no..I do this all the time, the only time the car gets a jump is when the idiot on the bike is in 5th/6th gear I will be cruisin along in 3rd with a little whine in the motor then when its 1,2,3 horn blows I drop it to 2nd and stomp them quickly back up to 3rd and then 4th and its over, I'm at 160 the car is way behind me.....I dont recomend the 2nd gear quick drop to anyone running taller gears, as it may just put you on your arse! i have stock gears still...well 18/43 on my gen 1 because i like it that way(stock for gen 2)
