Ryan Weddle Posted July 4, 2020 I'm putting motor back together after installing new wiseco piston on my 08' RMZ250. The problem I'm having is i cant get the exhaust side cam chain guide to set in correctly so that the exhaust side cam sits flush. what am I possibly doing wrong?

Pmv17 Posted July 4, 2020 I believe there is a dowel on the bottom of the guide and a notch cut out in the bottom end that the guide sort of snaps into, make sure it’s hooked in down there good. Also be sure your valve shims are sitting on the valve springs correctly so that your buckets are sitting down all the way. 2 Share this post Link to post Share on other sites
