what pipes you got ?
What would be a good clutch/flywheel setup?
It does appear to have tapered plug seat.
Came with Dynamite Platinum 053MR.
Also the Carb has a REX sticker on it and I don't have any venturi's.
The track I will run on most is average 1/8th scale size. Open, flowy layout. Good sized jumps but nothing insane.
Is everything on this motor the same as the 421B except the sleeve?
