Thanks Phil, it’s great apart from things like poor brakes (think no brakes!), there is no tickover facility, evidently the idea was you stopped the engine by closing the throttle!, I’ve set the throttle cable to hold a tickover but have to stop the engine by stalling it on the clutch now, also trying to remember that the gears and rear brake are swapped over is a nightmare, it’s ok until you’re in a panic situation and then you’re pressing the gear lever instead of the brake, the only thing to do is ride like an 80 year old granny , that gives you time to put right what you’ve just done wrong:), charming little bike really though.

Ah yes forgot to say, I’ve put it on the 12v charger several times, checking it with the multimeter so as not to overcharge, and finally today it’s holding 6+ volts so a success, thanks.

Yes thanks for the advice Moorey, I was about to buy one until you suggested using my 12v charger.

I know modern bikes are very efficient etc but when it comes to maintenance this thing is ridiculously easy, remove primary drive cover, 1 nut, remove flywheel cover 3 spring clips, I changed the crank seals in less than an hour earlier today, what a simple bike it is to work on, anyway handover to Father tomorrow so he can continue to improve it, I guess the caveat is that you had to maintain these machines more often than modern bikes but wow it’s easy!.

Nice bike Mark, I remember them well from the 60's. Other nice bikes to with 2T and 4T engines. They are real classics.

Thanks Masonmart, yes it’s a nice thing considering it was made as a workman’s commuter back in the 50’s, well the handover to Father didn’t happen!, it ran beautifully on Saturday evening but on Sunday morning it resolutely refused to start, no idea why but the spark was weak, the night before it was very good, so I’m picking up an electrex electronic ignition kit for it on Friday, I had planned to fit one eventually but will do it straight away, also having it rebored, I’ve picked up a NOS oversize piston so I’ll get that done as well, I’ll be good for a few thousand miles then.

Cor.those Villiers motors are tough.
Hope it finally gets sorted and the handover goes well

The problem I've had with classic 2T's of mine (super 6) is that eventually you can't get them to run well because the crankcase seals harden and fail through not being used. Small 2Ts were amazing then because there were so many different variations. They're difficult to use now because of the performance gap with modern traffic. Still fantastic bikes.

I had this T250 up until a couple of years ago, no problem keeping up with traffic on that as you know with your super six they go like stink!, no wonder so many 17 year olds came to grief on them back in the day, as you say the older 2 strokes are a different story, 60 mph flat out for the James and about a week to get there, worse than that though are the brakes, bloody terrifying by modern standards!

I seem to remember that the condensers used to fail for a passtime and that could be your weak spark.

Was that basically an off road Hustler?
One day I'll have the time to restore it, not just talk and dream....

Yes, in fact I think mine was a Hustler, I fitted the high pipes which I got for a bargain £70, it had chrome road pipes when I bought it, pretty much the only difference though.

The condenser is being consigned to history tomorrow Bryan, and the points, and the brass flywheel, I went to Villiers spares in Brierley Hill today and bought an electrex electronic ignition kit, (had a “while you wait” rebore done as well), should achieve CB750 level reliability tomorrow, well almost 🙂
