First of all, this is me ---> :yell:
My YZ runs absolutely fantastic. Power is there, power is smooth, never fouls plugs while riding, it's pretty much perfect. But, when it comes to starting it up after a day of riding or so, there in lyes the problem. Bike starts up first kick every time, and I don't even need to use the choke. But usually (sometimes it doesn't), the plugs fouls on start up. After letting it warm up some, when I go to take off, it makes a bogging sound, and the bikes shuts off. Fouled plug. So then I put a new plug in, and she runs perfectly normal :bang: . I always shut the gas off and my plugs look healthy after riding, brownish/tanish color. I run BR8ES plugs and Yamalube 40:1.
What could be the problem here? Is it a jetting issue, even though my plugs look good? I feel it has something to do with either:
A.) Not letting the bike warm up properly, or long enough
B.) The motor gets too much of a rich mixture on start up, causing it to foul.
I've tried adjusting the air screw, leaning it out some, but it doesn't seem to be helping.
What should I do!? I'm so tired of having to change the plug every single time. :bang: :yell:
