Hi guys. I bought a 2006 450 back in April of this year. I uncorked it with the AIS kit and new throttle stop. Wow, what a big difference. I finally got to put some seat time in last Saturday the 17th. We rode about 155 miles or so. After a few minor adjustments, suspension and tire pressure, I really like this bike. The bike started up on the 1st. push of the button, ran strong all day, had great throttle response and idled perfectly. My question is about restarting the engine when its warm. After riding 20 to 30 minute intervals if I popped the clutch or stopped the engine and went to restart it, it would not start right away. It would take 8-10 pushes of the button to try and get it going again. after she started she ran like a charm. I did remove the hot start lever because a few people told me I didn't need it. Was this the problem? Has anyone experienced any trouble starting a warm engine? Any feedback would be greatly appreciated. Thanks in advance. Rob.
