Aspects of a 1969 BSA built to work, every week.

[ratheads]

Yikes, the seat and catch bottle are lovely !

[441rider]

I think the word is challenged! but the airtube in that seat is comfy.

[waspfarmer]

This vid needs something. Perhaps a fire or an explosion of some sort. Perhaps seeing the bike use it's wheels somehow. Even a narration where the builder explains the use of bronze bulleted valve guides with necked valves, or why it's yellow. Something!

[turn4don]

Cool classic!

film qualty mostly clear, Biker uses stick-UMS, lickable red rear cat.

running speed regular, can pick up a rattle noise on the BSA 350. One of the better rolling films

[minorinminorin]

Good sound of Engine!

Great bike and obviously well used and loved.

[sthawkonthetube]

Cool, I used to have one of those. A B44R Shooting Star. Red and whoite model. Mine came to me when a neighbor's son (6) found the tool box in the garage and started finding all the places the wrenches fit. You would be amazed at the things a 6 yo can do with a wrench! The neighbor was afraid he'd try to start it...

very nice bike

[441rider]

Thanks, guess the 18 years of looking and riding it has payed off. I dread they day a lever get messed as in 15 I have never seen another pair of Tomaselli short racers. I really should get them cast some how simply the most comfy ever. The 1/4 throttle made me really get serious about tuning and I make a 73 degree side draft I run now for more revs.

You could probably do well on ebay with the Tomaselli levers. Honest copies of rare items sell well, and if you get 'em cast in good metal word'll spread.

golden oldie dbd 34 veteran-norton,velocette and ajs were undistutably the best singles on the planet!

[eddietwang]

terry,you forget,panther,early triumphs and bongresoid.l believe bongresoid were the first company to use claptic valves on there o.h.v engines...stick that in your pipe you big puff.

[441rider]

Hey hey, there are vintage 250's I know that will top 125mph so size does not always make a real motorcycle a bike YOU can fix with no help is a real bike. 500 is comforting on the highway though LOL!

[eddietwang]

l had a 1967 250 royal enfield crusader sport which was converted to run on light particles,via a timeloop transducer.on its first kick it backfired creating a "time portal",which sucked my mechanic into a nightmare world populated by flesh eating cavemen...l havent the guts to try and start it again

[bsab26bobbed]

LSD!

[eddietwang]

no,hash cakes!

i am thinking about making my trailblazer into a cafe racer. it would need a b50 motor first. that would make it into a real motorcycle.

my uncle has a b50 motor just laying around that he wants to modify, and put in his triumph tr25w, but i will try to beg it off him. how do i keep the oil in frame from getting plugged. i just check the oil return feed pipe periodically to make sure its pumping.

[441rider]

Just remove the bottom plug and be sure to wash the brass screen if there. You can blow out the screen w/air as well. Have not had my MX b50 for ten years so check a workshop manual too. I may have just had build up of sludge but checking your return is a good habit.Steve

i have a 1971 triumph trail blazer 250, and it is completely stock. i love the sound of the singles. is that a victor?

[441rider]

Yes, it started as one at least. You can put a 500cc b50 motor in your 250, just don't burn out the parts to fast and make sure your oil frame system never gets plugged.

[roadrocket]

what is the rev ceiling on those?

[441rider]

safe max with true tight stock engine but worked in say 4000-4500?

[roadrocket]

I feel it should be higher than that. One time i had a race tuned zb32 which would safely rev to 7000 without any ill effects.

[441rider]

I am pretty sure the Rupp snowmobile tach is accurate but heck I did adjust it once. Must calibrate but the GS engines can spin faster than the 441 B50's I think, the 441 is square almost bore/stroke wise so that may hamper it. I will have to get a proper calibration, the 250's would rev and blow up at 8000+ but had different configuration stroke wise.

[amdidextrous]

You are correct, roadrocket, my race tuned DB32 used to manage 7000 also.

[roadrocket]

is that a B50? love the backlight

[441rider]

It's actually a 441cc BSA w/extensive flowing of the stock head. Many oil feed mods and a B50 clutch pack, polished and statically balanced crank by a vet mechanic. It spins to 5000-5400rpm so far, planning new head bigger carb and valves next.
