I just got rid of a r6 and my gsxr600 and bought my first sm. I bought the bike second hand, and when i did it had the 3x3 mod done to the airbox. This job was so porely done it looked like he cut it with a butter knife. So i cleaned it up and riveted some metal meshing over the top of the whole,looks really nice but at the end the whole was about 4x5 inches. I also put a k&n air filter in it. and the bikes has a full yosh exhaust. How do i know if i jetted the bike right and it is working to its full potential. any help or pointers would be great. thx
