Kick start spring B50

My new B50 kick spring is disappointingly weak with the lever arm on. I was careful to check the number of turns on it when I bought it but it seems only just about good enough to return the lever upright. Is this normal or should I expect more fierce recoil? Do I try to force another turn to preloa...

Rocker arm ball pin

The shoulder is broken on my inlet rocker arm ball pin. There is no part number for this as far as I can tell except for some Triumph parts which might or not work, some of which don't have the oil drilling. I would like to buy either a new part or a broken rocker with a good ball that I can press o...

Re: Inlet Rocker woes

Luckily I have spacers on the front and underside engine mounts, this allowed me to tilt the engine over today, just enough (with loads of cardboard on the frame tubes) to get the rocker box out. Over half of the shoulder is missing on the inlet rocker ball, and thanks Minety, I discovered neither t...

Re: Inlet Rocker woes

Hi Minety hope you are doing well. Can you buy the ball joints separate? I've seen a few NOS rockers that look a bit rough to be honest so would sooner press my own in.

rocker b50 __159.jpg Half of the tiny shoulder on the inlet rocker ball end is broken off. Anybody seen that happen before? Overly pressed when made?
