I have gotten great info from you before...I hope you get this...I have an 03 ltz 400, I have not done anything to the engine except for regular maint. since it's been new...question is, I believe my valve or cam chain is making alot of noise, do I put a new cam chain(heavy duty DID) as I have been hearing rumors or do you have any suggestions
Thanks alot, I know you know your stuff about this quad!:

 

I run the did chain in mine, its not the HD I was told you might have to do a little mods to make it work but I could be wrong on this one, I've been running the did chain for over 2 years and its still working great
