    I need help/advice before Snett next Sat.
    Just test rode the RR6 for the first time and am getting clutch slip after setting off. It's ok in the drive, but the revs run away when I try to accelerate hard when on the move. I'm hoping it's just the Sigma wants setting up as it's supposed to be new when I bought the bike, but I've never done a bike clutch, let alone a slipper clutch.

    Can I just remove the left cover and check the plates with a view to figuring out how to tighten it up?

    You read my mind (or rather a post I picked up from 1000rr.net on a Google search).
    Yes I fitted chinese levers when I bought it, but have only ridden it for the first time today. I could swap the clutch lever with my RR5 road bike if you think it's that as I can't get to the original levers until my storage unit opens again on Monday.

    if my memory serves me correct when you take off the standard lever there is a removable plunger barrel in the lever which you need to remove and insert in your aftermarket ones. then simply refit the lever. hope this helps

    Wonder if I'm missing a bit then as I refitted the original plunger and barrel when I received my levers as they never came with any.

    As said you need to check the lever first, the sigma is a simple but VERY effective clutch, you can remove the plates and check them without special tools, you can adjust the slip but never needed to with a sigma clutch, without checking the lever no point checking the clutch pach condition and stack height.

    I have a Chinese clutch lever that does the same, however to the eye looks the same shape as my OEM one, there must be something that is out of shape on it.
    Prob the same with yours.

    If it has be sat months with the clutch slightly compressed could that not cause issues tho?

    Also had similar problem with my CB1Kr (using pazzo copies), the issue was the plunger was not fully located in the lever. Needed a bit of fiddling to get it to get the plunger home.

    Only noticed the slip when I gave it beans. Quite scary when I made my first overtake after fitting!

    Quick update. After trying 2 other clutch levers I decided to drop the bike off at the local garage to sort it as I need it for Snett this weekend. Fortunately I got a call from the garage to say that the plates are worn out and will be ready for collection on Friday morning @ £192.
    So a reasonable test ride home should see me sorted for this weekend :)

    think half of that would be labour,seems like a lot just to fit a clutch pack to me.

    I looked them up and they vary a lot between £50 - £125 for a set of plates. I guess the quality varies, but I just didn't have the time to get the parts and figure out how to do it myself before the weekend. Just a bit pissed with myself for not test riding the bike when I bought it.

    All sorted. Test rode fine, refitted the chinese levers and still rides fine. Now loaded up on the trailer ready for 2mo :)

    Re the bill, they chose to fit an EBC kevlar clutch kit @ £138 + £54 labour. They've probably added a little, but I'm happy it's done, hassle free, and I now know which clutches to use next time I need one. It was this one:- http://www.ebay.co.uk/itm/EBC-SRK-C...pt=UK_Motorcycle_Parts_13&hash=item46241ad645
