That was a concern with rpms for the pump. Once I have it all together enough to know my rpm range and have a pump I'll be able to know more. I Talked about dropping the lighting coil to save drag on the flywheel and run the pump on the battery. But with front sprocket options seeming like 0 I don't really want to run at too high rpm before machining my trans support. Pros and cons, shifting a little heer a little there. I'll cross that bridge when I get to it but it's a ways off in the distance.
