hi guys this question is aimed at an 01 YZ250 I'm looking at. The dude said the bike fouls out a plug every couple of 1hour rides. Fouling a plug basicly means it's running rich right? All it has is a full length powercore 2 pipe and uni filter and the owner before him jetted high and sold it to him. So I can just swap out for a hotter plug change the pre mix oil to synthetic Dominator 32:1 premium gas from what ever he was using and run it. Or should I do the giant PITA job of taking the carb off and checking the jets when I probably get the bike this weekend? PS running a wot run for a plug chop would be a serious pain cause there would be no front wheel on the ground so just plug chop the old one when I get new ones?
