Zang said:The full Akrapovic is FAR from stock. They are worth anywhere up to 17 HP from people's numbers (w/o the power commander). I've seen 158-160 on here all the time but all the bikes within 300 miles of me have ALL dynoed at 145 or less stock. From everything I've seen on the dj150 & dj250 the only real difference is the ability to brake tune and do both readings but both have innercia dynos and if both have upgraded software, there is supposed to be NO difference in the innercia dyno readings (according to dj).
1287s typically run stronger than 1270s. Depends on what all is done to the motor, and who built it. More specifically, head work and cams. 15hp difference is possible, but only if one has the head/cam set up, and the other doesn't.Cause there is no way my buddies 1290 motor is actually up almost 15 ponies compared to my 1270 motor bike.
