I just picked up a 06 450x and am having issues getting it to start. The bike was setup right from what I could tell. ProCircuit Exhaust, air box mods, R cam, jetting (supposedly), etc. I have yet to check the jetting, but it runs great when it is running. I was amazed that she did 97mph down Morelia Rd, and 107 mph (strong tailwind) down MX3. 14/47 gearing. She kept up with a 650R (15/47 gearing). The first time I rode it, it took a minute to fire up. The second day, I had to pop start it (easy). Once warm, the starter spins fast enough, but it has to spin for awhile to get it lit. The kick starter is about the same. 10-20 kicks. It just barely wants to get going. We messed with the idle screw, up and down with no help. Any ideas? My 650R (stock carb) starts first or second kick in flip flops every time, hot, cold, laid down, whatever. Thanks in advance for any help. Other than this little issue, the bike is great! Also, any jetting suggestions for Baja? My mileage varied between 78 miles and 108 on 3.2 gal IMS.
