I finally took the Puma out on the highway for a run. Wow, that motor makes some power, and i don't even have it dialed in yet! I have the carbs synced pretty well and have the fuel/air mixture close. What I'm really going to have to play with is timing. I have it set at 5 deg BTDC at idle (30 deg @ 3500 rpm), and it ran nice, but I'm going to add 2-3 deg advance and see how that works out. Then it's back to mixture adjustments again...The twin exhaust looks awesome too.
