It may be that the fuel vent is clogged... try removing fuel cap and see if problem goes away.

I've tried that but no difference I'm wondering if it's the ignition switch as when it cuts out you can't start it again unless you turn ignition switch off and then straight back on it will run If it was the cap not venting it would build up pressure in the tank and I would here it when releasing the cap ? It's so random If some part was heating up ie the A/B boxes surly just by turning the ignition off and then straight back on that should eliminate them as they would need time to cool down I'm trying to locate a new ignition switch in the uk but not having much luck

If it was the cap not venting it would build up pressure in the tank and I would here it when releasing the cap ? No... it would not be noticeable. It was just a suggestion. If it were a partial blockage rather than complete it would only slow fuel to the carb and still enable restart.... foolish me!

Actually the fuel cap I have is an after market one and just looking at it and comparing it with an original one it should have a vent hole in the centre inside and outside this one dosent So can I drill from outside all the way through not quite sure of the size hole but fairly small

I had a similar problem on my 71 H1. Turned out to be a bad connection in the main white wire connection coming from the switch. Bike would just die , roll to a stop and would start up again and go. With the tank off and key on play with each wire coming from the switch and listen for the ignition buzz or, lack thereof.
Again, just a suggestion....

Thanks for the reply I have checked through all of the wiring found a few which were suspect and replaced checked either end of wires to make sure there is no breaks in each wire it's so frustrating im still wondering about ignition switch as it does look like it's had some kind of glue or resin where the wires are soldered maybe there was a cracked on the contact bit?

Regarding the ignition switch:
This can be opened to clean the contacts: Bend back the thin steel case retaining points and the phenolic back will come free.
Clean all parts with contact cleaner.
Rub all contacts with fine 600 grit.
I did mine many years ago and assembled the unit dry after final cleaning all parts with contact cleaner.
How is your charging system? The early H1's are bad for breaking the windings of the alternator rotor. This is hard to find because at rest they test OK.
Be sure you have 13+ volts at battery with engine running above 2k rpms.

Still not found my ignition problems as yet but I haven't took the ignition switch off yet but on another note I thought I would tackle a weeping clutch cover now when I looked at the the distributor rotor it didn't line up with the pointer on the casing so I e realign that now question here should there be play on the rotor when on the shaft movement being up and down by a few mm

Are just looked on the resources page and read about the rotor service bulletin and the black rotor which I have should have a screw to hold it in place which mine is missing wonder if this could be any thing to do with the engine randomly cutting out?

My black rotors do not have a screw.

If you take the rotor of the shaft there is a threaded hole which lines up with the hole in the black rotor I can't post photos on here but will post on the face book page but this still hasn't solved the cutting out ive manged to get another ignition switch which will be here in a couple of days

Here in Canada the 69s had a brown rotor. In late 70 or early 71 they switched to a green rotor which was replaced by a black one. The brown one had a brass contact that was exposed all the way along the top.
