03 Bayou 250

Problem is that at mid throttle it starts to break up, and gets a little better at full throttle but still breaking up. Wondering what it could be, is it carborator, ingintor box?? or....????

The Bayou 250 can break up at mid-throttle from dirty air bleed holes in the needle jet holder. But, I would suspect the ignition coil is starting to go.

A weak coil will start to break down under load, then seem to recover at full throttle when the mixture is the richest. I would pull the ignition coil and have it tested.

Thanks, any idea where I can get a diagram? Where is the ignition coil located?
