First I'd put in a piston of about 10:1-10.5-1. Powroll has one or maybe a Wiseco, not sure what ratio the Wiseco is.
Next get the Powroll torque cam and to run with the stroked crank that you already have. They compliment each other and deliver lots of nice smooth power on the bottom and mid range. Be sure and run the auto decompressor! Starts and idles just as well as stock. Powroll did their homework on this combo, you don't have to rev like a stocker. Much easier to ride and also easier on the engine. Not a top end mx engine , but for the wife and kids with basic riding skills would be great. Put it together correctly, take care of it and it will be VERY reliable!
