I weigh about 340, and have limited racing experiience. I went 10.41. I only cut a 1.8 60 ft. My times were getting better through out the day. I know that w. a little experience, I will be able to run faster even w/ my big ass on it. I let my 145 lb buddy jump on it, and his first pass launching at 2500 w/ a 1.7 60 ft ran 9.67 @ 149mph. I was pretty impressed. Only mods were Lowered, strapped, and tsukigi pipe. He seemed to think that with a couple more passes he could have got into the low 9s. Had no power commander or clutch mod.
Bike now has air shifter, pcv, clutch mod, shinko, and swingarm is going on this weekend.
