Hey guys, my 04 raptor 660r is having a issue revving up.

I cant hit the full powerband on the quad, seems like 1/2 - 3/4 throttle it starts cutting in and out like its hitting the rev limiter, except it sound mor like a On-Off-on Bogging sound. So i cant pull a gear all the way cuz it will bog and start cutting in and out, i usually have to lug and cut short on acceleration at 3/4 then shift again.

I just cleaned the dirty air filter thinking it would fix it, its crisp clean... and didnt change. im thinkin maybe carbs need rebuilding? or possibly new spark plug?

idk...any help would be greatly appreciated.

and if you guys are wondering this is the quad, Heres a Revival thread:

It wasnt those. ANd I tried the search button...For hours. DIDNT FIND ANYTHING. SO i opened a thread for people who have experianced it b4 to post in here t here knowledge.


Anyways. I fixed it, I tore the carbs apart and Cleaned the heck out of every cranny. I belive it fixed the problem. I didnt go to far up in the RPMS on my test run.. But i think its cleared. Ran out of gas so had to cut the Test run short.

eBay or Amazon cheap Chinese carbs? That's usually the problem. They're poor substitutes for the originals.

Or it could simply be mods that require re-jetting.
