External Alternator?

NakedFun wrote: It looks badazz and would open up the possibilities for increased charging output, but also looks like it would rip your pants right off if you moved your leg wrong.... pantless riding = police ticket.

Anyway, I like the additional cornering clearance and I am a sucker for a gilmer drive belt, but wouldn't it be easier to just reduce your electrical loads such as HID headlight, LED signals, etc?

That's a good point about the pant leg getting caught in the belt. I think I would rig a cover :huh: I have always thought the stator on the KZ was a bit cumbersome. But that was the design of that era. But I have wondered if there was a low profile aftermarket stator/cover combination out there? Maybe even smaller in diameter. But sill having the an equal output using more modern components.

One thing I didnt think about initially is the weight removed from the end of your crankshaft. By using aluminum gears and a small alternator, you will have an engine which revs faster.
Less reciprocating mass on the end of your crank. Similar to a total loss ignition on a jet ski. FAST rev. Hindsight, it would be a performance mod.

Wow, just got out of work and saw all of the responses. Thanks for posting the pic of the rest of the bike, I didn't think about it when I posted the topic. I want this bike to be unique but functional (at least for short stints) and a guard would be in place (maybe something like a clear dry clutch cover).

Here's one i made for my Z1R with belt guard.
Used everyday for 15 years and still going strong on the original belt.
Simpler wiring too as the reg/rec is already in the alt.

zed1015,
is there any way we could persuade you to tell us which alternator you used and what ratio the pulley set is and,basically tell us all how to do it and show us pictures and write up an instructional article and and and :woohoo: !

it looks great,super sanitary and highly functional.

which is what we have grown to expect from all of your builds.

speaking of which how is the zephyr frame big motor project going?

It's a ZX9R alt running at just less than engine speed 40/44 tooth pulleys.
Had to do away with the starter clutch to keep every thing slim and simple.
As for the ZEPH1R project as i have cunningly named it here's a recent pic.
Sorry for the thread hijack.

I like it, I love it!!! You wouldn't still happen to have the blue prints around for that plate and brackets would you?

It is just superb. I really like it. This tricks really help me lot and I make a successful combination here.
