After just a little bit of work the newer plugs are in and the bike fired right up really easily. For some reason I think the throttle response is a little quicker than usual which was a nice surprise. Don't forget to use just a little bit of anti-seize to make your life easier during the next plug change. I also used a tiny dab of dialectric grease on top of the plug nipple just before I put the caps back on. The grease makes them MUCH easier to get on and off on top of preventing corrosion. I use this stuff on every spark plug I replace no matter what.

Here are the plugs I took out of my Aprilia engine. They LOOK ok and not that worn out but they just wouldn't work. The gap had grown to just over .035" and I'm sure the carbon that had gathered over the 15K miles just was too much for the plugs to operate. I'll be using my spare engine plugs for now but I'll be ordering a new set when I put in another order for motorcycle plugs.
