I just picked up an 07 YZ250 set up for off-road. I'm just going through things figuring out settings and such. He didn't have the manual and I haven't ordered one yet. He had the jetting set up kinda weird if you ask me. It had a 162 main with an 82 pilot with the stock N3EW needle set at 2nd from top and the air screw at 1 turn out. Most of my riding will be starting at 3000ft up to 8000 ft in the summer. What would be a good starting point for jetting? I'm thinking 172m, 45 or 48p, clip at 2nd or 3rd from top, and adjust the screw accordingly. Anyone know the float level specs? Also, how in the hell do you remove a pilot jet with no screwdriver slot? All the one's I've seen are slotted.
