Hi there, i just got a 07 YZ 450f, and i started it up ( at night ) and the pipe was glowing red out almost instantly. I held my hand at the muffler and it seeamed real hot, is that normal? it was also around -5 out, i rode it up and down the street a couple times and it seemed to cool down from the cool air. I was wondering if i had to rejet it or??? let me know ! anything i should get done from stock to make the bike more reliable? thanks
