So I'm headed to the dyno this saturday and the guy that runs it is kinda new. He's only done a handful of EFI bikes. He's agreed to let me be a apart of the tuning so we get it spot on. I've herd there are some tricks to getting the FCI to shine down low as well as up top. Is there a target AFR to look for in a certain RPM?

Any tips or trick would be greatly appreciated!

It turned out being a long, hot, and expensive day. Second dyno pull the flywheel came off at redline.

I'll be headed back to the same person as soon as I get my cam degree checked.

You guys planning on doing it this weekend? I'd like a few things to know about it too...cause unless some work comes up on that day I'm gonna get mine dynoed up in N. Florida...3 hours away but I think it'll be worth it to see what my build really feels like properly tuned.
