thanks for the info chaps. all usefull stuff. nice bike John M. I am literally about to start my build this week, so the timing is perfect! (excuse pun) thanks

A gearbox in that condition should be no problem to put right [wish I could put some of my pics on here, but that is harder than fixing anything]. Regards, Paul.

@Bullet Whisperer

Thanks for your reply. what tuning you recommend for bullet 350 trials bike . have you tested Asbo bullets on offroad/trials etc or it is different kettle of fish

Hi enfield_trials,
The bike that started the whole 'Asbo' thing, in name at least [there was one before it, retrospectively named 'Father of Asbo'] was an off road style Indian 500. I did it for a bit of fun, it was my own bike, but i let a friend who used to ride enduros have a go and he reckoned it was good enough to compete on and pestered me to sell it to him for an AJS 350 and too much money for me to refuse! It would lift the front wheel in 1st and 2nd gears on 17/38t gearing and had a top speed of about 90mph. Pete [the owner] has done a couple of dragon rallies on it and all sorts of off road stuff and is very happy with it, although, with lights etc, it is no trials bike and Pete reckons it is really more 'enduro'. Regards, Paul.

Thanks very interesting..good to know the bit of background of Asbo .. you were using standard bullet frame on your initial builds .. ?

Yes, just a battered old Indian 500, with an early looking 'trials kit'.

al do theoreticly true that you can fit a MO1 or N1, mechanically fitting these on a points bullet is not as easy as it may look.



yes, the provision of the straps it there, but that’s about all



the flatend area a top of the casings is missing on the later points bullets.

and the area where the magneto enters the casing is to thick on the points bullets.



hence you’ll have to adapt this to mount the magneto ore magdyno straight and true.

and even then you’ll still have the fix the problem of the magneto axel being to short to mount a fixed pinion or even the same auto advance as on the SR1.

so it sits in line with the other idler pinions.



the easiest to mount on a points bullet is an SR1, its a straight fit.



anything else is a lot of work to get to fit(straight and true, no oil leaking) and working correctly.

Hopefully I will have been more successful with my images..............
I've just noticed from your pics that you have a 1955-ish 350 Bullet, so a Lucas SR1 won't fit without modification as the SR1 is wider where it enters the timing chest and it won't bolt up with the three bolts found on the 1956 onward bikes, as the earlier bikes don't have room for the bolt holes.............. Have a look on Hitchcocks used crankcases and you should see the differences.
Mine has the same design of timing chest as yours, but it has been opened up to take the SR1 and it relies on a modified magneto strap and mounting platform.


In answer to your earlier question regarding the SR1, it is a magneto only, they have no facility for a dynamo, if you wanted lights you would need a magdynamo, I manage without.

Hopefully there will also be some images of the rear engine mount that I fabricated to follow the Bullet designs, or a few empty icons to add to my embarrasment!

It depends what it's like inside but as long as there was oil in it when it was stored, probably, yes.

REgards, Mark

The SR1 magneto is just that, there is no dynamo. The Lucas magdyno used on older Redditch-built road-going Bullets is a magneto with the body casting designed so that the dynamo sits on top of it.



You'll note from the picture that the SR1 is fitted to an older (pre-56) set of crankcases, which is why it's held down with a strap. I should have clarified that it's with 1956 and later engines you can bolt the SR1 directly to the crankcase, at the back of the timing chest. Also from 1956 crankshaft-fitted alternators replaced dynamos.
