Hi, well, ok step two in the conquering of the "chain slappin' blues". After I once started building these bikes, I began to use KMC HD cruiser bike chain instead of whatever was in the kits.

Sadly, on about my 8th or 10th engine SpitFire had changed to the bigger, dumber, heavier chains. I revolted, and returned to the Bicycle Chain. These can be overcome with KMC's BMX chain, tho the pitch is a wee bit different.

Here a dremel, with a diamond bit is your best friend, work out all the burrs, sharp edges, reshape the teeth as needed, AND you should run the chain thru, over and over, refineing your teeth's shape, till the chain does not try to "climb" the sprocket, once this is done we can proceed to improve the rest of the system.

Also know, that the "shoulder" of the sprocket sometimes needs some relieving, AND that your master link too many times does not have the DOGBONE shape, and you either need to relieve that shoulder, or "dogbone" that master link. Taking care of this will stop many unexplained chain derailing, snapping, or blowing the master link episodes, and maybe long walks home?

I NEVER use the kit chain, they must be made of some metal version of silly putty.

Sooo, replace your chain, adjust it with the T-shirts, (With your carb as LEVEL as possible).

AFTER you replace your chains, we will get on with step 3 of the "Chain Slappin Blues".

Are ya with me?

Mike
