Be patient with Frank, he may sometimes be a little slow in responding to emails. As I understand it, he's "retired" and certainly deserves to enjoy life's other distractions. Most times I have corresponded with him via email, he has been very prompt and courteous. Super guy to deal with.

As for your SU-31, well..., my Homie 30cc on CH Synchrospark manages around 8500rpm with a 16x8 MA and weighs around 3 lbs 10 Oz. with an aluminum mounting plate and B&B muffler. This was after only 16 Oz. of gasoline run through it, so the engine is still very green. I am hoping to get over 9000rpm with the same 16x8 MA once it breaks in some more. This might help you draw your own conclusions.
