I've got an 03 grizzly 660 that I put a set of snorkels on and now the bike isn't running like it use to. I snorkeled just the belt box and took it out to test the snorkels and they worked but the top end isn't like it use to be it use to run like 50+ mph now its topping out at like 30mph. the bike is idling fine and has plenty of torque it gets to 30 like it use to but won't go past it. could my clutch be shot?
snorkling the tranny should not have any effect on the performance of the bike. dumb question but is your tranny maybe stuck in low? I think most utes top out 25-30mph in low range.
Are you still having this problem?
BUMP STILL HAVING PROBLEM ANY SUGGESTIONS...NO NOT STUCK IN LO
maybe jetting the carburetor? worth a try.
take the snorkel off.. what happens?
