Put the new powervalve in last night. Havent had time to really testdrive it yet, took a short ride. Seems to work better.
But I do think I would need little more acc pump squirt in the primary. Since I must up the rpm just a little before it gets responsive.
What do I start with, there are different cams and other nozzels as I understand?

First make sure the pump arm has the slack taken out of it, adjust as needed. Usually, the cam only changes the duration, so you're probably better off going right to changing squirters. It's probably like a 31 in there now, try jumping to a 35, see how that works.

Idle mixture/circuit plays a big part in off-idle transition, so need to make sure your throttle blades are adjusted properly and the mixture is good.

Another item you may want to look at is the needle and seats. I've found the ones they ship with are a little small, and always swap them with like .120s or .130s.

Sounds like you're getting closer, keep at it!

Thanks.
Will see if I can get some other squirters and try that.
