Harry?????
I think it is lean? does it come down when you bump on the choke?

 

[simon jones]

before my sled reved at 1500, i put my silencer 2 months ago and i didn't have anny problems, but yesterday my sled has reving at 3000 and more all day...it was almost going without pressing the trottle.

was there a big difference in temps from your last ride to when you put the silencer on?

 

[simon jones]

no..it just started doing that yesterday

sounds like a lean high idle to me

Whats the fix ?

try opening up your fuel screws 1/4 turn. Obviously, also check your throttle cable tension and idle adjustment on the carb rack.

flip your choke for a second when the idle hangs if that fixes it, a quick fix would be once the sled has idled down turn your idle screw out until the rpms are running around 1400. some guys adjust the fuel screws, but this will work and it changes constantly with the temp on mine.
