B&w 250 crankshaft problem - chain sprocket needed
« on: May 28, 2012, 01:28:38 PM »
Hi,
I have a problem with changing crankshaft bearings on B&W 250. Actually broke chain sprocket. Any idea where I can find new/used part online, complete assembly of crankshaft is not option, only lower chain sprocket.
Thanks

For used parts search Ebay. Look for any used Mc./Scoot. part, and then follow the link to sellers store. Most of the used sellers on Ebay are actually salvage yards parting out bikes. I am under the impression the crank is one machined piece. I do not know that the gear is separate.

I v' done a little inquiry, if i wanted to remove sprockets i should have used liquid nitrogen and heather. I have not tried to remove bearings with classic bearing remover. I managed to remove upper sprocket but lower, the nightmare begun :) Difficulty to find part goes in favor to the theory that Kymco really is a good engine. Anyway thanks for the advice, if I find the solution, will post.

I just rebuilt a Bet Win sh50ca 250 engine. I have the old crankshaft if you still need the sprocket.

I just did a 300cc upgrade and I also have the stock cam and sprocket available. Came off my own scooter with 6k miles on it.
