| Don't worry about going down in the front...you can't. It comes with a 14 and no one makes a 13. Down one in front is equal to up 2 1/2 on the back, so I usually err on the side of acceleration and go three. I went up three on the SS and have no regrets. Gonna do the same on the 749. I wouldn't think up 2 on the 749 would be good enough given the rpm range of that motor. Just me though. |
