Recently ive noticed my 05 busa getting louder in first gear than normal. It seems like my RPM's are higher than what the should be when at a certain mph. In 1st gear im hitting 5500-6000 rpm at 35mph and in 2nd gear im hitting 5000rpm at 40mph. I hit 60mph in 1st gear and it was between 9-10k rpm. I recently change my gear ratio a few months ago from 14/40 (owner before me had a 14 on the front) to 17/43. Does this RPM to MPH sound about right? Ive been riding around with the new gears for awhile but hear recently is just feels like the power on acceleration is weak. I could be just tripping and this normal. I have new plugs and filter so I wouldnt think that would be an issue. Am I tripping or does this not sound right?
