My newly aquired 650 clutch has only 4 friction plates and apparently not enough room for 5 , so I suspect that they are dommy plates , I think 650 plates are thinner , has anyone bought the correct plates lately and from where?.

650 clutch
As i have plenty of issues to fix i will probably just fettle the 4 plate 88/99 clutch and use for testing and running in till i find a good deal on some 650 friction plates . Alternatively i may modify the basket and plates to the Kegler design which gives a light slipper / self servo action and will not slip under 650 power. The best of both worlds, if it works.

Yes Bob - I do remember the Kegler designed servo clutch centre but I cannot say that I remember anyone in UK making or selling them. Nowadays machining the spirals on to the casting or bar should be easy. I do remember talking to MH about it some years ago but if he did make any I would be surprised as he usually offered his improvements through his spares business. I wonder if Bob Newby or Tony Hayward ever made any for their clutch and belt drive kits ? I would be interested in buying one if you're getting a batch made . My left forearm is like POPEYE's and it could do with a rest. One finger operation would be a blessing. Cheers, Howard

AMC 650SS Clutch
Hi Robert
While the Dominator Service Notes were temporary "stalled" (40 years in the making) a few of us set to work on the Dominator Technical Directory. NOC website > Technical > Heavy Twins. Page 9 onwards you will find part numbers and as many cross references as I could find. Most economical way is to buy a complete assembly (guess who spent hours / years trying to match s/hand parts with new, then bought all new. V expensive!)
Les Emery machined a thinner Pressure Plate, for me. There is a part no so he may have put some into stock. It stops the P Plate destroying the primary cover.

Hi Tim, it appears I have everything except the right friction plates. The kegler modification I would like to make is the simpler version that can be done in a home workshop . If successful I will post my experience.

Seems like what i have can be made to work, After some internal fetling with files and emery , Shortening the clutch outer cable and resetting the box lever to its furthest position, finding the best cable run ,setting up the pressure plate with a dial gauge I now have a one finger light clutch that frees off perfectly and grips well. A set of 1" bar risers will make it perfect.

Yes Bob - You're correct - 4mm as against 5mm. So five plain (pockmarked) 5 friction (also pockmarked) and the final plate also pockmarked with only one side having friction material. I understand that all the main dealers sell them by request. Cheers, howard
