2016 YZ250 POWER VALVE
« on: June 05, 2017, 09:04:41 AM »
Why dose the tip break off the end of the center power valve? I've had this happen a few times over the last 10 years. The crank went this weekend when pulling the engine apart I see the power valve is broken again. The broken piece worked it's way under the linkage and wouldn't let it close all the way. Is there a fix for this? Two things that really need to be updated on the the 2 stroke the power valve and lower pipe mount.

The tip of which piece?
