Hey Lee,

I just put a stock Mugen clutch on it for the break-in, with 3 .95 springs, I'd like to try a BUKU clutch next. I've got the M2C four shoe alum flywheel adjustable weight on two of my other engines, a Werks B6 pro and a Werks B2.
After she's fully broken-in, I may have to try a Werks carb and see if I notice any difference.

After trying the Werks 2013 pipe tomorrow, I also want to try using a progressive set of clutch springs, I'll start with a .9, then a .95, and then a 1.0. Trying to achieve a clutch that performs like the BUKU clutch.

BTW, I used a qt. of Powermaster Golden Break-in fuel, then the last three tanks I mixed in a third of Powermaster 30%, then half, then two thirds. It took about a little over a gallon to lose the cold pinch.
Cheers
Brian
