth, a PPD- 04-108-55 bravo long track drives. I can always go back taller in the chain case if needed. 0102-297 PPD is also some 8t drives for a 2000 bearcat 340. I'll report back and let you know if the 7t was too much as I'm not 1.22 under original gearing. But on the stand this thing will turn the track 85 mph and on the trail lucky to see 65 on the dream o meter. I think the low gears like the Bravo runs will make this a much better kid sled 95% of the time they way a kid uses it. The speedo is going to be more like Km now then miles.
The other thing on clutching is to check the main bushings because as they wear the clutch faces can tilt out to a V rather then be parallel.
Compression at 120 lbs is ok.
Pilot jet are tiny on these 340 and do clog easy.
Belt wear is a big factor in bogging too (lose the lowest ration needed to start moving)
Using mountain clutching setup would help takeoff (I'm near sea level) but then you get a jumpy sled that is hard for a kit to control, so at the end of the day gearing down is the best option imo.
Just don't hold the sled wide open on a ice road for 2 miles trying to squeeze that last 3 mph out of it as the engine may be over reving and there is no tach to verify your above 7000 rpm

[@thatalaskaguy]

My son’s Indy light was boggy and ran crappy this fall until I put a whole bottle of Sea Foam in the tank and just rode it around at high speed. It runs fine now. Funny I ran across your video months later with a similar issue.
It also looks like warm, spring time conditions in your video. Fan cooled sleds always run a bit boggy in warm weather unless they are jetted leaner for the temps. But then you risk burning them down when it gets colder and who wants to spend the time jetting a fanner? I love fan cooled sleds but they’ve got their idiosyncrasies. Overall they are easy to live with though.

[@hollowscott]

You have to run it hard and hot after adding. Use it all!

[@PlayerOne306]

Breaking in a rebuilt engine is the tricky part in a fan cooled just had to be correct ratio

[@SuperHungryhorace]

I'm really waiting for the next installment in this series. I have a Polaris 340, and for the 10 years I've been driving it, it has always been boggy. I installed bigger carbs, but all that got me was a better top end performance, and a hole in one of the pistons. But it didn't make the bog any worse either. If you manage to figure this one out, you will make both me and my 340 happy :)

[@PowerModzOfficial]

its just about off the shelf and ready for work - but not quite yet

[@blainesloan6200]

From my experience most of them old Polaris sleds bogg down off the line and on low rpm's I came to beleive it's a bad porting design mixed with small diameter carbs

[@jackfrosty79ify]

[@Doonit_hard_way_since_65]

Seafoam... highest priced coleman fuel + alcohol + mineral oil on the shelves. Needed to let it run at least 30 hours while riding naked in Jan, that is what it takes to make seafoam work good.

The exhaust might be stopped up. If its not the exhaust I think the timing is low. I'm not a certified mechanic either but have worked on a lot of motors, I mean engines lol.

[@TheRcscalebuilder]

I just had the same problem with an indy lite, turned out to be the pickup line in the tank had rotted off and the machine would intermittently starve for gas causing the bog. might want to have a look and see if that's still there. Good luck.

[@carmichaelmoritz8662]

so i am just wondering did you ever get the crank looked into . there is a special piece that is in the centre of the crank and divides the bottom end preventing air exchange from one side to the other . another thing i found is that some people remove a piece from inside the airbox to improve air flow without realizing the piece is needed for one the motor warms up or is used on a ward day . that being said i still think its either the carbs or the motor that is causing the bog . those polaris fan cooled are about as good as those fan cooled motors used in the ski doo model . i wish someone would explain why the liquid cooled are so much better than those particular fan cooled .

[@carmichaelmoritz8662]

and when i say the motor i mean something on the motor like crank seals or something leaking air into the crankcase .

because you rebuilt the engine, carbs and fuel pump it can only be stater,coil,wires,plugs ect. OR clutchs but im thinking stater or coil breaking down after 3-4000 rpm

mabe its something with the timing or spark.. or i have seen clutches cause bog before

[@griffinlang893]

I know you may have thought of this but make sure that the motor mounts are solid because it looks like the engine is moving which may cause the primary clutch to moving backward causing a bog. This happened on my snowmobile and I made a huge improvement when the motor was moving as much. Is it mounted using rubber spacers or is it solid mounted?

[@thomasmcpherson7584]

You should have added a splash to the oil container. A little in the oil can help clean the oil parts. But if the motor doesn't have an oil container then just forget that idea. but seafoam is fine in oil in small amounts.

Did you try to synchronize the carbs to the correct spec and reject it to the correct spec also primary and secondary clutch

[@bradg8814]

Did the pilots works? Have to start mine fuel off. Run high for a sec then bogs and half to flip the choke real quick to get it to idle up.._ but when idles it will bog a die aswell if choke was missed then i have to shut fuel to restart the 92 indy 440 lc .. Everything new inside out . Cards fully rebuilt to stock. Oh and runs best with needle clip on bottom notch.

doobyboy21 oh heck ya I don't burn people and I use good ideas as process of elimination

[@supafrancis]

When seafoaming a car per se, you suck the seafoam directly into your throttlebody via vacuum lines... Your just shooting a cleaner right into your airpassages and strait onto your cyl.. With carbed motors, you want to do the same thing when it comes to seafoam. Saturate every passage and jet that you can with the stuff until the engine dies. I attach a long piece of fuel line from the filter to the carbs, start the motor then pull the line from the filter and spray seafoam right into the carbs while working the throttle until it dies out..I use an oldschool brass oil squirting gun with a nozzle that fits right in the fuel line and usually get 3 or 4 seconds of HEAVY dark grey smoke then 5 to 6 of thick white .. You can let it sit for a few minutes, attach the original fuel line and start it to see if it cleared it up. Or you can do the rinse and repeat method if you noticed a slight improvement and see if it gets better a you go. OR....fi the carbs until it dies and leave it overnight! heck, leave it for a week.. a summer even! kidding... but who knows? I have gotten a few dirtbikes running using the overnight method when they had 10 year old gas in them and who knows how varnished the carbs were.. Literally, $150 barn find cr125.. not touched in 10 years. Drained gas, plug gas overflow line, shot seafoam down fuelines, let sit overnight, fresh gas in the morning, and 10 years of carb gunk came shooting out the pipe in 15 seconds of gagging, sputtering and chiking until it smoothed out and purred like a kitten. Did it with a KDX200 and a DR350 as well.. they all ran great afterward. Just a suggestion since you said that you will be trying it again. Good on ya bud!

[@PowerModzOfficial]

This turd will be taking it off the turds sled rack in the next couple of weeks. This turd can't follow up on it until I have something to follow up on - the turd will fix it though as that is what this turd does. Thanks for watching this turds videos!

I found older Polaris sleds are worse than any others for those bog issues... i have the same year sled as your axys without all the addons same color and everything kinda funny how that worked out, i may turbo it yet if i makes plans for the mountains but for now its enough for these old shoulders to hang onto for sure.

[@neon922]

Dude the air screws are off back them off 1.5 turns out instead of 1 turn. Polaris specs 1 turn out for most motors but the Indy light has 1.5 turns out. This is a huge case for 2 strokes bogging when accelerating or a high load is applied at low rpm.

[@ArcticJeff]

I would agree with jetting it down. It sounds like its running rich. At the least, try it and see how it runs.

[@benjaminz8977]

is the crank shaft seal properly seated/ in good shape? maybe you get the bog from an issue there...
