I think I encountered this problem when I fitted a set of rear suspension units that were longer than standard (in the days when cost mattered, they were cheap!).

I think what you describe is what I have done sucessfully in earlier years. The only thing I would suggest is to use a friction plate with a good amount of friction material remaining, and with the inserts still firmly located. Too thin a plate could risk it only partially locating on the clutch cen...

No nuts normally, as they would get in the way of the rear chain. The screws can be tight if a little corrosion has taken place, I have also removed them using an impact driver. although there is not a lot of room to swing a hammer to give a firm blow , also use an impact driver bit with a good tigh...

There were two depths of compression rings for a VH, the low(er) compression pistons have depths of 0.115" and the higher compression pistons have a depth of 0.130", the other dimensions are the same (1/16" thickness and nominal oversize). I think your piston may be a 7.5:1 compressio...

I have a HSmk3 profile cam that has been built up on the base of a twin lobe cam, that has been ground down enough to allow the single lobe profile to be built up and ground to shape. Not sure if it was a F cam or a 642 cam, the latter has more meat on it to allow for reprofiling.

It is also possible that the dynamo has jammed, I once had a dynamo converted to 12v that overheated the armature and unsoldered the commutator segments, jamming the dynamo rotation. As a result of this, the slipping clutch assembly in the magneto slipped (!!) and generated a lot of heat in the magn...

There is one on EBay at the moment, item number 283633221042. I have brought from this seller before without any problems, but that was for dynamo parts, so ask seller if you need further info.

The size and angle of the larger end looks like it would be used to tighten the nuts retaining the head steady to the underside of the cylinder head on a Huntmaster. There is not much clearance in this area, and I have in the past had to use a shortened cranked spanner to tighten these nuts, as ther...

I am not familiar with the setup with a MN1E magneto, but recently on a K2F magneto I had obtained I found a screw retaining the leaf spring was not screwed fully home, and was making contact with the cam ring, and interrupting the points circuit. Shortening the screw and making sure it was fully ho...

If tightening the adjuster nut once the primary chain is at the correct tension, always tighten it so that it cannot be pulled back by the rear chain, from memory this means any gap in the nut is to the back of the bike. Otherwise, the higher pull of the rear chain will overtighten the primary chain...
