Please go carefull putting them back in when warm, its so bloody easy to strip the threads on the head unless its stone cold and that will be a complete nightmare to sort!

Cut a bit of hose pipe and place the spark plugs in it and screw them well in by hand before you tighten them with a socket. They'll slip in the hose, rather than cross-thread, then.

Isn't there a trick you can do by cranking on full throttle for flooding? Or am I thinking of a different bike...

I think it's full throttle, no choke, crank for 5 seconds.

Wait 30 seconds.

Try a normal start.

Let someone confirm first...

That works on most bikes, including those with a kick start, but I don't wait quite so long.
Set kill switch to stop.

Not so good if a 2 stroke with oil pump, [squirts more oil into bore] or if carbs fitted with accelerator pump [squirts neat fuel into bore]

Full Throttle also works on my Mille - the story...apparently....is that the ECU does not fire fuel at 100% throttle if there is no normal running. So, once flooded, it will breather air through the motor, removing the excess fuel and getting it into something like a burnable ratio...and then - BOOOM..you shag the sprag clutch and it explodes into life!


I suspect the carbs will still deliver some fuel on an NC and so I'd not bother.

well.... so i went into the garage to remove the plugs so i can clean with wire brush and torch them.... and one of them snapped into two pieces while removing it..... what the fuck? these were pretty much brand new plugs, not even got 500 miles on them. i did not tighten them extremely tight either.... just hand tight and a little nip with the wrench.

am i the unluckiest person in the world or what?


PS Ricky, looks like your only getting 3 plugs to test mate :whistle:

Get some nice Denso Iridium ones instead of NGKs. I've never, ever had starting issues with Densos. As to how the hell you break a plug like that when the insulator shouldn't even take a load is beyond me!
