2006 CRF450r valve replacemnet

Recommended Posts

I'm replacing my intake and exhaust valves. Should I replace everything, retainers, collars, guides? Or just the valves and springs? Thank you!

Unless you are an experienced mechanic (and since you ask, I'd guess not) I would. 

If the guides have no radial movement, they would not need to be replaced, but that is rare. Check the seats for wear as well. Steel retainers and collars last well but aluminum and titanium retainers have to be replaced due to life cycle and will fatigue and fail if not. Even the steel parts need to be checked for wear and show it most of the time. When in doubt, throw it out! Cheaper to replace now than to drop a valve.
