Kawasaki forks need a special tool It like a pyramid shaped piece of steel welded onto a shaft . it is put down the fork tube and locates into a square hole when this is in place it locks and stops it from turning when you undo the allen bolt at the base of the leg or do what i do is take the forks out and get a shop to change the seals |

Had a feeling it'd be a special tool lol, ah well looks like i'll have to make one haha. Being a tight yorkshireman I dont like paying for something I can do myself. Although I may bite the bullet n get a shop to do it. Cheers anyway ;-) |

not sure about the newer forks but if it has the allen head bolt that comes up from bottem side above axle like the earlier style front ends its an easy fix. put the spring back inside of fork and screw cap back on to keep tension on top side of dampner. then use an air ratchet or good impact to remove the allen head bolt if your forks are made that way . reverse procedure to reinstall if applicable

Hi, I am just refreshing my Z650 forks for the MOT. In the Z650 forks the internal pattern in the damper tube is a19mm double hexagon. To make a tool get an old 19mm / 3/4" wheelnut off a car wheel then drill it out to 1/2" and braze or weld it to a piece of 1/2" bar. If you do this both ends of the bar you can hold it with a spanner while undoing the cap screw in the base. I have had a good search for new bushes and have sourced some in the states. I sent the stancions off to A M Philpotts for hard chroming. Hopefully it will all go back together without leaks if I can find the right seals. Pattern seals are too thich preventing the circlip from going back in the groove.Any idea where to get the correct 7mm thick seals? BR, Peter |
