nxr nklr need jetting help on wr250.

Post by Eric J Foster » Fri Aug 27, 2010 7:46 pm

2007 WR250 with the exhaust insert removed, rest of bike is stock. Anyone know where to go with pilot and main? He went up two sizes on both and, to me, the thing is rich. It takes a while to warm up before the bottom end stumble disappears. If run at low throttle and plug is checked, insulator is sooty black, very tip of plug is white. Odd. NO popping on decel, again, acts rich. Anyone done it and know exactly where I need to be? Very surprised by the lack of real information when a search is done on the net. Thanks all, E
