I got my adapter from ScooterCraft (RIP dudes!). I had to machine it (bore the ID) to make it fit. Quick and easy on my friend's lathe... if he didn't let me use all his machines when I needed them, this project wouldn't have made it.
I have these posted on Scooter Invasion also, but wanted to share the dyno chart here too.


The second run (green line) was darned close to 90MPH!
Still have a good bit of tuning to do, and a few more parts to get for the bike. It's going to be a few weeks before I get going on it seriously again.
