Reed valve dimensions

#1 Post by thumper580 » Tue Oct 31, 2017 5:49 pm

The yamaha yz125 reeds are 1-3/4" wide. The RZ350 reed cage opening is 1-3/4" wide from inside edge to the other inside edge. Is it ok for the reed to be flush with the cage opening????

Thought it should overlap the cage face some. Thoughts......

You nedd overlap, They have to seal, Itll leak air around the edges, Itll perform the same as when the reeds start to bend, Spitting and running crap
