Hello riders !
A Long Shot...
My engine is running lean and lacks power. It won't rev up and lacks torque. (between 50 and 100 percent of max power).

(good info)
The spark plug looks Ok but it is white which indicates that the gas/air mixture is to low. The carburater is fitted with a 109-sized Main Jet.
I bought some bigger ones, sized 110, 115,120 and 125.
110 would make no difference.
Which one should use. Trial and error - puh - dismounting/mounting....
Any suggestion ?
