i have a few suggestions,first get the clutch straightened out,otherwise 60 ft's and 330's will be junk,dont let much if any air out of the back tire,30 + lbs will be fine (sticky track)
avoid the water box,and just a quick spin of the tire should be fine,i would also put the 17 tooth front sprocket back on until you are getting very quick consistant 60 ft's,high staging rpm is not nessacary,because if the throttle and clutch are working together the revs will do a rapid rise and 60 ft and 330 will let you know how hard on the gas you are,until you have pro level skills,low tire pressure,big burnouts and stratosphiric launch rpms are dangerous and hard on parts,the high tire pressure will teach you clutch and throttle control,and should cut down on wheelies,a air shifter is also nice to have you can hit the button to control wheelies rather then closing the throttle which kills et's
