    thanks bud i just remember when i first had it after i bought it bout 4 year ago and matey had it pinned open but dont know which way round 180 the power valve was pinned it had a stock expansion chamber and a aftermarket end can with baffles removed although he had purposely dented and crushed parts of the pipe leading from the chamber to the end can it pulled like a beast, although i was only 19 then and now i weigh a good 40 kilos extra , and i do realise its not a MX bike but surely i should be able to pop it up in 2nd or 3rd ? cant seem to get to do it.

      if you take exhaust off you can see the power valve and feel it its at the top turn on the ignition and let it do its cleaning cycle and it should rest fully open so when you slide you finger into the exhaust opening it should be flush and smoove at the top if not you need to ajust the cables till it is and then you check again buy turning off ingition and back on so it does cleaning cycle again till it right if that makes sence

          with power valve set up right you will feel the diffrence and with a few more revs it will pop up as when it hits 6000 revs the power valve will be fully open so make sure power valve is set right and plenty of revs it will come up no problems

              Removed baffles? it isn't a four stroke mate you need solid back pressure as to allow the supersonic sound wave to pressurise appropriately to allow the forced induction to operate.

                i dunno mate but it was alot faster than it is now acceleration wise. like i said no expert im a noob, i can only theorise that the dents he put in the pipe were to compensate for the baffles being removed.

                  you want it working and not pinned just make sure it flush you can try sitting further back on the seat to as that will help but as i said with it set right you will see the diffrence mine comes up from pull away and im 16 stone and tops out at 85 on the clock so im sure yours should do the same if running and set up right

                                      Your not going to find much extra power, get her jetted nice first,

                                      Raise the rear the ride height,, and gear it down (bigger sprockets) will help dramatically!

                                      Keep it real

                                        am i right in thinking that big one expansion chambers are restricted anyway ? i have heard so and i can see a kind of mesh thing near the echaust manifold but in the start of the chamber pipe
