can anyone answer this question

[waddle]

does anyone know who installs the actual power valve on the power valve cylinders?? does pro x install the valve or does the engine porter (esr,duncan,ct) install the valve?:ermm:

In my case, it was installed by LRD.

I think L.A sleeve also sell their cylinders with the PV already installed.

well my question is i have a pro x cylinder,,im not sure who did the port work, but the power valve is broken, so does anyone have any clue to where i can buy replacement parts for the rotax valve????

I have seen a pic of an old Duncan powervalve motor with a rotax. You might try them.

If it's a Pro-X cylinder, have you tried asking Pro-X directly?

I know lots of race companies, like CT, LRD, ect, many of them don't manufacture their own cylinders. They use Pro-X cylinders, then add their own custom porting. So at that point, probably any of these aftermarket companies would also be able to service the powervalve, or give you replacement parts.
