      @declan Yeah should pull to around 12 mate.

      @Mitch_350z So long as its flush with the exhaust port that's the main thing.

      How does it ride now?

            @calum it seems to ride better when pinned but still only does 65 max and doesn't pull too well in 6th?? Struggles a little to rev up to but don't know If this is because of the pinning??

              @mitch_350z It shouldn't pull well at the lower RPMs, but past 6 it should pull hard to 12. If it doesn't then it's not the powervalve causing the problem.

                @calum ok thanks mate I'll have to do a bit more digging, just out of curiosity my other dtr I had was also a 2002 but had a 3 wire servo rather than the 5 wire this one has?? What difference does this make??

                  Everybody has to remember that 99' onwards 3RM DT's are CDI restricted to 8,500 RPM...

                  So, don't expect anything like a 3 wire servo Pre 96' model.

                  Keep it real

                    @darty The DTRE's are not restricted to 8500. The DTR's may be.

                        @finnerz89 Well, I wouldn't say WAY past. I think it's 10k. Because the Powervalve closes then and then it really struggles. But it's as simple as earthing the black and green wire then you get full power.

                            DTRE/X use a non Restricted CDI.

                                @cyber-ninja Tell you what, it's said that there were some 3RM CDI's that were Unrestricted from factory for last model 2003'

                                I can't remember the CDI code, if you had one, that was pretty rare!

                                  @darty I can't answer that for you as I sold the bike, but if it was an un-restricted CDI then yes I was very lucky indeed!! 🙂

                                    @darty could this be as simple as swapping the cdi for an unrestricted one or is this not possible??

                                      My brother had a 2001 DTR and it was slow as fook.

                                      Although once derestricted it went like stink.

                                      Pretty sure he swapped out the CDI though.

                                        @calum do most still have the reed valve behind the clock or is that only for speed not revs?

                                          @declan I believe that it's a sensor which forms part of the de-restriction system. It monitor's RPM's and when a set limit is reached it retards the CDI/engine from going any higher. Hence if you unplug the sensor then in theory your engine is capable of reaching it's highest maximum RPM.
