I'll stop there since you said you've done the standard mods. I'm assuming you live and ride in the lower AZ desert areas.

He probably has a boyesen cover, not a free mod.
What is the accelerator pump cover Dan ? is it a free mod ?
accelerator pump is on the bottom of the carby, take your fuel bowl off and you will see it. it is only small, it injects a fuel squirt when you turn the throttle. boyesen cover justs puts fuel in it quicker, and eliminates any quick throttle bog that you cant solve through jetting changes.
