How to figure proper amount of offset on sprockets

Hey cory, i sent you pm.

Square up rear wheel and run a straightedge across rear sprocket to an existing stock front sprocket and measure the space between the 2.
Theres only so many offsets available so you need to pick the closest and build around it

Thats excatly how i did it. And i got right at a inch to the outside edge of the front sprocket. Then just subtracted the width of the sprocket. The wheel is off center some but it looks good where its at.

dont ferget to releave a little of your sprocket cover where the chain passes through or it will rub sound like heck

Ya ill defitently have to look at that. I woulda forgot about it. Also i will be running a 630 chain and sprocket.

Id center the wheel up first then then use the straightedge on the sprocket to figure out the rest,If you need to offset your wheel to make the chain fit Id look for a smaller wheel myself anyway :laugh:

I have a feeling iam gonna need all the tire i can get lol. But i remember people talking on here before about leaving the tire off center and just lining up the sprockets. I think thats what i am gonna try.

I know of a certain stock looking red 78 kz1000 in Omaha ne with a chrome kerker running a skinny ass 110-18 rear tire connected to a lock up clutch/36 flat slides and a plain label bigblock with a 1385 and a really good cylinder head that has no problem putting the hurts on anything stupid enough to want to play with it! :woohoo:

Ya theres some bad zs around. Ive always wanted a big block so its killing me to get this finished up. Gotta pick up the finished block and pistons saturday. I cant wait. Got my lock up clutch all finished including polished cover and sight glass.

When you get a chance can you measure the height inside your lock up cover versus stock cover?
Thanks!

I have put the cover on already. But i can remove it tomorrow and measure it for you.

WHY?

I mean even if it is just a show bike that you will never ride it's supposed to be functional...

Don't you think?
