1st gear to 2nd gear jerk

  You will have to take it appart

[Emil]

Damn. 
Do you think I can take the clutch out without a clutch holding tool?
And as I a probably also have to take the clutch apart - how hard is that really?
I have seen a video on youtube where a guy holds the clutch with a vice and presses the cover down with his hands while unscrewing it? So I am wondering how tough that clutch spring is... (maybe it was superman).
Any suggestions?

G'day Emil, if you have someone to help you, get them to sit on the scooter with the rear wheel on the ground and hold the brakes on while you undo the clutch bell nut, then you can put the scooter back on the stand and remove the clutch. The hardest part about opening the clutch is finding a spanner to fit the nut, mine was 39mm. The pressure on the spring is not a lot, but yours being a 125 might have a stronger spring. If you have a vice, use that to gently clamp the clutch while you loosen the nut. When you have the nut loose you can put the clutch down on the table or floor and one of you hold the spring pressure while the other removes the nut, then carefully release the pressure on the spring. Once you have done it once, you will work out what is best for you. Good luck and happy modding.

Hello,

Finally did it - and the jerk is gone!
It was indeed caused by dirt in the clutch case or to be more specific by oil in the clutch outer case and on the clutch pads.
It looked like the oil leaked into the area from the inner bearing. There is an oil seal n the clutch case that prevents oil to leak into the area where the drive belt runs but unfortunately nothing that prevents leaks into the clutch area and that means that the problem will almost definitely re-occur.
Since this would be a manufacture weakness I think fixing it should be covered by the warranty. Bu then on the other hand I feel like it's better not to bother since I would probably be told that it happened because I abused the scooter (or some other stupid excuse); and I would end up having to pay for it.

Anyway - here again for everyone with a 'jerk in the scooter':
All that needs to be done is removing the clutch outer case (in the rear) with the help of some sort of flywheel holder (sitting on the scooter and pulling the brake wasn't enough in my case), and cleaning the outer clutch and the clutch pads with brake cleaner. Don't get the cleaner into the the clutch assembly though. Sanding the pads a bit after cleaning is also a good idea. The clutch assembly itself doesn't need to be taken apart.

Thanks, I want to try my luck with cleaning this weekend.
How did you clean it? Did you remove any parts but the cover?
Can I spray brake cleaner into the clutch case or is this not a good idea?

You need a rough brush and/or air compressor.

[Emil]

Mmh - I don't think an air brush would have been right. That would blow the dirt only around, if anything at all. For the clutch pads a tooth brush was fine, for the outer clutch I used paper towel.

Actually I would love to mod my scoot a bit. But then on the other hand I don't want to spend money if I can't be certain of the results; and also I generally rather ride then spending my time in the garage. Maybe I will change to something bigger next year like a little dual sport. Although that might get me into trouble when parking it on Boston's sidewalks. The new Genuine Blur 220 also seems pretty cool. Just wish the price was cooler...
At least for now I got rid of that damn jerk and the unwanted wheelies. Next is replacing the fork oil and getting rid of the front wheel wobble.
