I started w/ jetting recommendations for a 280, and the settings were way off. I put a used street tire on the back wheel and took my bike to a local shop with a dyno. Dyno tuning was the best $100 spent.

There isn't a shop with a Dyno anywhere near me, do you know what Main and slow Jet you ended up with
