Hello all, my 2001 arctic-cat 500 is lacking power.
It sputters when I gas it, and it just doesn't have any oompf anymore.
I took it to the garage for a single day, as I didn't want to spend much on it. They didn't find the problem, but here's what they did :

Changed air-filter, sparkplug,oil and filter
Cleaned carburator
adjusted valves.


What can I try next to resolve this issue?

Thanks!

 

Hey I'm having the same problem. Did you ever figure out what the problem was?

 

Mine has the same problem when I spin the tires really fast in reverse
