I have a 1998 Yamaha Wolverine with some power issues and I was told to check the spark arrestor. I am new at this so can some please give me a tip on how to find and check this!

 

its in the end of the muffler/tailpipe ther should be a bolt or more holding it in. might have to pry/wiggle it out then just clean it off and reinstall .
but it would have to be severly pluged to cause power problems..

 

Whiley, thanks for you help! I bought this use and she has been driven pretty hard so I am just going through her trying to get her to stand tall again.
