Message: [QUOTE="Lukee_RM125, post: 1424954, member: 123528"] Yo everyone, recently purchased an old 1990 RM 125.. when i first rode the bike i noticed it wasn't pulling as much as it should on the top end, like it wasnt hitting the powerband properly.. I'm new to the engine side of things so i got my mate to have a look for me to see what was going on inside. when we took the power valve cover off to our suprise there was no valves / acuator rod or anything inside !!! infact the previous owner of the bike had 'bodged' a mechanism inside the ports, in which case the valves werent opening fully, which i presume is why the powerband wasnt coming in properly..weve tried to rebuild it to how it should be but stuck on what the actuator rod connects to in the bottom end and how to assemble the governer! also there is not much compression in the kick, you can push it down with one hand but she kicks up first time easily, the piston and rings dont actually look that worn! HELPP! cheers. [/QUOTE]
