Hi Folks-
Been a while since I was on the forum. Cars, house maintainence and work get in the way of my bikes sometimes. Revolting concept! Finally went and did it- after 40 years of lusting and 20 years of actively watching I got a Rapide! Wanted a Shadow but I can't justify that for riding out to the blacktop on the sand road then dodging the deer while heading for town. Figured I'd better do it while I have enough leg and hip to start the machine! One thing glared out at me though- when pulling the plugs for a look see and cleaning-- they are iridiums! Of course this varies from what the owner's handbook says but here's a question- Is iridium a good choice? If not, what is the most accepted modern plug choice for a Rapide in good order but not squeaky fresh? The guys at the parts counters here in the middle of Kansas already look at me as if I just fell to Earth when I look for parts for obscure British stuff, cars and bikes but I think the word "Vincent" would have them running to their smartphone for warmth and security. Though it best if I just asked the gurus on here.
Thanks in advance for any opinions on this.

Mike,

I have always used NGKs and never had a problem. B6ES or B7ES on the street and B9ES racing. Never had one fail and I never thought I needed better.

Years ago I think I used the Champion N9Y.

What ignition ? And what iridium ?

.
All thing being not equal
Fine wire plugs can aid an old magneto in cold starts
And general reliability .
Its easier to initiate a flame kernel with a thinner electrode .

Thanks for the replies. All I know is British bikes but am brand new to a Vincent and they are different. Frankly, I'm a bit intimidated by it. Surely that will pass. Ignition wise, I'm running a magneto, freshly rebuilt and timed and the plugs are Denso's. Didn't record the number when I had them out.
Funny example of my ignorance on this bike- After it was started for me by the seller so I could hear it, we finished the deal and he went on. Went out to run it to the blacktop and back and spent 15 minutes looking EVERYWHERE for the key! Du Huh!

Just an update-
Due to the driveway being flooded I haven't had a chance to ride the Vincent since the day I got it. About a couple of months ago. Finally said "Damn the trickle!" (Of water flowing across the driveway) and took it out for a short ride yesterday. 3/4 miles of sand road then a run around the mile section (4 miles) on blacktop then back in on the sand. Starts and runs great! Different world from the Triumphs, Nortons and BSAs that I'm used to! I suppose some of you are clutching your pearls right now but I looked for and bought a Vincent to RIDE. Not to cover in plastic and rub with a diaper once in a while. It's a bitsa but a beauty! Oh, to stay in line with this thread- I put in a new set of NGK's to run on. Old school, yes.

Could you describe a difference compare to the bikes you had ?

Hi Adam-
The Vincent has an altogether different feel to it. It's less buzzy than the Truimphs and the torque comes on differently than the 850 Nortons. It feels more substantial than either one, with less of the feeling that you can flick a butt cheek and change lanes and I feel less inclined to toss it into a corner recklessly.
Could be from being new with them or standing in awe of them for so long. The clutch feel is light and lovely. I'm still in the process of dialing in the brake and shifter positioning. No tach is different and that humongous Shadow speedo is really different. ( Yes, it was added on but I REALLY DIG the looks of it.) Gear spacing is really intuitive and the 1 up 3 down is the same as the Nortons so no issues there. The machine has a totally different set of noises that I'm not used to and the headlight moving up and down when you apply the front brake with some fist to it is something else. Having a 2 into 1 exhaust is different for me, I can't turn my head and hear one side or the other. That's all I could gather from a short 5-1/2 mile run. The rain came again with a vengeance so the driveway is flooded again. Might be some time before I can take it out again. Next up- a Ride To Town!
