hi,i went out on my rmx 250 today and after about an hours riding it went alot quieter and slower midrange,i thought the tailpipe was blocked as i just fitted an rm 250 system to it or powervalve problem so first i stripped the exhaust system down and everything was free flowing,i then took the powervalve cover off and found the 8mm bolt had come loose,when i pulled the actuator rod up to see if it was connected it had no resistance and loads of play on it,i connected it all back up and took it for a spin and everything was ok,what i need to know is where can i get a diagram of the powervalve mechanism etc from as i would like to find out how it works in behind the waterpump because i dont like the play in it,i reckon an rm 250 one would be the same ,any advice and suggestions welcome,thanks.
