Polaris INDY LITE 340 BOG SERIES #8.

[@stevegraves2890]

Those old Fuji engines are awesome. The 340, 440 and 488's where some of the best engines ever for simplicity and basic needs. Easy to rebuild too.

[@PowerModzOfficial]

I agree

[@yourselfdotcomlol]

Doing one now and couldnt agree more. Perfect first engine rebuild for my 8yr old son and I. When its done he gets to ride it all winter

[@mi-kwan_tait8031]

Honestly so glad you started the bog series back up, I've been using it as a kind of guide for fixing up my 2000 600 indy xc deluxe! Was sad to see the series never got completed until now! Great videos as always.

[@PanDanout]

@Powermodz -I had a Polaris with the 550 fan, very similar. I had the same bog issue, I rebuilt the motor, new reeds, rebuilt the carbs and fuel pump, changing and adjusting the enricher valves and rebuilt the primary clutches in the hopes of getting rid of the bog. After many head aches, carb adjustments and jets/needle adjusting I narrowed it down to one carb. I vacuum tested it an all. It would start fine and on the low end was perfect. Everything about it screamed it operated normally. I placed sled on stand and ran it at 4-5k for a few minutes and shot each side of the exhaust port with a temp gun, one side was reading a lot hotter than the other. I purchased a used carb off eBay and rebuilt it with the rebuild kit I had bought previously and the bog was instantly gone. So just a heads up if shes still bogging give a carb swap a try.

[@PowerModzOfficial]

I might have to!

[@dirtyfacegeorge9938]

2 pulls no doubt,it's a Polaris 🏁

[@TheJumpmachine]

Mine have a bug to but 1 pull and start ahah

[@neatdreams]

I have one that have been sitting for over 1 years and no carburator clean 2 pull started right up!

[@boggerdak]

Have one of these, too. I was frustrated with the low end bog as well. Every old school Polaris guy I talked to said this is because it is a piston port engine. Has to do with fuel timing and air flow. The port in the pistons acts as a valve the same way reeds do. Only reeds react much faster. They all said to tune it as best you can and then clutch it to engage higher up, out of the bog.

[@PowerModzOfficial]

Ya thats what im thinking

[@peewee.3138]

My dad had a ‘91 Lite. Once the engine was warm, you could grab the primary and give it a pull and it would start with your hands!

[@nativenation3296]

I've seen someone start their sled that way, and it worked...

[@luuk-out-below9804]

Ha see that sea foam you put in 3 years ago just needed some more time to regenerate the sled, 3 more years and she'll be like brand new. Love the coyote helmet. Glad you're back on this.

[@PowerModzOfficial]

That's the plan!

[@yvonviau5791]

Just finish with this problem . To start, i wasp out engine same carbs same bog out, pour response at low RPM . Air box has some fuel in it, air screw does nothing , So readjusted float to have less gas in bowl . I set it all back up and know air screw works . I run it , stop and go many times , no bog . To me the floats need to be replace . It was running fine for years before ! So fare this is working for me . Thanks Yvon

Good to know!

I have the same exact sled except it is a deluxe model and it’s a absolute ripper! It sat for 15 years and we replaced the gas, fuel filter, carbs cleaned, and it runs like a top. I made a couple videos on my channel showing it off!

[@PowerModzOfficial]

Very nice!

[@alangolat2907]

Good lord have I been waiting for this. I have a 88 Indy 340 with this same problem. It’s definitely a fuel issue. I even have to pull plugs and dump gas to cold start her. It runs like hell low to mid rpm. But WOT she runs like a champ. I call her my chainsaw.

[@alangolat2907]

And why if everything is stock would the jetting need to be changed. Is compression/suck different than factory? Is fuel from 30-40 years so different it requires re-jetting? I know many who are perplexed by “the Bog”.

