Hi I’m dylan and I just came across a 2001 400ex with a few problems. Here’s what I need help with the bike starts right up no problem but won’t idle. I get it going and I get into about 2nd gear and as soon as I let off the gas it goes to sputtering then it dies out. But cramps up right after could someone please help!!!! Thanks

2nd. Pilot jet clogged
3rd. Mixture screw clogged or set wrong
