Default 2nd gear difficulties

When shifting into 2nd gear, if I dont kick it in hard enough, it won't go into the gear. It's like its kicking it back out. It's loud and painful sounding when the gears are grinding when it kicks it back into neutral. No other gears do this they are easy to slip into. Anyone have any ideas or exp with this? Are my shift forks bent?

how long has it been since you changed the oil? whats your oil level like?


yes you could have a bent shift fork, or maybe a wore out shift drum, but i'd start with something small like changing the oil. my bike shifts a lil harder when my oil is older.

try that first, then go from there.

I changed my oil 1500 miles ago. It is at the correct oil level according to the peep hole in the crank case. It's still a nice light brown color.

Also, when I put the bike in gear and go down the street and then stop and shift to neutral and let the clutch out there is a slight vibration that I can feel and I can actually hear it too.

I am having this issue too. It started a while ago, and first thing I did is changing the oil.
It did not work, and the clunky noise is still there.

I have taken the bike to the garage, and they said that the noise is normal O_O
I guess the shifting fork is worn and bent and this is the reason for the noise.
Fixing this seems to me like it is expensive, since in order to reach the gearbox, you have to remove the engine. At least, this is my understanding.

Maybe someone could shed some light on this.

The shift forks and shift fork drum can be serviced without removing the engine. This is what my 954 manual says.

You mean, they can be replaced?

ya, they can slide out behind of the clutch.

its possible that you could need new drum, shift rod and fork.

but you'd have to take the clutch out, and the oil pan off.


as far as the vibration that you can feel and somewhat hear when you let the clutch out in neutral - that is perfectly normal.

I agree with Conrice on the sound made in neutral, correct me if im wrong but isn't it doing this because everything is probably just freely spinning without added force of being in gear?

Try adjusting the shift pedal. Usually lowering it some helps. Your foot has a limited range of movement and if it's too high, you aren't able to lift it that last bit it needs for a smooth shift.
