hello, i'm not sure if anyone has any experience with the gen II 48cc kits since they werent made available due to the import ban, but i just received one about an hour ago and i had a question or two i want to put out there. this is the engine that has the head with the angled spark plug inlet, larger bearing, and needle bearing on the wrist pin. should i break in the engine any differently since it supposedly has a piston sleeve made out of a stronger metal than the older engines? anyone have any tips or heads up on anything i should watch out for? and if you're wondering, the kit is pretty decent. i picked it up on ebay from "boygofast". good price too, $192 shipped. i'm gonna swap out my old engine and hopefully get the gen II fired up this weekend. but first, let me know if anyone has any tips. thank you.
