hey all i own an r125 and it has developed a reving problem when under load.
its a hard one to explain but.....
when under load in any gear but most noticable in 3,4,5 if i pull the throttle back instead of it being a smooth brrrrrrrrrrrrrr from 4k upto redline it sort of stops and starts more like brrr,rrr,rrr,rrr,rrr,rrr if you understand me lol....
Ive changed the plug and it made it a little better and i have checked the air filter and that seems ok
the oil level is fine and is on the dipstick
does anyone have a clue what is causing this.
thanks
Jas
