Gearing.

Post by palepainter »

I came across a 19 upper gear for the short 1/8 mile track we are racing on here in CO. It obviously loosens up the chain, but does it too much? Do I need a shorter chain? Has anyone else ran a 19/39 combination in their chain case? I am running this on a 76 Liquifire. Any input appreciated. Thanks!!

Hi Pale,

It you are dropping more than one tooth, you will probably need the shorter chain. The 21/39 combo uses a 68 pitch chain, so you will probably need a 66 pitch. Luckily, I have them, and the smaller set gear sets NOS if you need one.

I will be in NY this weekend if you need parts shipped.

Ya Joe. Will I be able to get away with just the chain change on the 19/39 combination. I have more money into finding gears, than I paid for the sled actually. :) Let me know what you need for the chain. U sent you an email.
Thanks!!
Mike

try a 40 bottom gear with it maybe it will tighten the chain enough to be ok , give you a little more gear too wade

I'd have put a 40 on it already if I had one. :) Tough to find.
