oh, yeah. i forgot to mention my trip to the hobby shop the other day. i got some black RPM arms all the way around, an 86t spur, and a 23t pinion. i was running 28/86 and now 23/86 but i'm really surprised that i can't tell really any difference in top end. but, i can tell my electronics are a tad cooler after every run and my acceleration is a little better cuz now i can do wheelies if on a high enough traction surface. although i probably could do more wheelies if i tightened my slipper all the way, but i would like this spur to last me
