Yamaha dirt bike, bog in the mid to high range
I have a '01 WR250F and the last couple times that I have had it out it is real blubbery at mid range up to blast off. I think the main jet could have something stuck in it, maybe, because when you twist the throttle wide open it bogs for a bit then launches on you. Kind of blubbers when you lug it a little too. I'll pull the bowl off this coming weekend and take a look. I changed the plug about 6 weeks back and it was fouled enough that the spark wasn't going to the tip, just sideways, not enough to start the motor all summer.
