Engine off should I be able to shift with no clutch

#1 Post by Martin_sa » Mon Jun 10, 2019 6:47 pm

So I have bought a project gs750 bobber bike that just needed the wiring in I'm a sparky by trade but no mechanic.
Wired it all all good but before I take it out I'm able to shift through gears with out the clutch when their is no key I. Ignotion? Is that right?
Also when I'm doing it I can't just straight shift I have to roll the bike to find it goes through the gears? I just wanna make sure Its correct before I take it out!
Thanks

Hi

Most bikes will shift much easier if the bike is moving

Hi.
Putting it in simple terms, the way gears mesh together is via dogs (small cylindrical protrusions on the receiving gear) and dog-holes ( slots about 4 times the length of the dog on the driven gear), usually 2 of each person gear. When you change gear a selector fork pushed the gears together to make those dogs go into the dog-holes.
When riding all the gears are spinning on their shafts - allbeit at different speeds, so the dogs slot in quite easily. At standstill only the driven half of the gearbox is spinning, so the dogs won't slot in as easily ( lots of bikes clunk going into first gear from neutral).
With the engine off & bike stationary nothing is spinning so there's about a 60/40 chance of the dogs and dog-holes lining up at any moment, so turning the back wheel a little helps line everything up.

So, yes, your bike seems pretty normal based on you description πŸ‘

That's the simplest description I can thing of without pictures/video. Theirs plenty of stuff on YouTube that explains it better and in as much detail as you want - The Workshop is one channel that I've used for odd bits of tech info.

Unless it's a Kawasaki . ( Well not all Kawasaki's ) They will not shift from first to second while static . They are designed that way to make it much easier to find neutral .

I can't speak for more modern Kawasaki's but many older ones including the ER5 have a simple device consisting of 3 ball bearings that sit in a groove on the gear shaft and prevent movement into second gear . As soon as the shaft rotates the balls come out of the groove due to centrifugal force and you can change gear .
