Hiya, I think rear drive unit gears from other models will work. I am still trying to figure out how to get the coupler off from the front. I believe the ring and pinions will fit. I think the 37/11 from a KZ1000 ST will go in. Then you need a speedo healer. Also ZX14 headers fit and have a larger primary tube size and can give you dual muffs. Then, the ZX14 TB's fit as well when you use the matching intake manifolds. Just think of using a PC3 USB. AANND, the ZX14 camshafts goin in as well. The problem is getting the Variable Cam drive to work and a lack of Nubbie for the intake cam position sensor. I am thinking to get one made. Ooh, there is also the option of a turbo.
Tnx

With the shaft drive.....gearing changes are all but impossible.
Also, the low end grunt has been programmed out of it. To get around it, easily, you remove the secondary butterflies and add a power commander.
If you don't go with a full exhaust, you wont get the gain, up top, but the bottom end comes alive. Its really all you want. Even in stock form, its plenty. Its what you get when you try to turn this high horsepower, quick revving zx14 motor into something for touring. You can only do so much, but in ways, its what's so charming about the bike and gives it personality. Still, very rideable in stock form. You just want 1400cc's to feel like it. If you ever get the chance to really let it do its thing, look out.
