Shooter CB550 Progress with Pix - 4 December - PODs (and help needed)

ready for this one!!!!!!!!!blueing pipes can be a result of retarded timing and too RICH a mixture!!!!!! too much unburned fuel beyond the exhaust valve.after 3 seasons racing,I jetted down(leaner) and back to stock on my cb 350,this with hand made exhaust(loud and free flowing) and velocity stacks(billet,,soon for sale!) went back to hotter plugs!!!(B8),,,,,IT NEVER RAN BETTER!!!......run it it first, jet later!!!!!!! good luck on your build!!
