Speaking of very old BSA 250s..........

Postby Tman » Thu Nov 12, 2009 10:16 pm

here's my latest project, a 1925 BSA Roundtank 2.49 HP side valve (or B25 to give it it's correct moniker)-

Actually, Googling for parts for this lead me (via Dig's BSA) to this forum.

Been sat under a hedge (literally) for God knows how many years, the tank shows daylight at the bottom and the bottom engine lugs are pitted badly. The engine is still on a STD piston, and looking at the various nuts, it's never been apart until now. The forks didn't come with it, nor did the second engine and carb, but when you start buying parts they tend to come complete with other parts. Not a problem, as they're always good for swaps.

Still need hubs, manual oil pump, magneto and rear frame section should anyone have them. There was a lot of commonality with parts in this range, but I'm more interested in getting a running bike than absolute originality.

MOUSE"]:39 look forward to seeing the end result.
Something like this http://motorbike-search-engine.co.uk/cl ... d-tank.jpg


Something like that originally, but I'm hoping to use a dinky little front drum brake (the 1926s did anyway) rather than the little rear drum + the dummy rim brake also on the back wheel.
The little front drum will give better braking and look better, and the linkage for the rim brake is quite complex (read- "rare") apparently.
*If* I could get the missing bits, I reckon I could have it running by next spring and road-worthy for the summer runs-out, but it's just the luck of the draw as to what turns up.
Think I'll join GBC's Old Codgers (VMCC) Club and see what their members mag has for sale. Can't see too many 90 year olds touting their junk on Ebay....

Valid point, there must be a host of sheds full of usable spares, but owners won't have a bar of new fangled p.c tech (although it's been around for 30 years)

Hope you can source the bits, looks like a project you will get a lot of pleasure from.
