'76 KZ900 (ZRX1200R) Build

I don't know how a person makes supper without a machine shop in their garage!
I've used my mill and lathe as much as a circular saw during our latest remodel!
Oh, bty, THEM WHEELS BE KILLER!
Now I know I have to do a set, got the rear already in an 4"X18" and a front in 2.5"X18" but not matching.

Les,

With your mad skills and machines at your beck and call, you could just make hubs from scratch....! What do you mean the hoops don't match?

Cory

Call me crazy,most people do anyway! :woohoo:
But I was looking at your upgraded charging system and it suddenly clicked into my head,why couldn't you make a pulley to run off the output sprocket?
Guys have been running alternators for years off the 3rd members of street rods,So why couldn't an evil sprocket building genius like Leon create something like that?
And yes I remembered my meds today! :woohoo: :woohoo:

One wheel is a sun and the other is an Excell. Close enough but I know how I am, it'l drive me crazy every time I look at it. :blink:

I think there are two issues with running off the drive. Inconsistency of the drive rpm and no alternator output when riding slow or idle. Alternator have a window of charging efficiency and with the RPM changes post gearbox, that would be difficult to get consistent charging, but maybe not. It might allow for mounting more toward the center of the bike though...

I have seen Harley Custom bike do this by coming off a jack shaft off the primary drive and NASCAR run alternators off the rear differential, so it might be feasible....

Cory

I'd like to get one of those set-ups that run off the end of the crank but they use an alt. off a suzuki (I think). Have seen them on a few older Suk's but only one KZ. Takes stress off end of crank. Like on this bike...

That is interesting as I have never seen a kit to do that. Every one I have seen were custom made. I am using an automotive alternator.

from the net.

Here's a version on a Suzuki....

This one is a streetbike that runs mid-9's...

Who makes the kits?

Cory

Wish I knew...I've only heard of one guy who USED to make these many years ago. Haven't found anyone other then this guy. I heard the belt and pulley they use is from a belt driven fuel pump used for injection units but other then that, I'm not sure. If you have somewhere you can have parts made you could make your own setup though.
