Running from demons in WNY
I also think a 7 heat range is better for the way most Triumphs are ridden.But I have used 8's in some Triumphs and there were no complaints....
I use NGK B8EG in our LSR Triumph.I don't know if the fine wire G plug is the same exact heat range as a S plug...But plug reading said it was the perfect heat range for this 10.5 compression engine running wide open on 107 octane leaded racing fuel.


650 Triumph modified production LSR record holder 133.1 MPH... Twin 650 engine Triumph LSR that goes sorta fast...

Now , a year later, have been seeing a stumbling sputter that was intermittent but now is more pronounced at idle on up.


As it turns out, the sputtering was a sticking float needle in the left hand carb--Mikuni VM30's.

Bad gas or long spells sitting led to a glob of jelley in the float bowl bottom.

Mikuni floats have a dark coating and some of these flakes were floating around.

Quik spritz and cleanout spray brought the bike to smooth running and pulling strongly.

FWIW--HTH

Nice thing about AMAL's is the drain plug.

The accessory toolkit from Sudco has a Mikuni float bowl drain plug wrench also...



The green wrench on the right side of the tool-tray is an original as supplied with the bike-- valve adjusting for setting the clearances.

Fits over the rockerboxes to make easy work ahead.

Got a few more original tools in there. . .

I never worried a great deal about plugs but I just took the bike in for a re-bore and was shamed when the shop pointed out I had old, odd plugs; one was an offering by General Motors.

So I got two new NGK B7ES. Today I took the bike in for it's MOT test. Shamed again, when the examiner said it was running on one cylinder. Sure enough he was right, one of the new plugs had failed totally.

I thought plugs were simple things, what would cause one to fail? Could it be brought back to life (scientific interest only, its going in the bin) ?

That young man was Kenelm Lee Guinness, of the brewing family, and he was, in his own words, "mad about racing". While studying at Cambridge University he had acted as mechanic to his older brother, Sir Algernon Guinness. Upon leaving Cambridge, Kenelm had taken up racing on his own account and found a home for his racing sable in some outbuildings at an old disused inn called The Bald Faced Stag at Putney Lane on the London to Portsmouth road.

Never heard of that brand before but a good story nonetheless.

Doug,
Do you check for the correct gap before you put them in and do you use a socket specifically designed for spark plug installation?
The wrong gap or cracked porcelain will do them in.
If another new plug fails it's symptom of other problems.
