I just put in some Nology Silver's in my bike. The truth is they don't seem any different than my autolites I had, I just don't like using autolites plus I needed 10 bucks more for free shipping. Maybe it starts a little easier, but I just did pipes and jetting with the plugs.
Not to worry traildog , you are asking all the right questions .
Re: plugs ... this can go on for forever but in my opinion the fact that fuel has no lead additives to foul plugs leaves you with a choice of plugs that are good for 100,000 miles or more before wearing . Your best choice is irrideaum and they will last the life of the motor.
