i posted some details of fuel consumption on my 2000 gsx750fy, I may have been **** when i did it!!!!!! The front sprocket was changed from a 15 tooth to a 16 tooth, not the way I had described it. I still get up to 330 kms per tank cruising at 110-120, a few drops of NULON or Slick 50 seem to increase the gas mileage, cheers.
