I need a head for my '97 750 Katana. I have 2 '91/'92 GSXR750 parts motors. Can I use my Katana cases/crank/connecting rods with a Gixxer head? Would I need the Gixxer cylinders/pistons or the stock Katana parts. And would I use the GSXR cams with the Katana sprockets? Is this even possible or am I . I searched and found references to using '86/'87 GSXR parts on the Kat motor, but not the later years. Thanks in advance for any input.

no, the pre 98 Katana 750 is the short stroke "slingshot" engine 44.72mm. the GSXR 750 91-92 are the longer stroke 48.7mm. 86-87 parts are about the same stuff that's in Katana engines, upgrades come with the 88-89 GSXR 750, that's the years the GSXR was a "slingshot" 44.7mm, tooLast edited by arsenic; 02-02-2009, 02:22 AM.

What it actually refers to is the carbs, look it up instead of guessing fellaRenthals & twin spots do not make a streetfighter !

I just had a chance to look at my parts motors. Both of the gsxr motors have 13 Fins and are stamped 749cc on the cylinders. One gixxer has screw type valves in the head, and the other has shim type valves. One of those is mismatched, correct? The Katana motor has 11 fins and is stamped 748cc.
Both gsxr cases have serial numbers that start with R716. Is the correct head for the cylinders the shim type?
