    Cant see pinning the pv would be a issue mine 95 model didnt come with a servo and the pv is pinned wide open on that and its covered 600 miles in the last 3wks with not a single problem

      @andrewj1680 no maybe it won't but it's designed to have a working powervalve so you can't expect it to run perfect if one piece of the puzzle is missing

        Ok so i have a S reg here that ive bought to rebuild the pv as you can see has been pinned it pulls nice and strong every gear to the point it comes off the clock yet i dont have the same issues as above and the only difference is i have a standard front pipe

            Well it's always to get the bike completely stock before diagnosing problems.

            Bike is always going to run better with Powervalve

            Don't see why you wouldn't run one.

              Totally different bike to ride without, the powervalve hits so much harder when it kicks in, the servo just smoothes out the power delivery i think but definitely prefer it without but each to their own i guess

                The problem is the exhaust was perfectly fine before I did the rebuild power valve kicks in perfect up to third 4ths sluggish 5-6 no power at all starts to die same thing happens on peds if theirs not enough fuel it won't pull

                  @andrewj1680 Absolutely mate.

                  No arguments there, it's an absolute riot with the powervalve switched off.

                  But the bike performs much better with the valve.

                  It's why I like old school vtec civics, the ragging factor haha

                      @declan More performance with the servo, much more fun with it pinned.

                        The reason it feels better in the top with the PV pinned is because the difference between lowend and topend is bigger. The bike is really sluggish in the low revs.

                        With a prperworking PV, you get the best of both worlds, and going WOT in high revs, theres no part of the PV visible in the exhaust port, so no restriction at all.

                          @Jens-Eskildsen Absolutely, unless you have a DTRE CDI where it closes the port at 10K RPM. But earth the green and black wire behind the clocks and BOOM! Full power. Easiest bike to derestrict. It's like the Japs knew 😄
