93 GK76A no longer drops into neutral

[Otaroko]

Hi guys, bought this about a week ago and finally got it up and running today! Ran into a problem though as I jumped on to feel out the bike.
-Bike had been running for about 15 minutes
-Clutch lever in, shift to first and crawl the bike forward a few feet to get a feel
-Clutch lever in, upshift try to crawl a bit, but bike feels like it going to stall so clutch lever in
-Try to downshift, shifter hardly moves up (it's at this point I cut the bike off)
-Now the bike will not upshift either, rock it back and forth a bit and bike upshifts and downshifts
-But will still not drop into neutral whether On/Off
I'm lost here guys. After extensive googling most have reported a bad clutch fork.
I eventually put it away after about an hour of trying to get it into neutral.
Thanks for any pointers guys. Got a service manual coming in from a bike shop here in a week,
so I'll be able to really start ripping stuff apart if no one has any ideas.

Oh yeah, hello from Japan!

Hello and welcome to forum :),

When i first bought my gk76a i always had trouble getting it into neutral. i came from a bandit 600. It always struggled to get into neutral with engine running, used to just stop it in 1st. but after abit I got used to it and find getting into N alot easier. getting the hang of it. Thats the simple explanation from me anyway.

when your riding do you have any trouble changing gears? ive gone to reverse shifting (up goes down and down goes up) for ease of shifting.
try and ride it if possible and see if it still happens.

or it could be were the gear lever is attached to the engine. i found if its off a tooth it really struggled to change gear because it wasnt getting the full movement.

any pics of your new beastie? :)

hello & welcome too! you're from japan??
normally, after engine is off, it can be easily shift back to netural... or before it comes to a stop, hit it to netural fast. mine's like that. try go on 1st 2nd gears, let the bike move off, kick to netural when its moving.

Hi guys and thank you. Unfortunately I dont have any pictures yet because the previous owner let the bike sit
for almost a year. Its rusted and has a fluoride looking deposit over everything, we call it Oki crust here. On top of being dropped and cracking the clutch cover which I just finished fixing up. So what I gather is that you can start your bike even though it's in gear with the clutch lever depressed? Mine isn't like that I believe. Unless I have the Neutral light it wont even crank.

or it could be were the gear lever is attached to the engine. i found if its off a tooth it really struggled to change gear because it wasnt getting the full movement.

When I get the manual in I will see what it says about adjusting that lever. It does seem a tad loose.

Like a rolling push start? You can do that on these? Interesting... Im worried that it will shoot out from
underneath me so I didn't attempt it. Though the thought did cross my mind regardless.

you can press start in gear 1 with clutch in. but please check your sidestand for the sensor wire. if its there, you have to kick off the side stand, otherwise there's no way it can start, its actually a circuit, you have to kick off the stand to make the circuit complete.. its a circuit with 2wires, you can just join them, keep them in the seat, mine's like that. if it doesnt have the wire there, you can clutch in, 1st gear, press start with sidestand support. understand?

the clutch lever can be adjust @ 2 points. if both points hit its max & its still too loose, you have to get a new clutch cable already. you can push start the bike. i never tried alone as its not really easy if you are not tall enough. i've tried with friends 3 times, with 1st, 2nd, 3rd gear. 1st should be the most dangerous as the sudden start is hard to control. best is 3rd with friend pushing behind, with what he called motogp style: rider stand & butt hitting back the seat in fast motion, starts it easier.
check your sidestand, most likely, there's a sensor wire. kick off the stand, try start again.

okay, thats my sidestand sensor wire. just found it recently when some mech kept it below the tank with the wires connected. i kept it nicely cable tied under my rear. the other is the wire's connector's end. just in case, you need a pic..

I always thought this

was only when my bike didnt start after i did a top end rebuild i decide to try to bump it.
As ben said, i found it alot better to try it in 3rd gear.

Put in 3rd, hold clutch lever in, give it a run about 5-6 bike lengths and let the clutch out and when you feel it trying to start bit of gas and pull the clutch lever in quick again. :)

Hi there
I sounds to me that the gear level won't return to the centre position when you move your foot away is that right?
I so it could be the detent spring under the clutch cover that's broken or weak.
It helps to return the gear lever to it's middle position and if it's broken the gearbox will think it you still have your foot on the lever and won't select the next gear.
If the bike has been sat for a long time the steel clutch plates might be rusty and sticking in the basket causing problems. just give it a good ride as that sometimes helps.
