Would a balanced crank help me get above 8600 rpm?

The first part of the letter is behind the cheek. Zeda 80Another new Conrod. DA-80 Spec's would be nice.

That's different from the ones I got from them. The one in the pic. abv. on the right is what I got as stock Zeda, and the one on the left is a balanced welded Zeda crank.

I just noticed that the 3rd holes are not through holes. That's from a case reed but thought it would be the same as the other zms balanced cranks minus the jb weld.

and the jb is to help keep case volume down?

After looking at some random dyno charts of these motors I'm no longer worried about how high it could potentially rev, power seems to peak around 7k. Instead I'll shift my focus over to improving the intake, mainly getting a cnc intake and an VM18 carb. This bike already rockets from 20 to 36 mph, I'm excited to see what a proper carb/intake can make it do. Despite Robert's dubiousness the motor I received from him is rock solid and makes great power compared to the ebay special I started out with.

Yeah. Did it to the crank I balanced as well.
