Bog question

[sand rocket]

Im having some issues with my jetting. if im rolling in 1st or 2nd gear and pin the throttle it bogs so bad it would die. If i dump the clutch with high revs it fine, but will foul plugs quick. This sound like a rich or lean problem. Carbs are 34 mm taper bored to 36mm mikunis. Current jetting is 290 on the main, can rember the rest, cpi with a dune port.

you definately sound rich on the mains, but i don't know the jetting on the bigger carbs

I talked to the builder of my motor, said that my pilots were way to big. I did turn the air screw all the way in an cleared alot of the bog. What are some of you guys using for pilots in you 34mm mikunis.

whoa, if you're already way too big on the pilots, and turning the airscrew all the way in helped, then you probably have an airleak, or way off on the needle.
