Hey guys I’ve read everything I can find here about this bike. 2016 Kawi KFX50. A few questions for the experts.
I’ve ordered 4.5G Variator rollers. In the sticky post this was right at the recommended weight. Can anyone tell me if I should go high or low, or will this be about right. Right now the bike is stock. Hopefully now for long

Ive ordered 2 CDI boxes, both didn’t work. I’ve read about a ground wire that has to be switched. Is that the case for boxes that don’t work?

I removed the reatrictor in the exhaust but the bike kept stalling. Also purchased the Unifilter for intake. What would I need to do jetting wise for the added airflow?

Any help is very much appreciated.

Adam
