Hi I have a 2005 Ski Doo SDI 600 it has been backfiring a lot. I always hear people say the sdi's are known to do this. I am running br8ecs plugs and the plugs are definitely fouled, should I change to br9ecs plugs? I've checked in take boots they look fine no cracks. The sled idles fine but...

I've got an 03 Rev 600HO that I had removed the engine to replace the crank seals (one popped out) Well anyway, I got it together and if I start it without the airbox on it runs and idles great but once I put the air box on it will start hard and when it does its like running on one cylinder and...

Posting for a friend. 2015 mxz x-rs 600 etex. Bogg/delay when first taking off then takes off fine. Barely moves during warm up. Intermittent misfire/pop around 1/4 throttle only. 4300 miles on chassis About 400 on new motor. Motor still has warranty from dealer that rebuilt it.

Help, 2011 600 etc, pull start only Ran rough, changed plugs at 11,000km. Ran perfect for 200k and started rough again, almost as if one one cylinder. Both plugs look black and dirty once out, will not idle but will keep running if held at 2500 rpm. Replaced fuel pump strainer just because...

hey there! I happen to have a real problem on my 2010 renegade 800r ptek. the problem is that the sled seems to miss some spark on one cylinder(clutch side). When I go WOT chek engine comes ON and after a scan at BRP its the knock sensor. When I put it in reverse, the problem is worse. Its hard...

hello. i just picked up a 2006 600sdi with a fresh motor. on cold start and up to operating temperature the sled backfires and hesitates on acceleration. seems ok after motor is @ 100 f. checked coolant and air temp sensors and all read proper ohms for temp. fuel pressure is @58 psi and battery...

I have just rebuilt my 2003 skidoo rev 600 HO 3 days ago ( 140 psi both sides ) and i went to do my 3rd heat cycle and its been running like (excuse my language) complete $&@$ Its been backfiring on start up and it idles very low but i hear the 2 beeps on start up. I tried starting it again and...

I have a ski doo 440/800 mod and when I pull it over it backfires and it takes over 10 pulls to get it to start. I don't know what's going on. It also has a new top end so it has lots of compression. Jetting? Reeds? Something?

Hey Guys, New to snowmobiling this year. Bought a 2005 Summit 800 with roughly 2500 miles on it and loving it so far! However, I took it out last friday and it was running just fine. Went to start it up sunday morning, started fine. Started it again sunday afternoon but i snapped the choke...
