- Nov 2, 1999
I just changed from a 1999 cr 250 to a 2004 yz 250. Are there any "yamaquirks" I should know about. I was well satisfied with the Honda I just like change. My yz has already fouled two plugs, then I leaned her out and that took care of that. Ive already disassembled the bike and greased everything. Ive put a skid plate, frame guards, radiator braces, 11 oz flywheel weight and scotts stering stabilizer. Ive only made two trips around the yard on the bike. Each time I foulded a plug. Anyway I plan on breaking the bike in proper fashion soon on the trail....Any experiences youve had with the 04 yz 250 i would be glad to hear them good or bad. Ive also been hearing that HP2 2 stroke oil is notorious for fouling plugs. Ive had the maxima and silcolene oil recommended to me as a better oil. Any thoughts on this would also be appreciated.
