Hey thanks allot everyone I really appreciate it. And Anderkart what you said is absolutely right and makes sense. I don't have a tach because they are too expensive even thought I already dumped a boat load of money in my engine it would make sense to buy a tach that way I don't blow it up...
Ok first timer on the site. I just hopped a predator 212cc.
Milled head to the max I think .65 or something. Flat top piston. Arc rod. Biggest cam they make. 32 mm intake valve. Tilley carb on methanol. Billet flywheel. Were riding on a dirt oval we made at our house about a 1/8 mile maybe...
