sorry for my bad english and thx for reading

I expect you have done it by now, i have no knowledge of the 125, but, this looks like the cable that operates the power valve.You may need to mark position before disassembly. Anyone else ??

hey

yea i found out its the powervalve i only need to figger out how to disinstal it XD

thx for reaction

Ok the Euro models are a little different to what we get out here but here goes anyway!

1.Place a small amount of nylon rope bundled up in the exhaust port to keep the power valve from moving!

2.Very carefully undo the small bolt that retains the cable wheel that you see in the picture.

3.Slide to cable wheel off the powervalve shaft, you will probably find that the power valve shaft is keyed so that the cable wheel will only go on one way but if it isn't, (hence the nylon rope) mark it carefully with a texta & note how much spring tension is applied to the shaft (if any)

4.You should then be able to remove the cylinder!

Note: I usually clean the power valve when I have the top end apart as I think it makes sense to do it at the same time while you have it apart!
Preventive maintenance is a very good idea! There is nothing glamorous about being stuck out on the trail with a dead bike! It's not fun!

Hope this helps!
