I don't know a whole lot about this so here it goes. I have a 06 Crossfire 700. I only go out west 2 times ( that suck's ) a year and love it. Anyway's, when I am out there the sled is really doggy off the start. Seem's like I am riding a 400 fan cooled rather then my 700. I know this is because of the alt. change. Once the sled get's rolling it rip's just fine. Would I be able to run stock M7 gear's and see a difference. I would also like to possibly leave them in for around home which is northern WI. If I am right the m gear's will give me more lower end torque. I do some 660' drag racing and think that would give some good pull off the line. Any info. would be great. And are they a pain to change out?
