    Hey guys chain just jumped and jammed up my rear tire and broke the chain, now im looking for a upgrade...I have the cheap china ebay engine kit. But i upgraded the rear hub assembly to a 44T hub adapter sprocket. HERE is the link to the sprocket. What is the best chain you can get? i was reading up on and it seems most ppl are using a 41 roller chain...this tuff enough? Need to get this beast up n running again ASAP as its my only mans of transportation.

    Some of those adapter sprockets have very wide tips on their teeth - I grind just the tips thinner for about 1/8 to 1/4 of the very tops so they will find the gaps in the chain more easily. A belt sander or file will also work as well as my grinder.

    yes, sides of the tips - you want the tips to find the gap in the link between the side plates of the chain

    A really good and economical upgrade is the KMC 415H bmx chain.

    I have on on my race bike and it's held up under extreme conditions with no problems.
