    might go by the stud size. can always make the holes larder on the 50s case. think you may need to change rod also. or you got some other plans ?

    I have a gen 2 steel jug and the ports are about 20 mm off to matching the cyl ports this thing has no power at all so i was wondering if i could install the 80 cc top end.. another thing if i need a crank i dont think the id of a 202 bearing is the same as a 203 therefore the 80 crank wouldnt fit in the 203 bearing??? why change the crank? pin size diff? Thanks

    Question-Before you did you check for air leaks,chang the plug and plug wire and cap ? Most of these engines need to be broken in. Slowly there will be more power and speed. it's weird I know. but all of a sudden it all falls into place and makes you wish there was another so ou could go faster. These engines are not built for screaming more for getting you there . Good luck. Hope you get it strightened out.
