Morning all,

I inherited a K2 with 56k miles on her. Its been laid up for the past 5 years in a heated garage and started regularly etc. Previous owner maintained and treated her well.
But in second & fifth gear she spins/slips on opening up the throttle. It doesn't jump out of gear, it just slips. I was initially thinking it was the second gear gremlin but now that it happens in fifth also, I'm not so sure.I've given her a general service as well as fitting new parts to the clutch slave cylinder with the additional seal and fresh fluid. If it was the clutch, would it not slip in other gears also?
What do you guys think ? All advice suggestions welcome.

Well finally got round to sorting this. I found 1 bad shift fork, gears look ok. I was expecting it to be worse.

As you can see from your shift fork, your gears have jumped badly, and the solution is not just changing the shift fork. IMO.
Take a good look at your gear sprockets.

Those sprockets in my picks are badly damaged, but they will be ok after 4 to 5° "under cut" grinding.

kquacker

Yes I agree. The shift fork damage has to have an effect on the gears or vice versus. Although mine didn't jump out of gear, I'll err on the side of caution & get them undercut.

Good advice T24 👍

Yep it was a problem in first models. I had mine undercut and never had an issue since.  :clapping: :clapping: :clapping:

After undercutting gears do they need to be re hardened

@Imola
Nice first post it might be worth heading over to the bar and say hello .
As for the 2nd gear issue
The problem only affected a few k2 bikes(Suzuki upgraded the gear on later bikes )
Do you have a problem the 2nd gear issue made it jump out of gear .
Other things that can a
Effect the gear box are wrong oil,
Sticking clutch slave cylinder and or pushrod and gear leaver being fitted in the wrong postion
If your taking the gear box out it might be easier,cheaper and better long term fitting a 2nd hand  k5 onward gearbox .
Good luck  :cheers:

I once had a 2nd gear issue. Was in a hurry, pushing on. Came out of roundabout, thought i was in third, kicked her back, front wheel in air.  Guess i was in 2nd, sure wakes me up.
