My kit came with #410 chain, when I set up the sprocket alignment I soon realized that the stock chain is not even straight! Looking down the chain reveals that it had a twist to it and swayed left and right. So I ordered the
KMC 415H chain from Pirate Cycles. Very nice chain but I am concerned because it seems to slightly rub the engine case behind the sprocket. I read various posts about people using #41 chain as well. Is the chain rubbing behind the sprocket a concern and is there anything I should do?
Sprocket alignment is within 1/16".
