Ok I re-designed the starter arrangement.
This time I am using a Royal Enfield sprag. I machined a sprocket to take two 12mm x 28mm x 8mm bearings on the inside and a 35mm x 40mm x 12.5mm needle roller inner ring. This is pressed and Loctite (648) on. I machined an outer race for the sprag from "gauge plate" which will be oil hardened, this is held on a carrier keyed to the central shaft. A bearing housing completes the ensemble.

The nuts and bolts holding the reinforcing ring on the clutch are about 1.5mm from the sprag outer. I will replace these with rivets for more clearance

Hi Andy

You might find that you don't actually need the reinforcing ring! Some moto cross engines don't have them and work fine and probably getting a harder life.

Lovely, they do excellent work...
Looks like you have plenty of room above the carb top for adjustments.

The whole job looks great Andy, if you stir up that iron thing it will make a good bit more heat , considered an oil cooler?
My iron sporster got the oil too hot to touch in 6 miles.
Great persistence on the leccy leg, it will be a boon when sorted.

Remember the home plating stuff , forget my method, get a kit would be my advice, results in the real world 2 out of 10.

I bought a little 2KW muffle furnace, this had been used for enamelling and the only control was a " stove hob type" power regulator.
I built a little control panel with a K type thermocouple controller and SSR regulator to give reasonably precise temperature control.
Today I put my sprag clutch outer housing in it and warmed it up to 500 Deg C to pre-heat soak, then increased the temperature to 800 Deg C. After allowing 1/2 Hour at this temperature I dunked the housing in ex Aprilia engine oil. I then allowed the furnace to cool to 250 Deg C and after cleaning the oil off I put the housing back in the furnace for an hour to temper.
Tomorrow may be the big try out of Mk 3 starter

The carburation needs sorting out yet, it is as rich as Bill Gates. Next weekend I have entered the British records event at Elvington with both my Greeves and B31, ideal place to sort the carburation with a 2 mile long runway. I hope I can get timing tickets for both bikes at 100+MPH

I had a quick twiddle with the pilot air screw, set it to 3 turns out instead of 1 1/2.
That made it slightly lean at idle as evident by the occasional spit back but then as I open the throttle it goes back to rich. As I have not tried it under load yet, I have only run it on the full diameter of the needle.
I deduce from that the pilot jet is probably close and the needle jet is rich. I will put in a leaner needle jet and try again.
After work I made up a cable and fitted the handlebar lever choke instead of the button on the left (hard to reach) side of the carb. Its so easy to make cables with a birdcage tool and solder pot

MOT is done.
I rode down to the MOT test station, the engine feels lovely and smooth, the exhaust note is glorious deep yet staccato sound. I have a slight issue with the gearbox, when down shifting sometimes the lever sticks, I need to hook my toe under it to nudge it back to the central position

Wonderful! All it needs now is a little dirt and lots of dead bugs all over the front of it. Interesting clamps on the control levers.....

Cheers, Wilf

Over the weekend I entered the records meeting at Elvington. The B31 behaved beautifully, fastest one way standing start mile 85MPH.
The bike is very smooth, it would be comfortable at 70MPH all day. I have a very slight oil drip from the clutch case but that's all.
Wilf, the levers are replica Tomaselli matador alloy levers. I modified the brake lever to a compensated twin pull

Those lever clamps look so much better than almost anything else....especially the ones that are so thin that the whole thing can't help but flex when used. I must keep an eye out for something like that.

Cheers, Wilf
