  • TB Clutch slipping

    Hi All,

    I've recently done a changeover from 6v to 12v on my Gorilla with the Takegawa kit.

    I've ended up with a fair few extra revs and have been using them, well, somewhat enthusiastically. The end result is a clutch that is slipping.

    The bike had a tb 88 kit done by the previous owner - but all the info I have really boils down to a photo of a pile of parts - but includes some tb clutch plates.

    I've checked the lever to ensure it has some free play - and have pulled the clutch cover off and checked the adjustment there. Slightly better, but it still starts to slip once past mid range.

    Any suggestions? I'm kinda assuming it's pull it and replace the plates? How good are the tb plates?

      Honestly - I don't know. I haven't changed it since I got the bike (2 months).

      It's still pretty clean.

          Well, it would seem that oil isn't fixing this one.

          I am however pleasantly surprised that an entire clutch only costs about the same as whatever cross between Unicorn and Angel tears my Ducati required for oil.

          So - I've ordered one of these: http://www.webike.ph/products/543122.html and the special tool to get it out.

          Anything else I need or should do while I'm swapping it? Or a good guide anyone would recommend?

            Do you have any pictures of your old clutch basket and plates?

              Happy to take a few when it's out.

              The closest thing I have to a photo of them is this

                when you put it together did the plates fall into the basket or did you have to force em in?.

                most people lightly file or sand the edges so they dont bind because the TB clutch plates usually need it.
                You have two parts of brain, 'left' and 'right'. In the left side, there's nothing right. In the right side, there's nothing left.

                  Znut - I didn't actually put the clutch in - the previous owner did - so I don't know.

                  That pile of parts is from when he had it - its from a thread on here actually - and it's really the only way I knew (and, well, I guess I won't know for sure till it's apart) it had a clutch upgrade done. And I have no idea the life it's had.

                  I've had good experiences with the takegawa stuff I've had so far - so I just figured I'd try theirs instead.

                        Here is the Takegawa 02-01-0203 online instruction manual in Japanese: http://www.takegawa.co.jp/pdf/02/02-01-0203.pdf

                        Copy the text from the document into Google Translate and it will translate the text from Japanese to English: https://translate.google.com.au/

                          Thanks Jamie that's a huge help.

                          If I'm right - anyone who needs this in english in future should be able to just be able to click HERE and that should show the manual in English - but you'll possibly need to be using chrome.

                          And thanks for the offer of help MP - I'm not sure I'm going to get to it this weekend - hopefully I do. I'm right in town - just far enough away from the v8 protestors - but close enough to the v8's

                            So - ended up with more free time than expected today and gave this a go.

                            Firstly - I might have to change the title of the thread to "Slipping clutch" as I don't know that the bike had a TB clutch in it now. It was only a single plate, and I don't really know enough to say what it is.

                            Also - I found a few loose screws in, well, the actuator plate? I'm not sure that's what it is, but I'll call it that and the smart people can look at this picture and tell me the right name:

                            loose.jpg

                            Also - the Takegawa was a triple plate, whereas the unknown clutch was only a single. Big difference in thickness as here:

                            difference.jpgdifference2.jpg

                            Have it all back together - really was a non event so far and pretty simple. Thanks to all those that offered to help too.

                            I've only really started and moved it off the line to test it so far. I'll get it out later for a better shakedown and see how it is.

                              Not too much you can do with the single friction disc JDM manual clutch assembly except rebuild it.

                              What is the part number on the TB plates that you have?
