JT Front Sprocket Question

Jim Moore · June 26th, 2012, 06:14 AM

Folks,

I just got a chain and sprockets for my 98. I want to make sure I put this thing on correctly. The JT front sprocket has a built-in spacer on one side, and is flat on the other side. The writing is on the side with the spacer. My first thought is that the spacer goes on the inside, but typically the writing on a sprocket goes on the outside. I'm about 99% sure I'm going to put the spacer (and writing) on the inside, but I thought I'd check with you guys first.

Thanks,

dont forget to put on a new lock washer or safetywire the nut

Thanks. I haven't taken mine off yet, but that looks like a different set up from the pre-gen.

No lock washers for the pregen. Just two small 6mm bolts.
I think the torque spec for those bolts is somewhere around 87 in-lbs.

10 nm according to the other site. Not too much.

Except there are no provisions for safety wire. Now if you are talking replacing the stock hardware with drilled head fasteners, that is another story.

most bikes dont come with holes for safety wire or predrilled bolts. but thats why man invented the drill

Thanks for the info guys. I don't think I'm gonna drill them out and safety wire them, but I think I'm gonna use some blue locktite. Any reason not to?
