Don't know if you changed your oil recently, or changed brands of oil, but oil plays a big part in the smoothness of shifting. I'm on my 4th brand, and have finally found one I'm happy with. Tried Rotella T, then Rotella T6 Synthetic, then Mobil 1 20W50 Synthetic Motorcycle, and am now with Valvoline 10W40 Synthetic Motorcycle. I've been looking for a synthetic that will shift well, and the Valvoline so far, is doing really well. Will probably try the Mobil 1 10W40 Synthetic Motorcycle next, since I'm partial to Mobil, just to see if it might be better than the Valvoline. Anyway, just thought I'd mention the oil as a possible shifter problem. I know it has played a big part in my shifter smoothness and accuracy. I also have the shifter pivot, that works great regarding steadiness of the shift mechanism.
These are the times that try men's souls. The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of their country; but he that stands by it now, deserves the love and thanks of man and woman. Tyranny, like hell, is not easily conquered; yet we have this consolation with us, that the harder the conflict, the more glorious the triumph.
Thomas Paine December, 1776