[@bigalbranim614]

Also working on a Indy lite with a top end bog, please continue

[@robm8089]

That machine sounds like its running pig-rich to me. I would say it is taking in extra fuel somewhere or airbox passage is clogged. Take it for a ride with the airbox removed to eliminate air duct blockage. I would also throw a timing light on there quick to verify ignition timing quick too. Then check carb body to float bowl o-rings(on those old style polaris mikunis with main jet in the side of bowl), fuel pump, or any possible area for engine to suck in extra fuel.

[@nsbfan]

I was new here 5 weeks ago when I was reviving some 27 year old sleds, the big series was my instructional, so glad it's back again haha

[@chimrichalds1422]

A leaf blower works well to check exhaust flow.

[@robertpronovost3839]

You did set the carb hight at the one point. I think it’s best set them with much smaller gauge as well. Then check the main cable that pulls both.

[@jamesmcrobert3286]

I agree one size up on pilots then tune with air screw and needles. bet it goes good with that. fun series!

[@tr4415]

Also the rubber carburetor boots... they connect carburetor to the engine... if you let it sit outside that rubber can deteriorate and get cracks in it... you might want to check to make sure there are no cracks in those rubber intake manifolds... if you will... no cracks... air leaks... good luck with it

Those in indy 340s are the best I have a fully mod one that had a dirt bike exhaust coming out the side

[@markbulva4188]

Two things. Is there not a bleeder on the oil pump and since the coils and stator are not adjustable I would suspect a timing issue. Perhaps low voltage or something

[@jasonmushersee]

had that same sled but brand new it always ran lean always bogged down in deep snow had to get off & push to get it moving it's a trail sled only. my 440 super sport those mixture screws came loose always had to open them on the trail several times/day ended up putting nail polish on the threads

[@prestonbear8981]

Have you checked to make sure the choke plungers are seating all the way in whet the choke is off? There should be a little play in the choke lever. Also, are the carbs/throttle cables synced? If not, one cylinder will be doing more work than the other, causing a bog.

[@PowerModzOfficial]

You bet!

[@g_central8473]

Try this. I have a xc600. Fighting a major problem with a bog. Did everything possible. One day I noticed it seemed to run better with the hood open. Ripped it through the feild holding the hood open. No bog ran like new. Closed the hood. Then bog. Exhaust had pin hole causing leak causing fumes to suck into the carb.

[@PowerModzOfficial]

Interesting ill try that

[@justbraaapit2311]

Yeah I had that same problem with the coolent and muffler bearing. All I had to do was smack around a few no it all's and it was fixed. Great vids bud

[@lazygamerz]

Check the secondary spring strength and what the primary clutch engagement RPM and what RPM it has through the pull. Steel springs weaken over time, so then the clutching gets thrown out of whack, and its like someone is always short-shifting your car before you hit the power band.

[@PowerModzOfficial]

It's a new spring

Raise the needles up one notch that should help richen her up a bit. For testing purposes id just close the air screws before I change any jets. You'll get it fixed soon.

[@cweinberg33]

Exactly, I stated raising the needles, lower the clips. The sled will rip with some fuel. These carbs run on the needles, right now it is just way too lean. Pilots may help with the transition to the needles. Great videos, much more enjoyable than the political bs.

[@419gates]

"Sorry Greta". Priceless.

[@tr4415]

Here's another tip... you can use this in all your sleds... there's a product called No More friction ionic friction reducer... molecular friction modifier.... I tested this product in about 2008 with my Freightliner fld120 against the mountain in Kentucky that I was climbing twice a week because that's what my job was at the time... instead of 36 miles per hour at the top of that mountain I had 46 miles per hour after adding no more friction... gross vehicle weight at the time about 70,000 pounds.... I use no more friction ionic friction reducer in my Polaris Storm... in the chaincase... in the injector oil... in the gasoline... and in the grease.... you want your sled to be fast.... you want your pickup truck to be trouble-free... get yourself some no more friction ionic friction reducer from Oklahoma Arkansas somewhere down there.... happy trails... TR Michigan... and PS..... also in the antifreeze nmf mixes with water... it de friction izes every part of every machine basically

[@tr4415]

I have a 1997 Polaris Indy storm 800 Triple Black... 2300 miles... it has three 38 mm Mikuni's on it... I wrench on it more than I ride it... it is the snappiest with the air screws adjusted to 1 and 1/16 turn out... right where they were on Yours... before you decided to go a turn and a half... a turn and a half out is too lean... 1 1/16 turnout.... and then just ride it and it should fix itself... they don't like to sit outside... basically like any female doesn't like to do... happy trails TR Michigan...

