These cases are good for any of the non-74cc kits, but you could just open the skirt area and be good to go. I ran these with a hero a few years back and ran great took the engine apart and just went another direction. Middle bearing seems like it might need replaced from sitting, they are dusty. Buy this and maybe all the korado stuff to kill it in stock moped gp? The crank is a stock crank/rito I had moped crank works do when he was still around. I bought the welded cases off edexline.
