Spark plug performance?

[Triple A Arsenal]

I'm still interested

Do you know what the part number for the resistor version of autolite ar3910x and for the short reach version of those plugs as well?[/QUO

I understand you want to soup up your bike and make those performance enhancing upgrades...but this whole spark plug thing isnt necessary...Id say Build your motor up! then worry about the small things that Could make you that extra 1/2 hp....other wise all this & that for a stock motor is a waste of time....IMO

I'm almost done with my motor build. Just need a cam and some head /valve train work and it's balls to the wall.. Other then that it's always good to have reference part numbers knowing is half the battle.

If your spark plug Sparks and lights the mixture on fire then it's probably good enough. A "better" spark plug is not going to light the mixture any better.

All most, I returned my mikuni set up due to poor fitment, I'm waiting for them to send me a new set up carb/manifold, I have every thing els for the motor. Things I need to get small round fuel tank, disk brakes set up front an rear, 6"rear wheel. I picked up 2 invader mini bikes and a cat250x frame and a mitchmatch front end yesterday I found a dude with mini bike everything In San Jose! 1 of the invaders is N O S from Calkart in perfect condition!! Going to be on the air base in alameda rippin around on Saturday October 4th 2015 if you want to join come one come all.

I like the Autolite 3910 in my Honda 5.5...snappier acceleration....

So the stock one is good enough, is that what you are saying? I find this not true. I've been hot roding long enough to know this is not the fact especially with a one cylinder motor. Take a v twin put a crap plug in one jug and a premium plug in the other and take a hot lap pull them and give em a reading, see for your self. Take two of the same plugs gap one to spec it will run perfect and slam the other shut, it still will fire and burn the fuel but it going to run like crap. Test it out and get back to me with your findings....

God bless the USA!
