Britbike forum Forums British Motorcycle specific Brands Bsa bulletin board My Beezer is a...Hybrid-! (the Shame-!)

I have always messed around with Triumphs and still have a couple of 'em ('72 T100R, '71 T110).

This '67 A65 came into my life and I have really become an enthusiast. My bike is very pretty but not "correct" by a long shot. To start with, it was born a '67 Lightning but now has a '72 one-carb engine, so it looks like a T-bolt, with appropriate side covers & decals. Fine with me. I think the valve cover is different as well.

I wonder: is this old Monobloc appropriate for a '67-? (I just read that the Concentric was introduced in '66.) As it is, fitting the air cleaner is a real hassle and I wonder if a Concentric would remedy this. Aesthetically, the MonoBrick looks cool to me and barely leaks-!

Sorry for the dumb questions--this old machine fools a lot of Beeer people until they look more closely at the clutch cable, etc.

As far as I know, the only 67 twin from BSA that had a Concentric was the Spitfire. All other versions fo the A series had monoblocks. So go for it. Besides, it's your bike.

My '67 A50 Originally came with a Monobloc.

From what I've heard and seen, the monos are a more robust carb, mainly because of better materials on the slides. They are much more expensive than the Concentrics, though. I'd stick with the mono.

Buzz,

I have two '67 A65L's and both came with Monoblocs.

On your valve covers: I have three different types and each type will only fit the head that they were designed for. My '71 A65L has an earlier head on it and I have to use the early non-finned valve cover on it. I kind of like the look so haven't tried to change it.

Hope that helps
