EFI flame outs

Recommended Posts

Has anyone tried to simply close the gap on the plug to about .024" to see if that would cure the flame out issue? At lower RPM, I can see there maybe not being enough energy at the coil to fire a semi rich mix with that silly assed ice cold plug they spec'd.

 

.030-.040' on a 9 level heat range, with a precious metal tip seems colder than necessary, by at least one heat range. Honda has never been known for a decent ignition coil...

Good point, good question. I wondered that myself - also wondering why a hotter plug is not offered. (Yet?)

I will check into it. My 13 just started acting a little strange at the races today. At low idle it hick-upped and died several times. It has been re-mapped a little richer. Runs awesome on the gas just seems to flame out when I come to a stop at idle.

wonder if any of these are a solution?

Kinda unreasonably priced IMO, and i believe i read that the tubular coils are not the hot ticket unless they are meant for Coil on plug, which these are too large in diameter to fit the new bikes tiny plug well so it looks like they took a COP coil and added a plug lead defeating the necessity for it to be a tube.

A more reasonably priced alternative?  I saw these for a bout 100$

Looks just like the taki super coil but sold as black ops moto they claim 1.5-2hp which seems a lot high unless the stock coil was just truly garbage. also silly priced...

And there is these real cheap like 30$ or something

 

 

I think id take the dyna kit coil and give it a test.

seems the least gymicy.

The dyna seems reasonable prices IF it works but that black ops looks great minus the price.. IF it works. Wonder what Ron thinks..

Anybody messed with these? And would the older models gain hp's from it? Hmmm

Honda isnt known for great coils. The exact opposite as a matter of fact. The Dyna coils seem to work pretty good on the street bikes. I know up grading the coils on my 1100 made a difference that is tough to even describe. But it takes time for them to degrade, Id think when new, they'd be enough.

 

I think just closing the gap might be enough. Doing so on a plug that isnt fouled intensifies the spark. If the spark plug is being blown out at low RPM, it'll definitely help. Being a true CDI (they dont charge the coil with low voltage and break the circuit to fire it) the lower RPM charge might (should be 100v min) not be enough to fire it. It may fire it when the kicker is being run through (eyeballing the spark) but with the engine running, the EFI and PUMP using up current etc...and the compression...it might be enough to blow the spark out.
