Hi I had a similar problem with my rc valves not following a logical pattern ,revving the bike in neutral the valves were all over the place,'twitching' then I took the chain off and put the bike in gear and revved the valves then acted in a more logical manner. on the road the bike works well so i can only presume with my limited knowage that bike needs to be in gear rather than neutral to run the valves in the correct manner. see if that helps ,im sure someone on here can come up with answer
cheers Malc
