Re: Be careful what you wish for

That's the 8" TLS fitted to 1968 model Triumph and BSA twins. For 1969 and 1970 the cable routing was changed to a vertical (shorter) location. It's a very good brake but the longer cable makes it feel a bit spongy and also the cable can snag under the rear of the mudguard which is why they altered ...

Re: Help with forks please!

I think my special tool is not so special.
I don't use any 'special tool', just a 13/16 AF socket on a long extension down the fork stanchion to hold the damper rod whilst you unscrew the allen screw. :thumb

Re: TR5MX Avenger restoration

Just to update this thread, I sold the TR5MX a couple of years ago to a good friend of mine and it now resides in the in the Transport Museum at Jurby in the Isle of Man. I've re-posted the original pictures thanks to Photobucket playing silly buggers. As bought. https://s20.postimg.cc/lab6olexp/001...

Re: B25SS rear wheel off set

If the bike was designed with wheels that line up, it's important for them to line up. If they're designed to have the wheels out of alignment to balance the bike, it's important for them to stay that way. Come on guys, this isn't rocket science. But these bikes are left-side heavy, offsetting the ...

Re: B25SS rear wheel off set

BSA unit singles are left heavy with the 1970 models being worst due to the left muffler mounting. Did BSA supposedly try to center the weight by offsetting the rear wheel to the left? BSA built them with the rear wheel rim offset to the right. This was solely to give clearance between the chain an...

Re: B25SS rear wheel off set

I've just rebuilt mine to 42 mm (1 21/32") offset from edge of brake drum to edge of the rim (WM 3) This puts the wheel central in the swingarm and almost in line with the front wheel, which is central in the forks. There is still sufficient chain clearance with a 4.00 x 18 knobbly tyre. BSA deliber...

Re: Trophy 250

Hi Jim, non-matching numbers and a BSA engine in a Triumph frame, be careful what you spend! Personally, I would break it for parts, you may even make a small profit to subsidise a more financially viable project. Alternatively you could look for a B44 engine to put in it, leave it badged as a Trium...

Re: TR5MX restoration

The TR5MX is basically a badge-engineered BSA B50MX, when BSA went out of business the remaining parts were built up as Triumphs. As far as I know they are identical to the B50MX except the Triumph had a 21" front wheel, a full alternator with Lucas MC2 capacitor ignition and the 2 gallon Triumph-st...

Clutch lever dimension.

Can anyone tell me what is the clutch lever (blade) measurement, pivot bolt centre to cable nipple centre, on a B50? My restoration project has a mangled, aftermarket alloy lever that is beyond use. I want to fit an original chrome lever but need the measurement to find the correct one. Thanks, Andy.

Tachometer drive

Help! I need a tachometer drive for my TR5MX restoration. I specifically need the later type drive where the cable attaches with 2 screws, as fitted to oil-in-frame bikes rather than the threaded connection. I have a NOS (new old stock) earlier, threaded version to exchange or sell. Thanks, Andy.

Re: Security Bolt Holes

On the front wheel, with a single clamp, it should be diametrically opposite the valve, that way you will need less balancing weights. :thumb

Your new, shiny rim is pierced as my 21" Jones front rim. The old, rusty rim is pierced as my 18" Dunlop rear.
