ok guru's, this is what is happening, what in your opinion would cause this.

lets start, full clean and rebuild of carbs, 2 sizes over mains, 1 size over pilot, needle raised 1 notch, pilot screws set at 2.5 turns out.

throttle cable lubes and return checked, so no hang up there. all and any advice accepted.

Pods are to be changed with K&N type, drag pipes have 8 inch inserts.

the other side of the coin is, when if finally comes back down, it will drop even further then stop. Then it's even harder to start.
so i am at a loss.

Those cheap pods will be covering a few of the air circuits in the CV style carbs. They are notorious for it and the company that makes such filters must be run by a motorcycle hateing genius.

Mmm love hearing those four cylinders. Also make sure you don't have an air leak in the carb boots. Which causes leanness.

sync the carbs after you change the pods
