Yes ..... if they ever ever have any in stock. Great clutch, got one in my Mugello, not touched it in about 4 years since fitting it. Got AF 6 plate road in my RB, also no issues and been ragged up the drag strip about 30 times.
I actually got it from you Martin. I don't suppose you can get hold of one for me could you? Like I said I don't really want to shell out on a complete new unit.

Just checked and they're out of stock. Have you fitted it yet?

Yes, I've done about 6 road miles and the odd run through the gears on the engine stand in my shed.

After stripping off the side casing I've somehow fitted an 18 tooth front sprocket rather than 17. This is probably one of the reasons it's so flat in 3rd and 4th. I've replaced it with a 15 and gone with a 46 crown wheel. I'm hoping this will sort it out and give me the go I'm after.

If it feels like it is revvy its tits off then it is probably geared correctly, that's where the power is.

I'm pretty sure I fitted the Mid / Road NK. Hopefully it'll rev enough to get the best from the kit. If not looks like I'll be shelling out on a new pipe..
