k so i bought a 1999 600 xc sp im new to sleding i have a quad already.
i have a couple of questions about my sled like...

> i have a exhaust leak on my u pipe caused by the can by pounding at the top its a big hole like 1 inch long and 4 to 5 cm wide... its robbing power???

> and when i turn my clutch it seem to only compress one time its a twin so isn't it suppose to do it twice?

> do i change the motor oil or does the two stroke oil reservoir feed oil to the motor?

First off.....Welcome to the site and our awesome sport of snowmobiling. Your sled is a 2 stroke. Just add gas and keep your oil tank full above can. You never need to change the oil.

Big rok is correct never change engine oil but you should change chain case oil every so often maybe every 1000 miles or so.

Can you post picture's of the hole in your exhaust?

 

[MN_SlEdnEck]

i will tommrow its to dark out now

Your motor compresses at each stoke. It only does it one at a time. When you turn it over, one cylinder will compress then as you turn it again the other will compress.

A hole that big in the pipe will definitely cause a power lose and could potentially burn down the motor. Get it fixed or buy a new pipe.

It's a Y-pipe, not a u pipe, and yes, you should fix that because you're loosing back pressure.
Don't know about the clutch and most 2-strokes have an oil reservoir unless you go with a sno cross sled which most don't have a reservoir and would have to be premixed.
Welcome to snowmobiling. Stay safe and have fun.

Welcome to the site...dont mean to highjack the thread but is that a 660 or 700 Raptor?

FYI dont double post the same topic. See your other post for my response.

 

[imcrazed]

no dude its a u pipe its not off the motor its after the can


lol 02 660 raptor with just the k&n filter and power lid and the carbs are jetted

 

[bcole11]

im confused how is there another pipe after the can? just try to get a pic up asap it would help u out allot.

THE U pipe like at the bottom of the sled right?

I think he means the "U" section of exhaust after the expansion pipe but before the exhaust can...?

POST PICTUES! THEY ARE WORTH ALOT OF QUESTIONS!

I was tlakin with my dad tonight baout the hole in your Y pipe and if you have a wire feed welder like a millermatic or something just clean the surface around the hole and do some welding and if the hole isnt more than in ch you can probably just bead it over with some weld and that would hold until you got a new section of Y pipe

 

[bigrok]

It's not the Y pipe. It's a piece of pipe on the can that has a hole.

 

[marc]

A stock 2 stroke needs back pressure to make horsepower, get the hole welded up or get a new pipe.

 

[MN_SlEdnEck]

It's not the Y pipe. It's a piece of pipe on the can that has a hole.

Still, you can fix it just the same way. take a wire feed to it and tack it up

Ive been there done that and it didnt go as well as you might think. of course I dont have much seat time behind a welder, it does take some skill to bead over a fairly large hole especially if the material is thin and/or dirty. Your better off takin it somewhere to someone who can weld good and paying a few bucks. Yeah...how about a pic man were all wondering what the hell your talkin about because when someone says "the can" that the very last section in the exhaust. The firs section is the "Y" pipe, then the expansion pipe, then ususally a "U" shaped pipe that directs it into the can....
