were would be some common places to check just the boots

its kinda boggy wen i take of after that if i get on it and stay on it throught all gears its fine if im going about 1/4 to 1/2 throttle and punch it it hesitates and sometimes back fire and then will take off like a bat out of hell this is with the 270's and the needle on the 2nd slot
