Thanks for the info Kommando...Yes the plastic guards will be removed for gaiters. The Honda yokes have less offset than the BSA yokes and that should make the steering slower. My T140 has 1995 Honda 750 Interceptor forks with the same offset as the CBR...But the T140 yokes and Interceptor yokes have the same offset. I don't know if the T140 forks are parallel to the steering stem....The T140 handles nicely so I 'll see how this plays out on the A10 with the fork angle at 26 degrees

I went for 1999/2000 Yamaha R6, 43mm stanchions so no mods to take the forks and a bit more offset and wider gap so I had bigger choice of wheels plus twin Brembo's using adaptor plates. On the F4i the green paint came off the alloy which polished up nicely so it looks old school with the gaitors.

I have been doing a lot of small jobs, painted the framed, welded on a new side stand mount, fitted a pair if nice used Koni adjustable shocks, and a fuel tank snafu.....I bought a very nice A65 Lightening tank for a great price. However when pushed up against the steering neck the rear of the tank hits where the rear frame rails are welded onto the back bone tube. I going to section a few inches under the rear of the tank for clearance. sheetmetal and brazing work and it won't show when the tank is mounted....
I got Ferodo brake linings for short money and relined the shoes.....

Re-lining OEM brake shoe frames - MOST definitely a dying trade...

Glad I came across this thread. About 8 years ago I fitted a set of Kawasaki Gpz750 forks to a spare A10 frame. Yoke offset was the same as stock and by sliding the tubes up through the top yoke enough to put on a set of clip-on bars the length is pretty close as well. Mounted the swingarm in needle roller bearings and adapted a BMW front hub and disc brake to the rear and then lost momentum in the project. I have a spare DA10 motor but decided to keep it as a spare for the A10 I run now.

Last spring I ran across this website and it piqued my interest:

https://www.tribsa.co.uk/second-rebuild

I have a T140 engine, right hand shift, that I want to fit in that frame. It just seems that Triumph stuff is a lot more plentiful and hot-rodding one will be easier. Thanks for the inspiration Mr Hillbilly!

From what I have read 60' s Triumph 650 fork yokes have a slight rake to the yoke stem to decrease trail for faster steering..So there's a bit more to steering geometry than just offset.....The 95 Honda 750 Interceptor forks on my T140 have the same offset as stock and I don't believe T140 yokes have a raked stem?
The advantage of the later Honda CBR 600 forks is they are 30 inches long from the top of the tube to axle center line full extended, the same or very close to Triumph and BSA .And I like the 43mm tubes....
Paul, yes, few reline shoes...I could buy a set of Emgo lined shoes foe 22 bucks rear and 32 front...I assume they stop ok....Some might freak out over a possible asbestos danger depending on thr age of original Forodo linings...But the linings are not disturbed when riveting and at my age something else will put me down, lol...

OE shoes work better than Emgo. Personal observation.

Not so much...most parts have some weathering or crappy paint....But the parts that make it run , handle and stop will be as good as they can be..,.The engine parts go to Carl McQuillen racing engines this week. He's not a real bike guy but he knows engines and does some vintage flat track engines.He did the machine work on several Triumph engines for me on his fancy shop equipment.
This BSA will have Triumph power ,lol

To me that rolling chassis says "put a solo seat on me or make me a flat tracker"

I'll be a racer look becase of minimal equipment. I dropped off the engine Parts at the shop..The owner stared at the crankcases and said he's built a few A65 flat track engines and never line honed the timing sde bushig and no one had a problem. He mentions making jig, set up time and how often will the bike actually be ridden? At some point larger than normal intake valves were installed, the stems are galled, no ready made replacements...He will have new intakes made from high quality blanks..The valve work done on a Newan single axis machne. Reading on the balance factor, 60% should be good for this bike
I would prefer a 2 into one or Siamese exhaust. New stuff isn't silly money but Ithe tarnshed look of used pipes is prefered if t can be found

Always wanted to make a TriBSA for classic 60's racing. It would have to handle better than a dry Triumph I'd think.

The late t120 frame was very good, 69-70. Just as they got it right, they stopped making it...................
Messers Uphill, Tate etc showed that.
The small heath frame was rather heavy but very strong. It did handle well later on.

I go nuts once I install the handlebars. I immediately roll the bike out and take a "light of day" photo against my garage door.

I can't help myself, it's a ROLLING CHASSIS!
