Heavy Twins

Could someone tell me the size of thread on the drive side end of the crankshaft please?  Specifically on an alternator model.

Thanks in advance,

John

For a year or two I have been fiddling with  carb on my 99. The bike starts and ticks over very well. It gets along better than most too. But it has had an annoying  "POP"   several times during a run out and can stall  at  awkward moments.

 AMC  altered the geometry by lengthening the valves and shortening the pushrods on the 750 motors.  They did not make any recommendations about the earlier 500,600,and 650 twins.

Hi there, 

I've a problem, my primary chaincase is off at the moment, it has no clutch adjustment açess hole in it as found on later models, so before refitting it, do I;

1. Leave it as is with no access to the clutch adjustment.

Hi fellow strugglers , I have been dealing with Armour motorcycles of Bournemouth and am not best pleased with the results . I have a timing side pipe that I think is useable but I am on my second drive side pipe and neither fit at all well.

I have been asked a question by a member who is putting together some words to go with his bike when he displays it at a steam rally at the weekend.

in 1960, how much would you have to pay for a dominator 600 delux. Slimline frame.

For some years I have been trying to source a pair of footrest rubbers for a slimline dommy . Our suppliers think they have them , but up to now they only have lightweight ones (which don’t fit) , no one seems to make them now (no demand!!).

This is my Wideline frame, The front engine plate brackets denote this as a frame for a twin. What's left of the frame numbers looks like it's a 'P' - 1959.

Hi, I need to put oil in my AMC gearbox, my Haynes manual says Hypoy but no grade - I presume its 80 or 90. But Mr Google tells me it is SAE 40 or 50. Our technical section only describes oil for the lightweights.

I refitted the rear wheel on my Atlas in the correct way with the spacer between the swinging arm and the speedo gearbox but when I tighten the right side wheel spindle nut it crimps the speedo gearbox and the wheel ends up being tight also.
