WHAT SHOULD HTE GAP BE FOR A MONSTER S4 FOR HTE SPARK PLUG

 

[Guest]

i think i set my plugs at .25 inch or .635 metric

 

[Guest]

thanks. I tell you what, I just pulled my plugs, they were like gapped at .35 " !!! Had the 6K service done at Munroe in SF. Kinda pisses me off if they did not gap them properly !!

Best to keep between .035 and .040, really. You'll find that every model of NGK ever made comes to same gap. Open box put plug in bike. Don't be mad.

so why is that ? The manual says otherwise

 

[Guest]

the gap is for the champion spark plugs

 

[Guest]

I am just using hte NGK equivalent. I htought that the gap should stay the same since the plug is identical.

so why is that ?

 

[Guest]

thanks Chris !! I always thought you should regapp or check the gap of plugs based on what the spec calls for in the manual. Think I should regapp them to what hte plugs were gapped at ?

Do what your bike tells you it is the happiest with. I think part of the problem with champion are the narrow gaps.

The old standby plug gap has always been about .032" (or the thickness of a match book cover), but if you want to get right down to it, the widest plug gap that your coils will fire will usually yeild the best results. See Chris, I'm trying to sell some of your Dyna coils!!

 

[Guest]

so what happens when you gap them too small ?

HEy Chris, do you make Dynacoils for the S4 ???

Bike can start misfiring... occasionally skipping a firing cycle.

Don't the S4's have the plug cap coils? That's assumed to be superior to conventional coils and plug wires, as there is no transmission lines (spark plug wires).

Right now, Dyna coils are only for carbureted Monsters and SSs. I may come up with something for EFI 2V monsters, as they use same crap coils as carby bikes.
