So i have a 05 kx250f that i traded a kx125 for an it was a few months back but when i first got it one/two kicks an it would start up an it slowly got hard to start an finally wouldnt so thinking it was just a carb problem i put a jet kit in an it started working again but not the same it ran for about 5 rides an was back to not starting and i didnt touch anything. so the other day i checked the valves an intake was .004 an .004 and exhaust was .009 an .008 and standard is .003 - .010 and .007 - .016 what im trying to get to is ask is it good to be so close to the lowest number. im new to fourstokes an im wanting to get it fixed to sell so i can go back to a two stroke. any help would be nice thanks.
