Counter Sprocket Spacers

Hi all, I've replaced the counter shaft sprocket (front sprocket) on my 1982 Kat 750, but it came without those wierd cushions the stockers had. Apparently the stockers are really expensive, so I guess I'll have some spacers made up. Has anyone had to do this before? What are the dimensions of the spacers?

If no one knows, I will measure it up and let y'all know what I find.
 
YMMV, when replacing the old 630 stock front sprocket with an aftermarket one, I didn't need any spacers at all other than the stock one behind the sprocket to get the chain to line up and to bolt the sprocket on. With the new 520 offset sprocket I have now, it took a 1.25 mm spacer on the front of the sprocket to get it to bolt on. So, you might want to buy a handful of the spacers and see what works for you. :)
 
Take the cushion off the old sprocket and use it as a spacer. Make sure you use the inner and outer in the right spots as it does effect spacing. This does work cause I've done it. Make sure you use the lock tab washer or you will lose the sprocket.
 
This was discussed appx 6 wks ago. Those things on the stock sprockets aren't spacers, they are noise dampeners. They don't space the sprocket out at all. The after market sprockets don't need any spacers, they are designed to fit. Don't see how you could fit the noise dapeners on an after market sprocket without drilling holes in it, and if they weren't drilled at the persice locations, they wouldn't work anyway. Check this out all you can before you go to spacing.
 
Do a search for Sunstar Sprockets, posted back in Feb. Read the whole thing, plum to the end, It's explained fully there.
 
I tried to install a sprocket without the "cushion" on my 80 L model. First I measured the distance between the crankcase and the sprocket. Took off the old sprocket and put on the new with no spacer and the sprocket was not in the same spot. Took the cushion off the old sprocket and used the inner portion as a spacer. The sprocket now lined up. On my L model for some reason they did not use a lock tab washer. It just had a nut that inverted into the cushion. Even with seventy punds or more of tourque I kept spinning off the sprocket. I bought an E model nut and lock tab washer and did not use the outer cushion so the washer bit into the splines. Tightened down the nut and bent the tab over the nut and problem solved.
