For those that have changed to 3.37 gearing.
Do I have to redyno or change anything if I change to the 3.37 gears?
Will the torque and horsepower come on at a different rpm range?
Is this a logical question?
Trying to get more low end torque.
BTW, Does anybody know of a good SERT Tuner around the Memphis, TN area?

Thanks,

Can't help on the SERT tuner in Memphis but you don't need him just for the gear change. I did the 3.37 andlove the stonger pull but find the higher revs on the highway pretty annoying and I can't bury the speedo anymore.Tops out @ 118.

 

No, you will not have to Dyno-tune the bike...........you are not doing anything to effect the AFR or timing of the motor.

It will be a different drive ratio, so the power will "feel" like it's coming on sooner...........but really it's just the difference in the drive ratio.
