Here are links to the dist photos. My black rotor definitely has a hole in it for a fastener to go through the hole in the shaft. The inside of the rotor almost looks empty compared to photos of others I have seen. I cant tell if this set up will work. It came to me off and in a box, while the clutch cover was bolted up . Makes me think that it did run and he didnt destroy the rotor to remove it?

Sometimes, way back when, dealer and other techs would break the black rotors off, butcher the screw out of the hole without taking the clutch cover off, then just put another black rotor on, no screw. That left the.new rotor loose on the shaft, as the FDM updated rotor had a steel tightening devise in them that the black rotors never had.

Black was held tight by the screw, FDM by the spring steel tensioner insert.

Yes, when my rotor is just slid on the shaft, there is loose side to side play. Sloppy fit. Wonder if I can tap a roll pin into the hole to snug it up

I'd suggest looking at car rotors at the auto parts store, some of them use the spring steel tensioner pieces I alluded to above, one might interchange, and would be what to do, not the roll pin.

Be creative.

That would indicate you want to look for the FDM revised rotor, brown/red, QD, 28mm shaft, not the green rotor.

To use another BLACK rotor would require taking the clutch cover off the engine, removing the distributor shaft, and installing rotor, with hold on screw, not QD. Removing the shaft is the only way a screw can ge inserted into the rotor and shaft, if not, the screw hits the clutch cover. You can get ;em out, but not back in without pulliung the clutch cover.

If you are attempting to match the original cover paint, closest I found was a Lubri-Tec paint, and clear, "Honda Cloud Silver", and their enamel clar coat. Yes, I now, "silver", but, it comes out the correct gray/silver finish.


I am seeing a fair amount of the brown ones for sale, but I do not see the spring/retainer on the inside. Does it just slide onto the shaft with a tighter fit than my original black one? Here is one http://www.ebay.com/itm/21142-003-NOS-K ... 0z&vxp=mtr

On the shaft side of the rotor, there is the locating flat, and opposite of it, a recess with black spring steel tensioner piece. It is hard to see, but the spring steel piece sets the tension.

The black rotors were kept tight on the shaft by the tightened screw.

The spring steel tensioner is an L shaped piece, round flat, with a 'leg' that fits into the recess to hold the rotor on the shaft. You might be able to fabricate something like it from very thin sheet steel.

The shafts come up on eBay...is it possible to swap out the shaft and go with the common rotor?

Yes, easily, but, why? All that is needed with the brown rotors pictured is the steel tensoiner, and many car rotors have them, just have to find a rotor that has one the right size, and install the steel tensoiner in the Kawasaki rotor. Or, make your own. This is not rocket science, all that is needed is a spring plate that tightens the brown rotor to the original shaft, has been done under warrantee for decades to the first 8,800 units, save this one.

OP, I think I'd send a message to one of the eBay sellers and ask if their rotors have the steel plate, and if so, ask if you can have a better picture of it, then, build one for yourself (don't tell them that).

Be creative.
