You dont need to rejet, if you havent already, adjust your pilot screws to 2.5 turns out from closed down as a starting point and tweak from there for best throttle responce.

I have a wider tire on my rear and yes, it dives into turns better.

 

I've got a 140/70 (Bridgestone BT 45 Sport/touring) on my rear and I love it. Looks and rides much better. I asked my local Kawi dealer about going to a 150, but they said it wouldn't clear the arm towards the front. I think it might, but I sure won't take the chance.

 

I have a second gen andrun a150/60/17 on the back and it fits fine.
