I replaced the original plugs in my Saito 450 for a set of OS "F" plugs today. It started up and ran like a champ. Just a little fine-tuning on the high and low, and it's cycleing through the throttle range with no hesitation, plenty of top-end, and a nice idle... what a difference a set of plugs can make!

Now, with that (hopefully) behind me... it's time to get this thing in the air for a few circles! Too bad it started snowing this afternoon.
