I happen to live near there and went over and met ivan. I have a power commander, 2 bros pipes, k&n air filter, and never run super unleaded. I havent had any of the problems with sputtering and spitting, but i noticed the bike runs best at 4500rpms, and most effeciently at 3500rpms. Anyway , I put this little blue thing on and my bike is "BAD ASS". I got it a month ago and have two brand new speeding tickets now. HAHA. I feel like I'm on a GSXR dirt bike. lol. I got scared at 140 (registered on speedometer) and backed off but she had plenty more left. The bike was pretty stable too. The only thing is the green sixth gear light doesnt work (who cares). I really like the way it accelerates and you have better throttle control. I dont really know what the tre is but it works great! Ivan said the only thing different between the dl1000 engine and the tl1000 is the cam, so that explains the acceleration and speed of this bike. Between the dyno power commander, and this tre my bike is so torque'yand powerful i have to remind myself the front wheel belongs on the ground. by the way, my radar went off and i was clocked at 117 if 5th gear while i was hard on the brakes. The other time i was in third (w/o radar detector) when he clocked me at 85. I didnt see him until later when two other cops had formed a road block. It took 30 minutes for me to convince the law that i wasnt running. After looking at the bike and my record (which was good), they finally decided i was telling the truth and let me go with a speeding ticket.
