A little boggy

I got the sled out for the first time this year. Since we had a blizzard yesterday most of the snow is in hard piles but at least its good to see how the machine it running. What issue I'm having is its a little boggy from a dead stop. Some background. The sled is a 1998 Indy 500 carb with only 367 miles. Really, only 367 miles. It looks like it just came off the showroom. Anyway, the carbs are clean and adjusted the way I think they should be. When I got it the air screws were at 1.5 turns out. I looked on line and see the owners manual supplement says .75 out - so that is what I adjusted them to. It is much better than when it was 1.5. Now I'm not a small person, 6'6" and 385 lbs. X-college football player so maybe it just my weight bogging it down. I have to say the belt is also the original one - maybe it dry??? It did seam to be better the longer I rode it, about 15 minutes. Once it gets past the initial movement it goes like crazy, I'm really amazed how much power this thing has as it gets going. But I'm basing my experience on an old JD Liqufire. Any help would be appreciated. Thanks.

well you have to let the sled warm up alot lets start with that :p i say about 5 minutes after itll idle by itself(no throttle or choke needed) im sure oyull hear lots of other things umm then after that you can change your spark plugs make sure you got high octance fuel(even highest octance pmp fuel will work) and maybe a new belt. and if it still bogs it may be due to the fact your a giant dude :p no offence but you nearly tripple my wheight im just a little guy:p so ive never seen it as a problem but if your will to lose a bit of top end speed you could also gear it lower

Another thing I did'nt mention was there seamed to be black dust on the belt when i parked it. Since the belt is the original, 11 years old, maybe it just dry at the outside?

Whats a good belt for big guys?

The sled has'nt really been out and run for 5-6 years until now so maybe things just need to get loosend up?

well im not 100% sure what size but your probly gonna want to buy top of the line for a belt consider all the extra wheight the sled has to carry and your also gonna make sure to break it in soo no hard acceleration as soon for a while to find what belt you need for it though youd have to either check your onwers manual if you have one look for a number on the belt or call a dealer ... a polaris dealer not just a department store sadly they rearely no what there doing but defently a belt in a big part in the bogging

I had a similar problem and it turned out to be a dirty clutch, due to the belt burning or something at some point. I've used a scotchbrite pad and WARM water to clean all of the residue off of the face of the primary, and secondary if possible. I also replaced the belt, the replacement belt i had on hand was slightly used, but i have heard that you should wash a new belt before you put it on, because something used in the manufacturing process can cause the clutch to become slippery. Hope this helps

ah yes good point indy trail defently want to clean your clutchs and belt i wouldnt worrie too hard about actually srubing your belt though it could seriously hurt it id just blow it off wit hthe blow gun from a compressior or if you dotn have that wipe it down with a rag cuz a wet belt is a burnt belt

I did a quick look and see the following belts fit my sled, acutally many Polaris sleds.

Gates extreme 38x4730
Dayco HP3020
Dayco HPX5013

I think Mills Fleet Farm carries Dayco's

Was a belt? Hmmm. Dawn dishwashing soap and water I assume. Probaly mold release left on the belts. Usually mfg's use vegitable spray so Dawn should do it.

How do you get the belt off easily and not cut it off?

depends if your sleds got reverse or not probly not if so spin the shiv closer to the tunnnel backwards and push toawrd the tunnel it should open your cluthes pull your belt up and then over simple as that or if you have revese i think you need a tool to spread the clutchs not sure thats how the new ones are

I pulled the plugs first thing this morning to see if its rich or lean but the plugs look clean to light tan at the electrode. (Running iridium’s). I'll try a new belt and clean the clutches. When I was riding it never really started out slow or would go 5-10mph consistently, it really wanted to go 25mph plus. Thanks

When I bought it last spring I went though the tank and replaced all the fuel and other lines to make sure everything was clean. I also replaced the hyfax, all springs, air intake foam and air box foam. Basically its like brand new agian. I picked up a Dayco HPX today so we'll see if it improves. I talked to my local dealer, which is also a freind and he said the older Fuji's really work best when warmed up, about 15 minutes or so which might also been a contributing factor since I only let it warm up 3-5 minutes.
