Hi guys. I recently finished my super moto conversion on my 2000 YZ426 and now after installing a WR stator, doing the stator mod, BK mod, FMF jet kit, and no air box lid I now have one more issue with my bike. That is other then the silly chain rub. When I ride on the highway and I'm at a constant speed for a little bit I get this weird bog when I give it gas. Then the bike wants to die and I have to pump the throttle to keep it running. If I pull in the clutch and give it gas it will die unless I pump the throttle. But once I get back to stop light to stop light it goes away. Any one have any idea as to what this could be?
