Comet Gearbox

Goggle TT industries NZ, Bruce makes all types of gear boxs
Probably better to go for the Norton/ A.M.C. design anyway. This can be fitted to the Comet. I can't remember if TT does a Burman design. Page 203 of "Forty years on" refers to the fitting. I couldn't afford a new gearbox for the "Comet on Steroids" and it has a Burman gearbox. Wish me luck!
TT Industries do a Burman but its a AJS 7R type they also do a Burman BAR actually quoted in their advert "For Vincent Grey Flash" Imagining the cost and the fact that the 1950's IOM team threw them out for Albions I kept the faith for my Grey Flash replica and fitted an Albion (the jury is still out) . In any case Gearbox choice for the Comet becomes a lot easier if you use a belt drive its fixed centers make fitting any box a lot easier since you dont have to allow for adjustment slots and swing (A fact not often mentioned)
I put the Albion in my G/F Look alike as well, got me from a to b no problem, I was lucky, started with a N.O.S. It took a bit of doing to fit it.

Russell,
I would not recommend it for a street bike. I have used the BAR for years and it is an incredible gearbox, but it is a true racing box made from magnesium and no kick starter. It is quite a bit of work to fit with making all new plates spacers and modifying the F106. Finally, it is expensive. I thought that it was well worth the price because it gave so much reliability and the shifting is flawless. However, I had to travel thousands of miles to attend Bonneville and Miller as well as other racing venues. The cost of failure was too high to be cheap. Ken Genecco on the Ex-Dickerson Flash went to Miller 6 times and raced in only one complete event with the Albion box. The Albion is a good box, but the gears are not made of EN36 and it sheds teeth at a high rate.
Bruce makes a Norton box with a kick starter and it can be had in 4, 5 or 6 speeds if that is important. I would look for a used Norton box with a kick start. It is inexpensive, robust and relatively easy to fit, mostly because so many owners have done so.

Tim,
I think you are quite right. I have had great success with the Albion also. It is a passive/aggressive gearbox. The belt drive primary is the best!

Hello Chankly, If it makes you feel better, The Alexanders raced an 1150 twin in the 80s, With a Burman box, And it did very well, He was always too fast for me !! Cheers Bill.
