Hey guys i just bought a yz 250 and im having problems with fouling plugs. It starts first kick idles fine has tons of power but after ive been riding for a while and i stop and let it idle and then try to go again it fouls the plug. Possible right crank seal? I've already tried 2 sizes leaner on the main jet. Had a 175, put a 170 in it. Same thing. As soon as i put a new plug in it starts on the first kick. The fouled plugs are always completely soaked. Another issue is the brakes. Mainly the front brake. Lever has a good feel doesnt feel spongy but it just wont stop the bike. I have to use my whole hand to use it effectively. Im used to a one or two finger front brake like my '12 crf250. Pads look almost new... Tusk typhoon oversize rotor kit?? Yet another issue is the rear shock feels very springy (bouncy) and feels like the whole bike rolls back onto the rear wheel under power. Is that a job for Factory Connection?
