B44 Victor frame drawing

[koncretekid]

I'm building another Victor using leftover parts including a 1970 B25 frame which has the muffler mount on the wrong side for the B44 motor. I can cut that bracket off and move to the right side, but exactly where is it located dimensionally? Is it exactly the same position as the B25, or is it higher up on the frame for the taller motor?

It's actually lower down....on the B44.

The B25 one is on the left, 220mm from the top of the welded footrest mounting plate to the centre of the top hole in the exhaust mounting bracket

The B44 on is on the right, 170mm from the top of the welded footrest mounting plate to the centre of the top hole in the exhaust mounting bracket

I would suggest a dry build and put it where it needs to be, and the Victor silencers and brackets differed from year to year.

The bikes I have just measured are both 1969

Thanks, although the "dry build" in this case would have to wait quite a while because I need a proper exhaust pipe (nearly impossible to find the correct one) as well as a muffler. So I went ahead and sand blasted and painted the frame because I was bored, and impatient -- it's only paint and I can fix that later. I'm also considering just adding a single lug like the early '66-'67 models as I always liked the peanut muffler best.

I preferred the peanut muffler too, so used one on my '69 build, but had to make up a mounting bracket to fit the '69 frame

have fun, looking good so far

What year exhaust pipe are you looking for? I wasn't aware ther is any shortage of VS pipes... though one needs to be smarter than the "one pipe fits all" ebay vendors.

one needs to be smarter than the "one pipe fits all" ebay vendors.

Yeah, you see "fits all B25/B44/B50"

Actually that's a mixture of different bore, stroke and exhaust port diameter. So probably fits none...

had this made by Ben at Raysons exhausts for my b25 special, he makes front pipes and silencers

Thanks for the replies. As for the correct exhaust, I bought a new one from a reputable vendor that didn't fit my Colorado B44, so I bought a used one from BSA Unit Singles - - that fit. I've bought another one on ebay, but that didn't fit either. I have a nice new one that might be B25 high right side, not plated, so I may be able to modify it to fit. As for the lug on the frame, I'll just have to deal with that when the time comes.

The factory exhaust pipes had the year and model "sort of" stamped at the arse end, usually something like B44 69. Generally hidden by the muffler and carbon/mung build up... don't know if any aftermarket pipes had these stamps. This has proven a big help identifying very similar looking exhausts over the years.
