Wuts up, just got another 450 (i had an 05 yz that i sold last year) its 2006 and the bike pops like crazy. they told me to put the larger of the mains that comes in the bag. so the biggest one was a 165. well, the main in there now is a 165s ?? so should i put the 165 in place of the 165s? I can't see that fixing the problem.. Can you guys tell me for a stock bike what main, pilot and fuel/air screw turns out to get rid of the popping. thanks.
