    @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.

    @calum I've had 12k a couple of times. Earthing that cable transformed it

    Street Triple R '11

      @finnerz89 Yeah sick, the DTRs though - are different sadly.

      DTRE/X use a non Restricted CDI.

      2002''s are doomed to 8.5k.

      Keep it real

          @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!! πŸ™‚

              @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.
