ATV question??

[silent one]

Have an 04 650 arctic cat. When new it would run around 75-80 now only 50-60. Have change belt and a few other odds and ends to try and get it back to normal. It seemed to slow down pretty drastically. Some one told the valves needed adjusting, and it has had tune-ups since. Does any one have any idea what may have caused it to slow so much? or is it normal for a belt drive to slow this drastically? Thanks for any possible help..

Check it's maintenance history & you may find some stuff was skipped. Also, taller tires may hurt the top speed.

There is no such thing as High Range from Ans 1. The Valves probably need adjusting. They will open up when new. This is a easy fix, and you should get it done. It may be faster that it was to begin with. If they back off even .001, which is thinner that a piece of hair, it will slow the bike drastically. New engines need to be adjusted just 30 days after break-in.

Has it been knocked out of "high range"??
