shift drums wrong position (KZ750 Shafty)
21 Jan 2020 09:05
hi all! assembled the whole bike, but when tried to change gears, nothing had happened, obviously i put the shift drum in wrong position. the question is can it be cured with a little blood (without splitting the crank case)? thanks heaps in advance, disassembling the whole bike would be a fucking disgrace for me pardon my french

When trying to change gears were you able to shift from neutral to 1st gear? If so, that's all the tranny is supposed do unless the bike is running - Kawasaki built that in as a safety device. Ed

also i do know that i didnt installed a 92081 spring coz i had lost it somewhere. i dont think its crucial coz ive never seen such a spring in other drive shafts and the spring looks weak... but i might be wrong?

Every shaft drive bike Kawasaki has ever made, including the current Concours, uses a coil spring in that spot. It keeps tension on the two parts of the shaft so that they do not make clanking noises as the suspension moves up and down, also protecting the spring loaded retaining pin from damage or breakage. It is unlikely that Kawasaki would have gone to the expense of designing he collar for that spring and the expense of installing it and putting it in inventory if the engineers did not think it was necessary.

one half shaft is held by a circlip, another one by a nut, i cant imagine how they can hit each other and what kind of pre load the tiny spring can provide, its like putting a spring inside a car drive shaft/
and what about the blocked rear wheal coz of over tightened nut?

By all means, leave out any parts you deem unnecessary.
When a rear wheel locks as a result of tightening the axle nut, the most frequent cause is a missing, incorrectly installed, or incorrect spacer. Pay very close attention to the order and orientation of those parts when reassembling.
