  • clutch

    thinking about rebuilding my xj's clutch this winter, thinking about all new parts. who would be a good supplier? i noticed it slipped under hard acceleration in third gear, also you barely have to pull in the clutch lever to disengage the clutch. maybe can be ajusted out? thanks!

    I would try adjusting it first. A lot of times, new springs will fix the slip.

    Clutch parts reasonably priced, XJ1100 uses same clutch parts as XS1100...

        Hey Blkbird,

        As Phil stated, it's mostly the springs that seem to get worn/sprung, and can contribute to the slippage, but it does sound like it's adusted too tight...both at the handlebar, as well as the engine. You need to get the procedure from the manual, and first loosen it at the handlebar, and then perform the adjustment at the engine side, and then readjust the clutch lever for the amount of travel you want.

        The clutch is a little tricky in the handling of the star pressure plate, they are easily broken if not properly reassembled. You can find some good photos and info about this in both the Dremel 1st/2nd gear fix tip, as well as the extra steel plate mod tip.

        Varnish can build up on the frictions and steels, using some Marvel Mystery Oil in the engine oil, slowly and gently idle and bring to operating temperature, run thru the clutch and gears on the center stand operating the clutch, etc. for 5 minutes or so...fan blowing across engine, no hard throttle revs and no riding/load on engine. Then drain oil and change filter/oil. This along with the proper adjustments, and use of proper dino oil, it's been shown that full synth as well as oil with friction modifiers can contribute to clutch slippage on an already weak system ie. weak springs.

        If you still have slippage after the adjustment/cleaning, then you can probably justify tearing into the clutch to replace the springs with Heavy Duty ones, but also checking the frictions with a micrometer(2.80mm min out of 3.0mm max), and then replace if found close to the min.

            Miles

            How many miles do you have on your clutch? Like TopCat said, probably just needs an adjustment and the cleaning he recomended and then back to all good Not starting an oil war, but "I" would get an oil that doesn't have the auto add's that "can" cause your clutch to slip (It happened to me on one of my bikes with just one oil change, clutch was fine, new auto oil, clutch slipped badly) Cheap, Cheap insurance

                Clutch

                I am guessing, clutch still has a lot of life left in it. It could be shot with how you explain the adjustment is if it is so tight it caused slipping, that will burn up any clutch But since you said you just started to note the slipping, I will bet, a good adjustment will fix it fine Good luck with your bike

                  Use ths Castrol 4T and replace the clutch springs with these and problem solved. With a proper adjustment of course.

                    Just guessing?

                    I am just gussing, but if you have 0 slack on your clutch cable, adjust and see what happens I would bet new springs won't be needed, cost nothing to try

                      Adjust ALOT of slack at the cable, then adjust at the throw out bearing, then re-adjust at the cable.

                          There should be 2 to 3 mm of slack between the lever and housing, but 1st, completly loosen the cable and adjust the presure plate, then lube the cable and adjust the slack there, I will bet it works like new

                            Clutch

                            For the Presure plate clutch adjustment, remove the cover AFTER loosing the cable at the handlebar. Losen the PP locknut, turn the adjustment screw till it just touches the PP, then back out 1/4 turn, tighten the lock nut, replace the cover. DO NOT pull the cultch lever at all during this procedure. Then adjust the cable to 2 to 3 mm play at the handlebar, all done

                              and so i adjusted my clutch today, it engages closer to the grip now, still clunks when put in first and most likely always will, rode it two miles seems to be working fine no slipping so far. thanks for all those who offered advice you guys rule!!!
