Sprocket carrier question

[arcturius]

I searched, and could not come up with the answer I need in any of the existing threads. I'm trying to fit a '92 Katana wheel into the stock swingarm of my '79 1000E with a 530 x-ring chain, and actually have everything line up properly. As it stands, I need to bring the rear sprocket in 15/32" toward the wheel to make the chain straight. I already have the sprocket flipped around to offset inward.

Before I do something stupid: i.e. unnecessary machining of my carrier, does anyone know of a 5-lug carrier that is narrower than the ones found on a '92 katana 750? I haven't found a 500E to measure, and it looks like the one on my '86 GSXR is the same, or possibly wider than the kat one.

If someone else better at searching can point me to the thread I overlooked, that would be awesome, too.

For such a small misalignment its probably easier & cheaper to space the front sprocket out by the required amount

Spacer

I have done the Kosman 5/8 off set you had to remove reshape reweld the area of the frame for chain clearence . I would have too see the 3/8 off set . I would go with a custom made spacer to move the rear sprocket out and small one for the front . it would look like double lipped spacer . One lip for the carrier one for th sprocket too ride on . any machine shop could handle that .

I would, except I can only gain about 1/4" without going to an offset sprocket, and the offset sprocket would have the chain fouling the shock before I could gain enough.

I'll probably just take 1/8" off the carrier, and another 1/16-3/32" off the back of the sprocket (it's pretty beefy) when I can beg use of a big lathe, and space my standard front sprocket out as far as it will go. I was just hoping there might be a different carrier that might do the work for me, since the current one already holds the chain about 3/4" out from the tire.

Thanks for the responses.

Unfortunately I need to move the chain _in_, so that won't work.

I suppose I could try to find a sprocket made for a carrier larger in diameter than the one I have, and make a plate to mount to the existing carrier and bolt the sprocket to the back of that, but that's a bit more involved than it probably needs to be.

Do some more measuring. Use a straight edge or a laser pointer. I'd be surprised if the 3/8 offset sprocket did not get you the clearance you need.

I must be blind...I'm not seeing offset rear sprockets at the kosman site.

I guess it doesn't matter either way, I've borrowed some lathe time tonight already, so I'll get the problem solved that way.
