Concluded that he master cylinder is toast, looking for some on ebay, a new one is £160 :/
Clutch correct?
what exact year/model is yours? Looks like there's 2 part number depending on the year/model for gen 1 tuonos.
Sent mine for its mot. Shockingly it failed on the tyre valves but they replaced them for the cost of the valves as I kitted myself out with them when buying all my gear which cost me a small fortune (first bike).
Mine is a 2003 bog standard 'Fighter', although I read somewhere that all clutch master cylinders are the same gen 1 and 2, gen 2's certainly look exactly the same.
Didn't know that was a thing when it came to MOT. How do tyre valves fail MOT?
yeah looking at it, ti's the same part for gen 1 and 2, and falco's. There's a few on ebay, for £70-80 - I'm sure there must be a rebuild kit available if it's just a seal that's gone.
