Hi,
We have a KTM 125 EXC that after renovated cylinder behaves strange. It runs as expected pn lower rpm but on higher rpm it looses power, most of the times at least , a cople of test runs i has been running just fine. I'm suspecting the exhaust valve but when inspecticting it it seems to move correctly. How would a bike run if the valve is not operating correctly? I don want to take the cylinder off is there could be some other cause... ( have tries with a new spark plug).
Cheers
