My engine seems to knock a little bit, similiar to the way my 2001 warrior did. IS this normal?

 

hmm...it depends how much...mine did when i had my 04 660...i think i could be a little normal but to much is probably not good...ive had so many prpbs with my 660 i got rid of it..

 

my o4 660 knocks a little bit when warming up. after that it knocks slightly. it must be a raptor thing

 

I hope you guys are speaking of valve clearance noise.

 

Thanks for taking the time to reply guys, and yes to me it sounds like valves clearance noise!

 

Mine was making that sound and it was the valve clearence. 75 dollers at the shop not too bad.

 

What do you mean by "knock?" my engine doesnt knock at all...

 

i mean a little valve knock when warming up. after it's warmed up it quits. but the engine does make some noise from valves. normal noise though nothing unusually loud.

 

it could be the gas octane your running i run nothing but premeium in my tanks for quads then you'll know for a fact it isnt that no matter what people say the higher the octane the cleaner it'll run am/pm gas sucks it'll cause your engine to knock some what...
