Thanks for the responses. To answer the questions posed, no I havent been away for awhile. Traded the 12 and bought the 15 at the same time so I didnt have to re-acclimate to the bikes. I believe the differences are subtle, but I have noticed a difference. I guess riding the 12 for over a year did get the bike adjusted to my body, but I never noticed any problems when I first started riding. Maybe it will take some time. And yes, my left foot has been hurting for awhile. About a year and a half. It just seems to be hurting a little more since I got the 15. Shift lever, I have a manual, just seems to be hitting a slightly different part of my foot now. I try to adjust my foot but I cant seem to find the sweet spot that I never had to try to find with the 12. Oh well, I still am enjoying the hell out my new Spyder. I will figure it out soon.
