I have a new wiseco forged piston 89.50 and I measured the ring end gap and it was .031"
The specs for Honda say .011 to .020"
Is it different since it is a forged piston?
I need to throw this back together so I can ride tomorrow!
Help!!
Ring end gap too big, should I ride it?

A lot of testing has been done on this.
Your right... Too little... Major issue.
To much??? Not so much.
I'd like to see it a bit better then yours but I have certainly seen a lot worse..
A VERY GENERAL rule of thumb is .004-.005" per one inch of bore for normally aspirated engines. .006-.007" per one inch of bore for boosted applications.
89.5mm x .03937 x .004" = .014" ring end gap or whatever..

The four stroke engine: That's one stroke for producing power and three for wearing the engine out.
