Damn, blue. The engine is less than a week old.

nothing wrong with it..

I know, I only have a half gallon on it. But as a racer, you want more.

blue is faster

I want smoother, I'm running the 8mm restrictor but thinking of going to a 7mm or a 6.5mm.

what pipe?

OS2050 is smoooooth

JP-3. I find myself only using 1/8th to 1/4 throttle on most of the track. It's managible but if I could pull a little more power away from it. I'm going to try some .9 clutch springs. I'm using 1.0 now.
