From  30 years as a shade tree auto tinker, my plugs of choice has been Autolite,and NGKs,, Bosch Super 's work good for me too.I use Champian in my Briggs& Statton engines cause I can't find anything else.
I stopped using Chumpians years ago when I couldn't trust them to work ,new out the the box, maybe the QC/QA is better don't know.  I like Autolite too.

Scooterbob is the Autolite 4063 the way to go in a 500cc iron barrel?

the 4063 has been my choice for about 5 years now.....
price and availability is what sold me, and they work. Mine gets
a new plug at every oil change.

The old 4063 is a good choice - so is the 63 if you want a non-resistor (gasp!) plug .... I'll sure pass the word along to Bill ..... I owe him an email anyway! Hahaha!!

So with the autolite, champion etc for plugs, are there different sizes to them that match up to the NGK plugs? I use the b8es but don't know if the other other makers have similar sizing or what? My little RE is a bit touchy around plugs so anything that would be even a bit helpful IE: get me to at least 150 miles before having to change plugs would be nice. I'm carrying about 4 plugs on me (really TD is the one with the plugs in his sidecar).

  Rode a 150 mile loop yesterday and today with an Autolite 63 throwing the fire..through rain.  Not a problem.  And I also had some pretty steep hills and valeeys to traverse.  Not a problem.  I'm sold.  Will.

Again - This is no magic - just a matter of construction. ALL "name brand" plugs used to be twice fired - but with the advent of new, leaner engines with really good ring sealing characteristics, it wasn't really needed. The exception, of course, being all the old and old school stuff that WE deal with! Hahaha!! Good for you and the "Old number 63's"!  ;D

OK, I have to say I noticed a difference, I bought 4 of the autolite 4063's, 2 NGK's BR8ES and did a test over the last few days.  Autolite makes my bike run better, period.  I picked up 2 autolite 63's but have not tried them yet, they are longer than the 4063 and that made me think, then the thought passed.....

I like them, thanks for all the info!

I've been using the NGK BR8EIX iridium plug since I started my break in and it has worked flawlessly. I tried the stock plug, doesn't like it one bit. Tried the non-resistor plug Ace suggested a while back, ran like crap. I seem to be stuck with my iridium forever.

  I have to check other parts sources..Auto Zone doesn't have or can't get the Iridium.  I believe each of these bikes develops its own personality/temperament.  I can run 63 Autolites, runs good but for some unknown reason loves BP7ES NGK's.  I can't figure out why..but I can't knock either plug.  Will.

I assume the 4063 is the "resistor' version and has screw on/off top terminal??

  I'm running the 63 which is non-resistor.  No problems so far.  Will.

This site even lists the Royal Enfield 500 as a application for the "4063" not too many sites list our bikes.

They also offer a lot of hard to find in the USA plugs like the NGK BP6ET ,my cool weather plug that I use in my 500cc iron engines.
