i have a servo powered powervalve and wanna no what will happen if i play about with it im just looking for more power really and jw what i could do with it aprently its set up how it should be evenly in the middle but id like someone to tell me how it all works if it s not to much hastle :) i take it it works on air?
The powervalves purpose is to lower (close) the height of the exhaust port at lower revs and raise it (open) at higher revs. It becomes fully open at 6krpm.
The idea is to stop the loss of mixture at lower rpm that happens through the exhaust port when the piston is coming up fast enough to block it off(on a normal 2 stroke engine without a powervalve). The mixture has a chance to escape and the power is therfore down at lower rpm.
The powervalve and servo is the best way to have it. By the time you get to 6krpm your valve is fully open and you are getting full power.
sounds stupid, how do you adjust the power valve on the DT, is it the cables that are outside the PV system. like you can spin the nuts on it, does that adjust it? so if i was to fully open it 100% would i need to twist them a certain way?

Contrary to my previous post on this thread the powervalve actually starts opening around 6krpm. It will obviously stay closed until the powerband kicks in ( which is the point at thich the piston is coming up faster enough to block the exhaust port in time and prevent the loss of mixture). From there on it continues to gradually open until optimum power ( 10ishkrpm i think).
maniac, if you want the valve opend fully then you can just turn the ignition on, the valve will do its set up cycle and then settle in its fully open position. Then you can dis connect the servo from the main loom with the multi connector clip and the single bullet connector. Doing this will just reduce the power in the lower end of the rev range and the powerband will kick in harder at 6krm. This wont be more power as the valve isnt prevent the escape of mixture but it may feel like it is purely by comparison to the previous 500-1000rpm leading up to the poweband.
It seems the zeeltronic powervalve controller and CDI units would be the best option as you can alter the movement of the valve in a very precise way.
