if the carb to head rubbers are drawing air and causing the revs to hang when you shut off, you can check by spraying a but of easy start around the rubbers when the engine's idling. If the revs rise as you spray 1 rubber, its leaking

+ box section swingarm.

I know you can get kits of thicker engine mount plates - that would stiffen things up , and would be easy to add at the stage you are at now.

if you used a little dialectic grease there( ie electricity- conducting) after doing your yearly scrape then that might slow up the oxide reforming between the crankcase and the ring terminal

braced frame was a worthwhile period mod, especially if you're going to try and add power but looks like it's too late for that now. sorry to piss in your chips.

your bike's lovely , keep an eye on the posts for meetings etc.

sounds like a great and worthwhile day out, and nice one Fer and Kath.
It would be nice to have a couple of Zed meets next year to put faces to the names

It bolts directly to the tank top surface - I've included a photo as it was originally

Racing- type twin quick filler , came attached to the hand built tank I got with the project I'm working on. I've converted the tank to a more conventional opening. The tank was made originally by the Tank Shop in Dumfries , I have spoken to John there and he remembers the tank and has pointed out t...

we await with interest your application of logic and stepwise exclusion of possibilities - it's what we all try to do.

to clarify - resistances and continuities in each coil, and compare the readings between the 2 coils

I tried the Wired george mod to give the coils full voltage and it melted them., 1 after the other. If you have a multimeter compare the resistances and continuities between the 2 coils - you should be able to do this without removing them. 1 of the coils might be on the way out, and reversing the m...

2 inner cylinders - I'm thinking the coil that feeds those 2 cylinders as a starting point to look at. Are you on electronic or points ignition? If points, then the points ( gap, points surface and timing) or the condenser that feeds those 2 cylinders might be the next thing to check

top news, and compression might get even better after its run a bit

put it in a pan of warm water, and bit by bit add boiling water ( not directly on the glass so you don't crack the glass) after a whole kettleful give it 5 mins then take it out ( use pliers) and the metal should have expanded a little
