Dynod the RMX

[Rmxer]

got the bike dyno'd today after fitting the pro circuit pipe and found it to have 33.5hp @ wheels something was definatly not right and after working out the power valve wasnt opening properly we held it up with some vice grips and got 41.3hp @wheels (46 Motor)
so need to figure out why the actuator aint pushing the rod high enough to open the valve full. the power valve has already been rebuilt at the the gearbox end but gotta feeling it may have shat itself again! will find out tomo when i pull it apart!

hmm think my rm may have the same problem, as I took off the powervalve cover and it didn't open much when I revved it. keep us updated on what was wrong.

well this is the F**Ked up thing, of course when i take my bike to my mechanic today kick it over, rev the tits off it and the power valve is opening up fine! (have power valve side cover off). and now it seems to be flying so gona go for a ride in weekend and see how it goes. wierd how it wasnt opening up on dyno tho

sometimes they get a bit gummed up with old oil, and can take a while to get loose again...

There is a small bearing on the power valve actuator that if you have the wrong way around it will not work properly.

hmm may be my problem, as i did not note which way the bearing goes when I reassembled them. which way is the correct way?

Well if you are having powervalve problems, check that bearing out. Mine was the wrong way around. Now that its fixed the bike fucking flys.

reallly? so did yours sometimes rev out fine ? or was it always not working?mine seems to be ok at the moment..

It revved out fine occasionaly. Just wouldn't make any power in the upper rpm range.
