Question: Classic 650 class, rule number 5 as stated above, "5. Unit-construction BSA A65, up to 650cc, in Clubman trim." As unit-construction BSA A65 are 654cc as stock, do they expect you to sleeve them down? Not an issue, unless you win and get protested, but ????

Well, yes. it's 4cc over 650. When the rules allow an overbore of what, 20, 30cc? I guess it's called embracing the spirit of the rules. Besides, I've yet to see a BSA outrun a Triumph. Anyone out there besides Semper G willing to try?

Mike, it’s kind a funny that BSA vs Triumph and speed is still discussed. I Guess that BSA who owned Triumph had a good laugh as it just increased the interest of their two brands

I accept the challenge. Bring your Trumpet to Bonneville next year and we'll see about that! (Although I may be a bit disadvantaged; after all, I only have a 597cc single cylinder BSA.)

Alternately, I could build an A65 track bike that would run circles around your Trumpet, just as soon as I can get Dave Roper to ride it!

The triumphs were more expensive to buy I believe, it wouldn’t have been good marketing to have BSA’s A65 which was better for its bore:stroke and combustion chamber profile to beat a triumph.

Had BSA used the same bearing and end feed on the A65 from the word go, you’d probably be finding there’s more competition on the track.


Now let’s all have a beer beerchug

Admittedly it's a bit like rolling a rock up hill but some of us are still rolling. PRT

mike, do you have any photographs of your machine?

or of anything conforming to "GP or Clubman racers in essentially factory-standard trim?"

the rules don't say anything else and i've never seen one to know what we're talking about.

searching on "clubman trim" just shows me stuff like this:

Hi Kevin.
In the UK there used to be a Clubman class. Until the Goldstar dominated it, the idea was that the bikes were road bikes that could have been legally ridden on public highways with parts that came as stock from the factory , hence the Clubmans Goldie that came from the factory with clip ons and rear sets if desired. No factory one off specials allowed.Perhaps this is the spirit of your US Clubman class?

It is indeed what they are after.
I'll text a photo to you later. Much quicker for me that posting here.
I removed the clip on bars recently and replaced with a superbike bend. Experiment to see if I could get some more leverage on the front end. Reduce the work load as it were.
