  • RZ Power Valves

    Do you have to remove the barrels to remove the power valves? if so can it be done by removing 1 only?

  • #2
    um there are two half moon's that hold the PV's together but both barrels have to come off as each pv split from the middle so one half comes out from the left the other from the right of each barrel,

    if only one pv needs attending to then you only have to pull that barrel off but don't forget the half moons between the barrels that combined the PV's as one

      So you are saying that I can't just remove 1 barrel???? with 1 barrel removed wouldn't the barrel still fitted be clear to get to both sides of it's PV? I trying to do them both without to much work.

                Why the left one ritza? is it easier to do it that way. I have found out that the seals on the 2 opposing centre PV's shalfs are the problem.. Now where is nath?.... has he fitted the "o" ring and shaft seals without remooving the PV's? I can't see why it wouldn't be a problem.

                  Left one has the pulley on it.

                  Nah, I haven't done it without removing the PV's, going to be a pain I would think.

                  Honestly, you'll probably frig around trying to shortcut and end up having to do it the hard way anyway, I would just do it the long way to start with.

                    you can just remove the servo unit and lock wire both sides full open all the time

                        Not a lot of room there.. good luck though.

                        Might be enough gap to pop the o-rings off and on.

                        IMHO if your o-rings are shot you should check the castle seals also.. not to mention the condition of the bush. I'd want to be putting some form of lubricant on both also.

                          he can always restore the PVs properly if and when he rebuilds the top end

                          imho no point ripping the barrel off just to fix the power valves.. especially if you are a noob who is likely to miss lining up the rings correctly or something else equally as catastrophic and dumb L:/

                            the long screw that joins the pv halves together !...the allen key head faces that side

                              Well nath and everone else it can be done without removing the power valves. Its a quick fix at the moment so the exhaust gases don't come out there when the bike is running. Looks shit smoke comming out of the front of the engine and not out the exhaust.Once I got the cross over clump off it was quite easy, lucky the previous own put hex bolts in there.
                              So whats next to fix on this bike?
