OK. I finally got my bike up and running and recently got it dyno'd in. However, I am having a problem and need some help.
My bike is a 1995 900ss, converted to FI (1999 900ss ecu), 3 mm bore, 2mm stroke, ST2 cams at 108 lobe centers, Guy Martin full heads, open airbox, power commander. The first dyno is from when I first got it converted to FI with the ST2 cams and power commander. No head work and stock ECU. As you can see, it pulls to 8300 rpm with a hp of 92.4.
The second dyno is with Guy's heads and a remapped ECU. Run 008 is a full d&d 2 into 2 with no cross over and dyno 015 is with a spaghetti header and termi slip ons. It stops dropping power after 7800 rpm.
Why the drop? I am assuming that it has something to due to the flashed ECU. Sugestions? Also, anyone have a spare ecu (the sandwich type) that I can borrow/buy to narrow this issue down?
Thanks
Mike
