Latest on my CB550F Unipods jetting results. I dropped the main jets to #100 (stock is #98), needle set at 3rd notch which is one richer than stock, air screws at 1.5 turns out, stock #38 low speed jet. I used foam filter oil on the unipods to get them set up as designed. Test ride showed improved throttle response, much more like stock with less of a fluffy, burbly feel. Almost as good as stock with just slight hesitation when you hit the throttle, quite driveable in heavy traffic, idles well. Did a midnight high speed test on highway. Good roll on in 5th gear, pulls well and was able to hit an indicated 110mph which is very good for these little guys. Sort of felt that acceleration improved when throttle was closed a bit from wide open in top gear at high rpm. Also under heavy load, in top gear engine seemed to be detonating or "pinging" just slightly. Looking at the plugs was disheartening. They are NGK DR8ES which is one heat range cooler than stock and were black and sooty. Not wet, sooty as in too rich. Next test will be too drop the needles back to the stock #2 notch to clean up the rich running indication on the plugs. At that point the bike will have back to stock jetting except the main jets will be #100 instead of the stock #98. I will leave in the DR8ES plugs.
