Does having fuel injection eliminate the need to do these things? I'm so pissed off. I missed the opportunity to buy a 2009 XT250 with only 333 miles on it for $2,900.00 the deal of the year, because when I did my searches on Craigslist I typed in XT250 instead of XT 250 with a space so this particular ad never came up in my searches, and the bike sold today. Oh well live and learn. Another good deal will come up eventually.
