Hi all! I just found this great site and registered. I ride a '92 ZX-11 C3 and need to replace transmission gears, forks, drum. Would a "D' transmission be an upgrade? ZZR tranny, ZRX 5 speed. Are any of these swaps possible? Thoughts?
btw that d model with the 12r forks and 7r swinger looks sweeet!
p.s. glad to be here!

Ping Claude, he can tell you exactly what is required to do the
D to C trans mod.

A transmission from a D model is a perfect fit into a C's engine. But you need to know those two point:

1-you must swap the assembled shafts as a whole; not individual part or gears over C's shafts or vice-versa.

2- You need to use a D's front sprocket along with a D's output shaft (or, of course, a C's front sprocket along with a C's output shaft). D's output shaft is longer than C's and both sprockets are made accordingly to fit on their respective output shafts.

If you respect those points, it's a direct and perfect bolt-on.

Oh and BTW, what's your avatar? Is this a 750 H2 triple engine into a ZX11C (or ZZ-R1200 or other) frame? More pics or infos would be nice (I'm just curious).

Thanks for the info Claude and Ozzy. BTW my avatar is my 4th overbore H2 engine mocked into my 1990 ZX-7. It's a long term project. Not completed yet. Waiting on $$$. I need to find a more or less permanent host to upload pix to, as in dogpile etc.
