Do you guys gap your plugs or do you just take them out of the pack and stick em into the sled like i do??? Is there any real danger involved?? I have always done this with 4 sleds and never had a prob.
Lately I have been gapping them on the sled. I don't bother on the car or truck though. I don't think there should be any real danger if you don't gap them, but I think you get a cleaner, more efficient burn with them correctly gapped which in some small way is a performance gain....
I'm not formiliar with ECS plugs, but I know ES and EYAs all come with slightly different gaps from the factory. Also, how would that be possible to have one plug pre gapped for several different motors that require different gaps? Granted it won't be enough of a difference to realy notice, but if you go by true specs it will not be spot on for all aplications and not many plugs will come the same from the factory, like belts for sleds....
beginning of this year, i sold my 97mxz583 to a beginner snowmobiler. The new owner called me a month later and claims he went through 10 spark plugs in one weekend! (it never fowled one when i owned it) I agreed to take a look at it. I cleaned and re-synced the carbs for him and it still fowled out a set. I then pulled the plugs out and noticed he was not gapping them!
Most NGK plugs come gapped in the mid 30's (.030-.033) skidoo requires .018 because of their timming.
When I foul a plug I just take it out of the box and screw it in. I dont think there are any problems with doing it. I think the factory that makes the plugs does a good enough job at gapping the plugs.
I wonder what damage to the MPEM could occur by using too large a gap? I've read where they say not to pull your motor over if the kill switch is on and the plug wires aren't grounded. That'll kill a CDI unit pretty quick.
You toast the MPEM, they check your plugs and the gap is wide open say bye bye to the warranty claim.
