A gift from down UNDER!!!! Ok John teach us how this dance is going to be done! The Australian Two step! Sent from my iPhone using Tapatalk

Ok a better question. How do you read the BUE plug? Just like any other plug?

So I sat there and played with the test button testing the surface gap plug. The spark travels around in a circle. I can see how this is a big advantage over the retracted gap. If for some reason part of this plug fouls it will still fire. This is the plug for our final tune. However, wouldn’t...

“Use it as a pilot” do I need to be wearing Kevlar briefs? TF guys and BB throw them away after each run. I can’t afford to do that even with one cylinder. Fortunately the BUE is very reasonably priced. What do you think ? It sounded strong and fired quicker than with the BR10ES. Sent from...

Here is some interesting trivia I have discovered while researching spark plugs used for methanol racing. John says you can stick the surface gap NGK BUE in a bucket of grease and it will still fire. The Kawasaki 500 triple came with surface gap plugs back in the day. Many outboard two stroke...

John I look at it this way. You have gone faster than anybody on a Bultaco so fast you peeled the paint off your taco. “It was still making power” I once put a nylock on a brake stay...that was stupid. Sent from my iPhone using Tapatalk

What was the mistake? Sent from my iPhone using Tapatalk

“I guess you meant .0035” yes and edit Is complete. They say a wise man learns from others and this is why we are going to the NGK BUE surface gap plug in the BULTACO. Our piston to wall in the Taco is .0075” so we are good for Methanol. Sent from my iPhone using Tapatalk

Will the Zeeltronic electronic programable ignition fire the NGK BUE surface gap plug? Sent from my iPhone using Tapatalk

What do you think of this picture (the same piston that had the pre detonation). It melted at the edge. So we have pre detonation on the top center and we melt at the edge. 1000 degrees Egt. Chamber Head was cool. Reluctor was somehow magnetized. Data recorder said the ignition was hiccuping. We...

Sorry I wasn’t clear. This NGK BUE spark plug is a non resistor plug and has a solid terminal on top and caught me of guard when I tried to unscrew it. All of my resistor caps are the screw type for the screw terminal stud. Our Zeeltronic electronic ignition says to run a resistor plug. So do my...

Like this? Sent from my iPhone using Tapatalk

I have a bunch of resistor caps for the terminal stud but none for the solid terminal cap so back to Summit we go. Sent from my iPhone using Tapatalk

Going to try this plug NGK bur9eq for methanol Sent from my iPhone using Tapatalk

“Did you melt a piston recently?” A close friend did but only one of the three pistons but many spark plug electrodes. I have been watching the methanol whoosh bottles on YouTube and feel like I have missed out on something in my childhood. I can picture how unspent methane could ignite in...

Wouldn’t your MSV mass squish velocity have to be higher than the flame propagation speed of Methanol? Sent from my iPhone using Tapatalk

Well I learned what MSV was and the flame propagation speed of Methanol. Lol. I was looking for why we had a cool head reading but melted a piston. So why does Methanol melt a piston at a lower temperature than race fuel? How did we have a cool head reading but 1000 degrees on the EGT? Sent...

Oh...I have been trying to figure out what MSV stood for. It is Mass Squish Velocity! You saw that on Ralf’s print out. I read this yesterday trying to figure out why we melted a piston but still have a cool head. It made my brain spin with questions. Chamber was a 1000 degrees but the head...
