If your issue is jumping out, Coljen gears in Heidelberg will undercut them.

Good recovery Zane. The old PayPal cuts both ways but is probably the reason eBay still exists- and vacs regardless, so many old bikes are viable restorers.

The new rules are to go via the Board of MA so until then Im not going to comment specifically on the new rules but I will comment on the B44.
Some years ago the commission created pre 68 unit and pre unit classes with the view to see if the take up of this class would foster and grow an alternative to the pre 65 arrangements and the fact is no one supported it until we took it out of the book. I would have to go back over the corespondance but I seem to remember that I have mail saying there isnt a snow balls chance in hell we are going to run that class - we want B44s in pre 65. The pre 68 rule was taken after a look at the UK experience and the success of same; why why why would we want to revisit that when there was an earthquake of non support for the attempt to create a new class that was so clearly rejected?
The new rules (should they be passed) will not cater for the B44 or any other bike that was made after the 1964 model year unless considered a follow on - a distributor B40 is an example of a follow on, a points B40 isnt.
That the proposal will allow a frame to be essentially free is an attempt to allow riders to get an engine, find some period hubs, forks, tripples and make a bike fit the suspension criteria. It should be possible to do this cheaply and easily as the biggest hitch in building a bike was always questions over frames. We have just had Australian Champion classes at the CDT nats in pre 60 and pre 65, there is growing support for these bikes. If I was going to build a bike I would build (say) a B33 make a light copy of a Matchless frame get an AMC gearbox, some Royal Enfield forks find an alloy tank, make a seat that works and go racing. In pre 60 and pre 65!
On the B44 matter - as I have said before - while ever the B44 remains at best the 1965 model it will not compete in pre 64.
On the back of the attempts to placate the B44 riders with things like the pre 68 class -  rejected what are we to do? If the new rules get over the line it will need riders to support it, if no support I dont know what else to do.

This response from commissioner DT seems to have answered my question about points in case B40's.

The windsock is a bit limp.

I am looking at a late B40 BSA powered Pre 65 project. I know there are no issues running the early distributor type version of these engines, but has there been a resolution, or is there a consensus or precedent for using the non dissy, points-in-case version in this era? Thanks, Marcus.

1984 RM80 big wheel had a 1.40 x 19" 36 spoke aluminium rim on a drum hub- probably the only bike brought in with that combo.

Same idle issue on my RM370 John- case reeds and a replacement new VM38. Played around with the normal calibrations but it would not idle reliably. The speed screw was all the way in and graunching the spring. I ended up taking about 1.5 mm or so off from under the screw head- about 2 turns and voila. I will get around to turning up a longer screw with a decent finger grip at some stage, but in the mean time it is fine with another turn in.

I don't like letting it idle much anyway, just so it will run at the gate when something needs doing with the throttle hand. The original carb had no idle screw and there have been various theories offered for this. One of my own is that Suzuki realised their ignition system was on the weak side at low rpm/any rpm and long idling was a recipe for a plug foul.

Yes and yes. Engineers rebuild with machining and mucking around required though.

The insurance I need is medical incase something was to go wrong. The second motocross is mentioned things get either very expensive or we don't have a policy that will cover you
I contacted ridersurance in the states who specialize in finding coverage for racers but they are only able to do annual policies where I'm only there for 1 weekend of racing

Doesn't sound excessive at NZ1500 if they are covering you for ambulance rides including in the air and hospital treatment. I assume extended travel insurance would cover any medical needs for return air trip.

Insurance for what Tony? Your body or bikes?

John, same issue as yours: sparked out but hard to start in and a dodgy advance curve.
Nebo is onto it. There will be a stator on their list that works very well.

I am using the very similar Sellettra CDI that is matched for rpm and advance on a couple of high winding little Hondas and they are very good.

John, the various PVL's are not all suitable for relatively slow rpm kick starting. I was forced to investigate after a seller knowingly sold one to me for my B50/Clews that was incorrect. There are various PVL's out there selling cheap with low winding numbers that are apparently redundant homologated units made for 15000 rpm Karts .  There are also various mismatched combinations of stator and coil. PVL list about 70 different stator P/N's.

Well, you might be onto something with the lads. Have they seen Tony Bou on a trials bike?

The SL90 with the vertical cylinder is interesting. I think they were a 1969 model, at least in Japan. If any landed here it would possibly make them eligible for 250 cc Pre70 VMX.
