do any of you guys just replace your rings on your yz400s??? i wanted to know how often or what should i get my cylinder

deglazzed to or what??? thank you

Some guys have 3 years of racing on these bikes and have not needed to re-ring. It all depends on your symptoms. If you suspect your rings are starting to wear beyond spec, have a leak down test performed by someone you trust. How do you find someone to trust to do this? That's a million dollar question. Personally, I would ONLY trust myself to do it.
