there is a circular scratch on my drive face, and one thing if i kick start. it won't contact to the driven gear,my driven gear is new.and if kick start the kick start arm won't go back to it proper position.if i luckily start it it was a lot of noise inside the left crankcase cover,i don't how to solve this pls help

any comment pls

Greetings:

Is the crankshaft moving around in there? Stripped threads on the drive end?

yes the crankshaft is moving around,where is the threads on the drive end?is that the drive gear?

Greetings:

You had me at "...yes the crankshaft is moving around". The crank shouldn't move - at all. I was referring to the threads on the crank end with that big 17mm nut that holds the outer pulley in place, but if the crank is moving the bearings need attention. Split the crankcase and evaluate.

the drive end is not stripped,any ministroker that you know that No need to modify my crankcase just bolt and go,and what size?

Greetings:

If you want a reliable, long-lasting daily driver, get a new Honda crankshaft or try to find a Malossi Stock-Stroke shaft. If you want to experiment with port timing, decking the cylinder and take a guess at the optimum compression ratio, get a Ruima 44.1. Just be prepared for the possibility that you may someday need to push it home if you opt for Taiwanese parts..

thanks alot for the info. i have a honda elite af16e i am thinking to put that crankshaft on my sym dd50 crankcase,is that exact fit there.

if i have to premix and put oil plug what will i do to the vaccum hose connecting to the nipple port beside the starter i have sym dd they use fuel pump so do i need to shut down/plug also that vacuum hose and plug the nipple port. thanks
