Tell me about it.. I kicked myself in the ass for selling mine, after running the exact motor I sold (Go 7 port) in a 2 hour enduro race in a friends car..... And now getting back into it (yet again!!)... the go is on my short list.

I had some tuning isses that I didnt have the patience to work through (bad mental state, state series going on, being an idiot), and sold it...

It was such a strong motor for the entire 2 hours, and was pitting at 225, and came off at 240 (bone dry tank) and the end.
