NGK's all the way for me.
no need for fancy electrodes imo, just a good reliable spark and strong plug.
i have seen those electrodes break off in a pretty short time due to erosion in 2 stroke motocross engines, the bore damage was not nice!
i've never faulted an NGK plug in all the engines i've worked on or lived with, regardless of application, they have had a suitable plug for it.
if you fit anything else and you like them, thats all good, i suspect it is more a personal thing, but seeing as you are already changing other settings to suit the plugs, are you sure it was the right thing to do?
Was thinking along the lines that Golden Lodge designed the 4 ground electrode plugs specifically for this engine. Bosch are the closest quality plug I believe.
Yes I was a bit surprised how thin the electrodes were when taking them out of the box.
But a 2 stroke is a different beast altogether and bit like comparing apples and oranges. (even the NGK thick electrode on our 2 stroke Yamaha scooter shows signs of erosion)
Well I'll give them some time.
52 idles were horrible. (did 2 blocks with these and took them out immediately!)
53 were so much better.
120 km drive back last night and engine was crisper, lots of crackling on the overrun and virtually no flat spots.
Engine ran nice and cool even cruising at 140 km/hr @4000 rpm.
Rad fans came on once during a 1.5 hour drive (only when I was parking when arriving).
Overtaking revving to 5500 - lovely sound with the EMPI's and trumpets. (MSD also on)
Got to check the plugs at the weekend to see how they see how they are after the motorway run.
(3 weeks have passed and my dizzy springs still haven't arrived
Must be the Christmas post jam!!
Need to fix the over advancing problem asap - so frustrating not being able to use WOT under certain road/driving conditions.
