Heavy Twins

I write as an amateur.

I have two Dominator99s  - one I rode as a medical student 50 years and is currently restored (ish) and roadworthy.

My Atlas is running on BN8ES plugs. I don't think it likes them. Misfires intermittently until the engine is hot and then when I give it some welly the misfire eventually clears and she runs great, and when I say great I mean it.

Currently playing with twin concentrics with a cable spliter and adjusters on the carb tops. Unable to get near slides as box filter in way . Can set tickover and mixture by ear or Colourtune no prob . but do not want to disturb filter box .

In order to protect the tank in the damp space that’s my garage I have been closing off the cap breather hole by sliding a tiny fridge magnet over it .The magnet lives on the cap and is almost invisible.

My 1966 Atlas which had sat for FIFTY years untouched has NO oil in the forks, evidenced by the fact that with the oil drain screw removed nothing comes out.

I have an ex road race bike that I am converting to road use. It is a Featherbed with a Commando engine fitted upright. The gearbox is a five speed Quaife with a race first gear and no kick start.

Can anyone tell me how to index the Cam plate and the Quadrant on the Laydown gearbox? Thanks

I recently acquired a 1966 Norton Atlas that apparantly had sat forlornly in the back of a garage since 1972. Yes, that's 50 years untouched!

What a super resource this is,  Free and easy to use. There will be usefull information in there no matter how much you think you know.  Thank you to all who made it possible.

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
