I'm running a stock MBK CDI on my 50v and I recently swapped out the stock CDI box for a Yamaha Jog 90 CDI box. It seems to be running just fine, but seeing that I'm in MN and we're in the middle of a shitty blizzard I cant really try it out other then start it up in my garage to verify that it runs.
I'm just wondering if anyone else is running one of these and if it's really unlimited revs.
Here's my wiring diagram
