I haven't ridden my IT much, just around the neighborhood a couple times and out on the main road to wind it out. Good feel to it. It moves out better than my street bike, but I dearly wish it was electric start. Glad to hear they're good bikes, I took a shot in the dark on this one.
Give Mobil 1 a try. Fully synthetic, I run it at 32:1 in all my 2 stroke stuff. No smoke, no spooge, no fouled plugs, very clean burn. No two stroke funk that sticks to your clothes and hair. If you're curious enough, a search here on AS for "mx2t" will bring up lots of info. Most Autozone's carry Mobil Racing 2T(same stuff, diff name) by the quart. My IT loves it.
