I had a similar situation to what you did. My bike is stock with pirelli Supercorsas. First I set my sag front and rear, I think my setting were 36mm front and 33mm rear. To compensate for my new 70 series front tire I raised the rear 5mm and dropped the front 1 mm. So i had a total of 6mm. This made a huge differance in the making the bike balanced. The front and rear really give good feedback. As for compression and rebound, it was set up by a suspension guru at pacific raceway. He made a few click adjustments from the kawasaki stock settings. That also made the bike feel better. Hope this helps.
BTW, i weigh 190lbs with gear
