The details:

CB550K engine, 4-1 header and exhaust, Stock 550K carbs w/ velocity stacks, Mike R stage 2 ported head, Accel coils and wires, iridium plugs

Looking for suggestions as to what main jets to use for street riding and touring on this engine.

The 550's had a number of different carb setups over the years.

What year do you have?
