The adapter base and wiring are the magic of your conversion, so if you can source a good one and swap over the base, wiring and possibly the exterior (if yours was dolled up), that sounds like the path of least resistance (har har).

Does anyone know if the two ZX alternators are interchangeable as far as the adapter and mounting plate.

I have the 21001-1115 that has a bad voltage regulator and stature.

That model seems to be more expensive than the 21001-1104 (round end) I think the it is for the zx7 and 750.

Contrary to what has been reported, they are not readily available on Ebay for $50. More like $150. This still is not bad, but I would like to know what my options are if there are any.

Tim's and J.R. both sell these things, I would consider asking either of these guys for help or parts. J.R. has updated the design, might not like the idea of working on an older one, but might not care too. He's CBX-tras on this site, and I think his contact info was in the first post of this thread. Why not ping him? He's a good guy.

So I broke down and purchase another used zx9 alternator off eBay for 100. We will see how it works out

Are these still available? If so, which of the two has the smaller diameter and which one is sticking out less?

Thanks

I'd like to add to the content about the conversions since the information seemed a little dated.

FYI, along with my automotive wiring business (street rods and drag cars) I also teach automotive electrical at a local college and have been producing CBX alternator conversions for about seven years now under my company name "CBX-tras LLC". Additionally, I service CBXs and 1100Fs and I'm a member of a team that races at Bonneville. (Yes, we've set records).

The alternator conversions made today are of higher quality than those that Stefan Jung produced years ago and I don't believe Stefan has produced any in the last 5 years. His units were functional but lacked finesse. The adapter plate appeared to be cut-out on a band saw, the splash shield was screwed on and sealed with silicone and the wire harness was spliced onto the 2 existing Kawasaki wires. I thank Stefan for initiating the idea but, I saw a better way.
Insidentially, when I decided to produce these conversions, it was my intent to utilize new alternators purchased from Denso. However, these alternators are exclusive to Kawasaki since they paid for the tooling and no one else can buy them. So, used alternator cores must be procured to build the complete conversion. I refurbish every one myself to keep the costs down. Although deemed expensive, my complete "plug and play" kits are still cheaper than buying a new alternator from the Kawasaki dealer.

The one thing I do offer is a Do it Yourself kit to help keep the costs down. No one else does this.
You supply the Kawasaki/Denso alternator, I sell you everything you need to complete the kit.

My prices haven't changed since June of 2010 making mine the most economical and are the finest available.

The benefits are: Instant charging (better starting, the ignition works better, the lights are brighter)
*Direct "Silent Drive" coupler - no plates to slip
*The stock rectifier can be removed from the bike (self-contained )
*The brushes won't wear nearly as fast due to the better design of the unit Output is about 400 watts (@ 13.2 VDC, ~30 Amps)
I sell:
Complete conversions in Black - $600
Complete conversions Ceramic - $650
Do-it-Yourself Kit (you supply Denso alternator) - $325 (I need to know the model of Denso Alternator you have)
Finish-it-yourself (you paint/plate/polish as desired) - $500 (Black or ribbed version, supply varies) All plus shipping.
Included with every kit is:
*CNC machined adapter plate with internal splash shield Custom designed and CNC machined drive hub
*A new Honda square shaped o-ring to seal against the case
*3 new Honda chrome plated attachment fasteners
*4 new Kawasaki cushions for the drive hub
*A new o-ring to seal between the alternator and adapter plate
*A new 3 wire harness/connector to directly attach to the CBX main harness so wiring modification is not necessary. Includes dedicated ground circuit.

Contact me if interested,

This varies a lot, depending on what alternator is being used.
Why do you consider this critical?

Because I see on the pictures that some of them stick out more then the others and I would like it to stick out as less as possible

I think Tim's had a design that was supposed to fit turbo applications, where the exhaust pipe would interfere with the alternator and this was sticking out less.
I also remember someone selling a redesigned adapter plate which mounted the alternator more inward. Have to try to find it.

Apparently the cheap supply of Denso alternators is drying up.
