The main issue is the sprocket alignment. It seems that the front and rear sprockets are around 1" out of alignment. I was thinking of just getting an offset sprocket but that seems like a large difference.
Has anyone sorted through the sprocket issue before? if so, which one did you use?
It looks like I'll have to cut and notch the frame as well for chain clearance...
Every wheel /swingarm swap is different but once you have done one or two it's pretty much the same procedure and with a
correctly centralised wheel rim up to 5.5" wide it's usually fit a 1/2 " - 3/8" or 5/8" ths offset front sprocket and then machine some material off the sprocket carrier face to bring the chain in line.
You can buy the sprockets from EBAY, APE, TALON, etc and most motorcycle drag race and performance shops like PITSTOP, SCHNITZ RACING etc etc and the spline pattern is pretty much the same small diameter "Z13" on all early kwaks and many Suzukis so it's worth looking at OEM sprockets first as these will be cheaper..
JT'S sprocket catalogue lists all OEM sprockets with diagrams and dimensions and is great for this purpose as there are many stock sprockets with various offsets and you may also find one in the F4i's 525 pitch which will save finding or making a rear in 530 that will fit the wheel.
With the z900/z1000 for example using the earlier ZX7/ZX9 5.5" rim it's a 5/8 th offset front and 8mm off the sprocket carrier and the chain just slips past the tyre and frame by a couple of mill
( Going to a 6" rim 190 tyre means notching the frame by 5mm and using a 7/8 ths offset front. )
The 650/750 frame is pretty much the same width as the 900/1000 at the pivot so you shouldn't have to notch the frame up to a 5.5" rim.
Last 650/750 frame i did used Suzuki RF600 (teapot) running gear with 160 tyre if i remember correctly and there was no frame clearance issues.
