It stills pulls at 9000rpm which for drag racing is fine but prolonged driving its too high. Right now I'm running the stock sprockets with 3:08 final gears. I'm looking for around a 2:80 or 2:90 gears. I think with those ratio's I would keep much of the bottom end but improve top speed a good bit. Normal for the Yerf between 7600 and 7800. A stock engine will quit pulling at around 7200-7300 rpm.
