So...I was able to get both new wheels balanced and mounted on the bike by mid-morning. Sun was coming out, so I decided to take the Drifter out for a good test ride. Well, all I can say is WOW!! Quite a noticeable difference in engine power and pull....especially at low end. the difference in torque is significant. Also, it seems that the gearing is different...seems a little higher at the upper end, especially in 5th. Or maybe it's the quieter engine itself. I'll have to check the specs on the 1600 classic.... Anyway, it was worth the effort to me completing this project. I'm looking forward to getting out and really putting some miles on it soon. Also, with the taller and thinner front tire, it feels lighter in the turns, but my speedometer is still off....LOL
