This is the best one I have found
http://oldskoolsuzuki.info/once there on the left side of the page click on "Seven-Eleven"
scroll down to "FAQ & DIY"
then click on "Frankenstein's guide to oil-cooled monsters"
There is a lot about what fits what on the GSX oil cooled motors (Gixxers, Bandits, and Katana's)
1.) Crankcases and engine covers
2.) Crankshafts
3.) Clutches
4.) Cylinder blocks/pistons
5.) Cylinder heads
6.) Gearboxes
7.) Miscellaneous stuff
The web site is real heavy on "javascript" using "frameJammer" so you can't just link to the pages directly
