What's the bore size on the M/C? You may not be pushing enough for the dual discs. It should be at least 16mm.Ellwood said:I have dual front single rear disks on a vintage 500 pounder + my 200 pound self... Stops good for an old bike but not anything to write home about. Still get a little pucker if something sneaks up on me.
Thanks, man. Yeah, it's had head work done to it. All the valve seated, heads shaved, resealed etc. Tensioner has been fiddled with, it was off when I got the motor.Tune-A-Fish said:Worked pretty good, but you aren't really gonna leave it like that... are you If you don't plan to do any motor work, I would pull the cam chain tensioner and make sure its free, I have had many that are froze and you think when you loosen the release it springs forward but actually does nadda mang... Just a heads up if you weren't already aware.
I suppose I can look at a combo of that sprocket and shimming the rear sprocket. I need to make up 11mm. The inside of the rear sprocket lines up exactly with the case. I need to figure out minimum clearance for the chain between to the sprocket and the case. Reading the KZ forums (since there are no offset rears sprockets for KZ or GPZ and this is a GPZ rear) guys shim the rear and replace the studs with longer grade 8 allen bolts. I say this assuming 11mm is too much to make up with shimming the entire rear wheel.Tune-A-Fish said:This may be spendy but correct to get to 520 and use the stock hardware:

My shaft has the threaded center, so it doesn't use the retainer. Can this sprocket still be used?cxman said:i used devins 10mm offset sprocket on my 73 cb750 to line up the mags i am using
I have an a/c in there, but it doesn't really do a lot when it's this bad. I opened the door and worked for about 30 minutes. No more than that. I really is hot as hell right now. The 520 is less bulky. It also seems easier to convert the front sprocket to 520 than the rear to 630.budlite282 said:Dayyyyyum.... Eric......your garage must be air conditioned, or you're just oblivious to heat.
It was 104 degrees out today, and in my garage, it's 119. And that's as I type this message.
Hell, I can barely stand to go to the frig out there to get a beer.
But....all in all....hope you figure out the sprockets. Just one question .....why convert to the 520 chain?

xb33bsa said:for the offset rear you can gain some by making a stacked offset out of 2 sprockets but it really requires a lathe to make it a clean lash with minimum weight.what does the rear hub use as a center for the sprocket ? if you move it 11 will it still be on the centering register ?
