Thanks again for that info. My thought process has been wrong when it comes to plugs thanks for clarifying. If only there was that one magical plug life would be easier. Not sure I'll get to burn some nitro today we're getting rain.

Second in regards to your question about humidity, yes it throws everything off as far as tune is concerned! High humidity conditions especially when combined with high ambient temperatures make proper tuning of the engine very difficult. In high humidity type conditions when the incoming mixture is compressed (during the compression stroke) the moisture trapped in the air will attempt to extinguish the glow plug element. This is why you often see people having so called "ghost flamouts" in those conditions, where the engien seems to be running fine and then somewhere on the track it just randomly cuts out seeimingly for no reason.

So the higher the humidity, the hotter the glow plug you should be running. This is why we came out with the super hot #4 plug, for NC, SC, LA, FL etc. in 90F+ conditions with high humidity. From my experience racing in those conditions it is also not uncommon to have to run the engine considerably hotter (so leaner) than normal in orde to get them to run properly. I remember being at a race at the Farm II in high temp/high humidity conditions where we had to run our engines at 280F just to get them to run properly. As a comparison we would normally be in the 220-240f range but at the higher temp they worked properly, showed good smoke and did not run on, so as the saying goes "they run where they run".

Super high humidity conditions and tuning is not the easiest thing to do but I would certainly advise you to change plugs to a #5 if not a #4 if you have access to those. Then if you have to run a larger air gap or leaner than normal (the larger air gap also effectively does that for the LS needle) do not be concerned about it. Just pay attention to how your engine runs and if it seems to be opperating normal then you should be ok. Hope that helps!

This weekend the idle was sensitive on Saturday but a front went through and Sunday was mid 80's and lower humidity and idled like its old self. Running the #5 plug now but will definitely get the #4 before the next race.

Got it Monday. Ran a quart of Bones Brew Break-in Fuel thru it on Tuesday, heat cycling between 200-240*. Then ran 3 more tanks of 30% race fuel thru it on Wednesday just to get the tune somewhat close. Thursday we packed up and headed to Myrtle Beach, SC for the 15th annual Fall Brawl.
Friday was practice and with 550+ entries, practice was at a premium. Every time we could get out there, we ran. Putting an additional 6 tanks thru it, but not quite stretching her legs on the long straights, she was singing. Tons of power and we needed it. The track had so much traction, cars were lifting the front ends coming out of the corners! Bar style tires with sauce was the hot set-up!
On Saturday, we leaned a little more and she rocketed down the straight even passing some Speeds, Reds and Nova's on the way!
By Sunday, the temps dropped to the mid 40's, but the motor was still very happy with the tune. Still a tad on the rich side, as you could feel a little mechanical pinch on the last 30-40* of the stroke, but that didn't stop here from running 8 minutes easy on a tank.


My daughter ran 3 classes there. She was worried that this new motor would be too much for her. By the end of the first practice session, her worries were over and she was mad at me for not getting this thing sooner


Needless to say, if any of you are thinking about this motor, just stop thinking and do it. This thing is killer. Smooth. Powerful. Efficient. Easy to tune and easy to break in. Its been a couple year since I have broken in a motor. I usually send it off, but was strapped for time.


Thanks Ron and the whole Werks crew for developing such a great product!
