THanks guys. Again, I'm at sea level. The engine was build by JD Racing (I'm trying to find their website). Also, I have FMF Gnarly New Banshee Pipes and Silencers on the bike. I will switch to PWK's, and stick with the thumb throttle. I wish I had more stat's on the engine to help with, but I do know its bored .40 over, and I am running smaller domes in the head. Right now, it runs like crap, really rich, and despite my best efforts I can't get the carbs to synch.
Also, and I hope this isn't a dumb question. What ratio fuel do you guys run?
