Belt drive 750E?

The why has been answered several times but yes for the fact chain drives tend to stretch more, lose power and also tend to wear out faster .
I thought about spotters also just not sure they would fit. The trash. Side is the concern, the chain guard wont be a issue i can run with out or make something for that. The pulled are what i need to figure out. The bike is going to be changed from stock anyway so just like the simple maintance for the drive system . But chains can be found daily, belts not so much

I wonder how difficult it would be to remove some of the center section of the pullies and replace with the center sections of the sprockets? It would require a good machine shop and some careful measurements to assure alignment and clearance .

I just did some looking around on Partzilla at the belt drve KZs. I wonder if Kawasaki could possibly have made it more complicated? :blink: I looked at the 440, 500, and 750 versions and each one uses unique pullies. The pulley design, especially in how they mount, is quite different. The EN500 was in production longest and most recently, so those parts may be easier to find. Evenso, one of the others may be easier to modify for your application. I hope you will post your process. This should prove interesting.

Output shaft. I was thinking the ends of the 750E & 750K/ZX750A output shafts were different, but they look very similar if not the same. The ZX750A Fr sprocket is kind of offset. not sure if that's because of the output shaft or what. ??? see JT Sprocket catalog. compare the 750E Fr to the ZX750A.

VN900 pulley. The Vulcan 900 Fr pulley appears to be similar to the 750K. Where it fits onto the output shaft, it's shaped the same & also has 13 teeth. I don't know if the inner diameter is the same, though. I also have no idea if a 750K/VN500 belt will work with a 900 pulley or vice versa. I'm thinking you'll almost have to use 750K rear pulley, assuming it will work with the 750E Rr wheel.

VN900 pulley ........ ........ 750K pulley

Tjis makes me wonder if the out put shafts are diffrent or the same between years etc..
Those dyes to make them I'd think didnt get changed every year to keep costs down and profits high

Within the real of possibility is that the 750K/ZX750A output shaft part number supersedes the 750E part number. Looking at eb photos, the output shafts appear to be the same. eyeballing may not be the best way, though. Too bad Kawasaki.com changed their diagrams & got rid of the x-ref info.

Pulley spacing. Something else to check would be the fitment of the belt. It would be good to know what the pulley center-to-center is on the 750K. then compare that to the 750E sprocket spacing. I'm not sure if a 750-Twin is bigger than a 750-4 in that regard.

If your lucky they will be the same, a direct bolt on like the 440.

In the hot rod world they have what they call a cross over manual. So parts from a chevy that fit a vet are listed, not sure in the bike world, haven't seen one anyway

That would be nice!

Partzilla has a cross-reference, but you should double-check some parts as the x-ref isn't 100% accurate.
As recently as a few years ago, Kawasaki.com had a fairly comprehensive cross-reference, including superseded part numbers, but not now. Zedder.com has the cross-reference, but I don't know if they have the supersession info.

Awesome, thank You! That will help a lot on this thing.

Unfortunately, Kawasaki.com doesn't provide that info any more.
