I decided to try a new spark plug. In our quest for better performance I see a lot of people going to race coils( Nemesis & Dyna)and better plug wires.But seem to stay with basicly stock plugs.So I started reading and came apon Nology Silver by Brisk.After checking out their web site I decided to spend the extra money($44.00 shipped)this does sound like alot but considering what people are paying for coils&wires still alot less.
here`s the basic run down(Silver center electro(no resister),increased HP,
long lasting,top quality materials,cleaner combustion.race proven design.
way higher thermal and electrical conductivity than Platium or Iridium.
I know what your thinking,no resistor RFI ,didn`t happen.What did happen was this,excellent idle,great thottle responce,reached RPM limiter much sooner,took here up to 110MPH than ran outa room.There site explanes things much better than I can www.nology.com.
My current settings.Dyno jet needle 3rd clip stock spacer settings,
Mikuni 170 main,stock 35 pilot,PMS at 2,Thunder Mfg.tear drop AC.
Road House Doolies,stock coils & wires.My MPG already seems better but only did 70 miles today will update you when I get a long ride in.
(was kinda hard not gitn on it today)

If you never try something new you`ll never know.
