Ok folks - just bought sled (first time skidoo owner, longtime fan). It is totally dead on the low end has very slow throttle response. New 6 gal of no ethanol prem fuel on top of 1/4 tank of old fuel with stabil in it. Bone stock with only 500 mi. No comparison (sad to say) to bud"s 08 M8. what does this unit need?? Do SLP single pipes make a big difference? Any ideas? Help...
I own 2 07 800r's, one a 144 and an X with a 159.
the 144 is totally stock except for a can, and the sled rips. good strong throttle response all the way, redlines around 8200.
the X same deal good throttle response, redline between 82-8300. these sleds pull well when runnin right
Doesn't sound like your problem is with bad gas, I never use any Stabalize in my fuel.
So what to check, carbs yeah, but if it starts well and isn't tryin to flood out on ya when ya get on it I'd look at a few other things first.
Clutch adjustment is a big deal, as is well maintained clutches. Take em off and service them and if there stock, read up on adjustment for proper RPM's. it's pretty simple stuff.
Also check yer RAVE valves for proper operation. If they're not funtioning right, power will suffer through out the band.
If both of the above check out, i'd follow thru with checkin out your carbs.
Reed valves, will usually make it a hard starter, especially when it is warm. then you'll notice it just doesn't run well at low and mid range, but when get above 1/3-1/2 throttle she'll fly.
Finally a can and y pipe is a nice addition will make it a bit more responsive. And if nothin else drops a good 10lbs off the front of your sled and gives you some more storage room.
Good Luck,
LA
