pic messages on my phone will cost alot, so i did some heavy searching and it looks to be a 25.4cc and from what i read, this is the one to have! can anyone tell me how to measure the threads on the crank, plus i need an intake along with a muffler and prop hub. i think making my own mounting plate will be a breeze, just dont know if i want to do a rail mount or use the back plate. is one way better than the other?
