Hi Ed.
This is from one of my previous posts.

"The other mods to this bike are a 621cc JE piston, Web motocross grind camshaft with matching valve springs, ported head by Baisley Performance and the Cobra slip-on.
Unfortunately as I was buttoning up this installation, I noticed the main bearings had some play. So, it will have to be torn back down all the way and new mains installed.... I have really been dragging my feet on this."

I have the kickstart activated decomp hooked up so kicking it isn't any more difficult.
I don't know if I'll have to use race gas or not. I only have 30 minutes or so run time on it and have not twisted the loud handle very far yet.
Didn't have to bore the cases.

Here's a few pics of the install.

As you can see, I'm not a detailed picture taker when I'm working.
