well i finally recived the 57mm (999s pipes)system for my bike yesterday and went and fitted it before a few dyno runs
and 138bhp at the back wheel and 145 at the clutch. Thats a 5 bhp rise with just the exhaust fitted not bad as im still using the origional 999r open cpu im still waiting for the Fuel Adjuster to arrive .
does anybody else with a 04 999r have any power curves standard or non standard?? ill get mine next week and post them up
i had pc3 fitted with my 1st service and dyno set up with jhp see graph john hacket said my exhaust is restricting the true power i can get he said i need one of yours and andys 57mm exhausts before i lash out 2k on one can someone post a graph with one on thanks