[@Ryan-vo3rm]

We have that exact same sled same colour and everything my Dad bought it brand new and they are surprisingly quick. Anyway I'll give a tip because we rebuilt ours and is working like new but during a run last winter that foam padding heat deflector attached to the hood above the exhaust fell off on a ride and almost caught on fire got pulled over and got flames put out before any damaged happened thankfully. Anyways I guess the glue that holds it to the hood dried up over the years and that's what happened so make sure that it's still attached good. Cheers👍

[@alexwalter1991]

Try changing the oil pump. When they fail they put too much oil in and that's why it would smoke so much at idle

[@TheTylerGreen]

[@tr4415]

Put the air screws back at 1 and 1/16 turn out... pour some berryman's B12 chemtool into the fuel... it will make the fuel extremely volatile... and it will also clean things as you ride... the sled should fix itself

[@PowerModzOfficial]

[@brandonwatson6941]

We have 2 indy 488’s. One has a bog like this and the other runs like a top. The only difference between the two is the voltage regulator isn’t working right on the good running one. Which means the light and hand warmers don’t work. I think there is a coil/magneto problem with the sleds that bog and would like to hear your thoughts on that

Adjust the pin in the carburetter plunger by the throttle cable Maybe that will help

[@Z-Bart]

@2:32 I know what the problem is. That drive belt should be sticking up above the secondary clutch by about 1/8". Take shims out of that secondary. For starters.

[@celiturbo]

My old xcr didnt like that dayco maxx belt one bit either, low speed backshift is way better on a new polaris belt. dayco maxx is just too soft for machines that are clutched for a hard belt. This 340 has bigger issues though. Best start at this point is making sure carbs, jets, needles, needle jet, throttle slides, clutch springs and weights are all correct to the sled. Lots of idiots out there that rather than properly cleaning carbs just get another set they think is the same or they order a rebuild kit they think is right, and far too often people try to swap jets around or change needle heights to make something run right that has has a crank seal out, low compression, bad clutch etc.. check the ignition timing also or at least make sure there is not extra witness marks visible on the stater showing its been moved at some point.

[@butterybird4987]

Hello, I'm thinking it's the spark plug coil pack. When it heats up weak spark causes the snowmobile to hesitate and feel weak/boggy. What do you think?

[@Ethan-ck6iz]

Seems like pretty much all the old polaris fanners have that slight low end bog to em. And polaris never really changed the carb setup on them throughout the entire production. Got the same bog issue as you. I'm about ready to chop it down to the lower compression numbers these motors run and say she runs mint... I also noticed on the 440 fanners that the SPI pistons aren't as close to the head as the Wiseco's, and I've had the rings come from the factory with too big of a ring gap from SPI/noname brand 😂

[@AndrewDittman-ti9vu]

I had a problem similiar to that, my fuel filter was plugged!

[@kriserling9048]

Any progress? Id love to know the culprit of the bog.

[@matthewl6183]

I came to the conclusion that my ol skidoo perhaps needed a fuel pump cuz the rpm ceiling kept getting lower and clutch work is out of the question and sure enough a carb reclean and a new pump and shes better than ever

[@PowerModzOfficial]

Thats great!

[@larryw5429]

Needles in the carb slide! Set it all to factory and if it doesn't run its in the clutching, cdi, or belt is not correct!

[@mitchcoop1]

I Watched series 1-7.. So Wait, Wait ...why did it run so much better when you started it, after all this time with 1 turn on idle A/f screws? Is this because of the assembly oil not burned out years before? Like you said.. OK...Turn the idle air screws to (1 1/4) and take it out, run the heck out of it for an hour, then check the compression. And see how it feels.
