Asking what plug is best is almost as bad as asking which oil is best. You will get lots of opinions....and since I have yet to see anyone post here here that is a qualified spark plug expert, it will be just opinion.....
So, now that you ask...I run Champion N3's in both of my A65's. Occasionally run Autolite's which seem to work well too. IME, NGK's are nothing but grief for me in an A65. Short life, easily fouled, etc. Though they work great in my Y@m@h@ trials bike. :rolleyes:
I've been running denso iridiums, and have bought some 'halo' plugs to try, but haven't tried them yet because the poor old A65 is all pulled apart for renovations, it was going to get bearings and rings but had a cracked piston, so I'm waiting on some better suited forged ones from MAP. Aparently the halo plugs ignite and burn the mixture faster and more completely and need the timing retarded a bit but give better power and economy? So I'm interested to find out, has anyone tried them? http://cgi.ebay.com.au/HALO-premium-ulti...5QQcmdZViewItem
My A65 runs poorly on NGK plugs for some reason. I tried several heat ranges, but they all acted the same; after a few hundred miles, the bike would start running rough and be harder to start.
Switched to Champion N3 plugs and no more issues. Could be some weird coincidence but I've got no reason to switch back and test the theory, so just sharing the experience and you can draw your own conclusions.

I would agree with Lannis. I tried NGK's, had all sorts of problems, including uncontrollable fouling, on my 70 Lightning and switched to Champion's. They run better, are easier to start the bike with, and they don't foul any more.
Hi Guys, I'm using the NGK B8ES because that was the plug allready installed & it is the equivalent for Champion N 3. Unable to get Champion here so can not compair. Bike runs OK. Last month had one time bad starting & running rough till warmed up but my gaps were far too wide. Normal start first time. (Like to try N 3) Regards to all. Spit 67 Boyer ign. GER can't spell chocolate,just say shiit colour.

Champion N3C's on the Lightening and N4C's on the T-Bolt. I've been running these with a Boyer and stock coild and always fire up first / second kick.
I have to add initially I was a five to ten times kicker, but after a lesson in high speed kicking techniques where one learns to kick at lightening speeds (maybe that's how the ike got its name), now each times a winner.
A Honda CBR1000RR guy asked if he could try to kickstart my T-Bolt. He gave up after five very embarrising attemts. I climbed on and first try the T-Bolt fired into life.
Now the CBR rolled over a few times on it's electric starter before firing up. Interestig huh?
