  • J1 kick start issue

    Started a quick little build up of a J1 bottom end i have had on the shelf for ages this arvo, got her all cleaned up and spent a bit of time with the points file cleaning up the splines on the kicker shaft and got them looking good then after fitting kickstart realised its not engaging at all sometimes(not like the clutch is slipping but not engaging whatsoever) spring not broken,returns fine. Gotta go buy a new impact driver as mine has gone walkabout, so i will rip off the clutch cover tomorrow and have a look but i'm just curious if anyone has an idea what its going to be when i open it up. I was only planning on doing a quick build of this motor (top end)and cant be arsed splitting the cases, otherwise i would've just grabbed a shaft from another donor motor. Anyone got any ideas?

    maybe missing a tooth on the gear?
    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.

      I bought a second hand motor with a kickstart problem. It wasn't engaging and it was only returning sometimes. Took cover off and the outermost circlip was missing which allowed the spring and metal bit to fall off. Pushed it back in with a new circlip and it works fine now.

            Jaimie was closest, friction spring jumped the circlip

            Didnt find any thing else nasty while i was in there, the shift star screw had backed out but that's it. Happy days

              Quick question on the above photo. does the thrust washer on the kick start shaft definitely sit inside the right crank case??? If so, I may have an engine or two to pull apart!

                    Surely not Diggs. Possibly 1 or two Zds��
