The problem is that the last thread about this company was from someone that sent them money but has gotten not response. Sounds like there may be trouble with the honesty and continued functioning of this resource. Caution is advised

Question?......Is the pin in the middle of the valve supose to come out of the middle plate?Im in the process of cleaning my valves and one came out when i pulled it out of the exhaust port.

No...the pin that is mounted into the middle component of the pwer valve assembly is supposed to be permanently installed! This is what the Fischer Powervalve companies goal was/is...to mount the pin in a way that prevents the inherant weakness to occur and prevent engine damage when the powervalve falls into the cylinder and goes "kaboom"! It's a good thing you found this...that was a close one!

I heard some say, that Aprilia solved the power, at the newer rs250 models, 1998 started

Is this true?

When I first bought my bike in the fall of 99 a racer told me to replace the PVs each season as they had had a failure, however, Jay at Mototek said that this was over-reacting. I have almost 4000 race miles and three rebuilds on this engine and there is absolutely no sign of the PV problem you described. I would think that replacement as frequently as you describe would be a little bit of over-reaction...and expensive!

Digging this up to see if anybody has experience with the Fischer PVs in the four years since this thread started.

USD$150 is a hell of a lot better than the $800 for Dave Cooper pieces.

look at www.2takt-forum.de (http://www.2-taktforum.de) if you speak german, they still go pop now and then. valves. I'd go for the DC-valves.
