. New plugs NGK BR9EIX iridium.
Can you keep it running with enricheners off ? Even with really long inlet runner on sons XR120 (with Dell Orto) we only used it to start, flicked off, warmed up before riding by using throttle. Might just be a jetting thing ?Other than that, I'd try non iridium before buying exy plugs (Guzzi content) in different ranges.
80/79 psi? That seems a bit low...no?
Hi ChuckThe aero mill was my dream some years back. I'm glad you were the one to live it. I'd had no chance of getting that mill here in Dk. Thanks for sharing your thrills and lessons learned on this project.CiaoBrian
Ok, we're experimenting here, but I think we can safely say that these plugs are too cold unless you are running at near WOT as the Aero engine was designed.
What plugs are those? They look almost as cold as a set of Champion L55Gs I tried briefly in my '72 H2.
I remember talking to a tech rep when we were raceing who said that with modern pump gas additives when the insulator gets soaked, the plug is junk for high performance applications because it will cause weak spark and possibly a misfire. Cleaning the plug is of little use as you cannot get the insulater to release whatever chemical has penetrated it and it won't burn off like it did with the old generation of fuels. That's what I remember from late last century.
That is good advise from Jim at Rosefarm, I think I'll replace plugs at a shorter interval. I was thinking that maybe you could put little 12 volt heaters on the intake runners. What do you think?
I'm thinking you're overthinking it.
Hiya Brian.. don't be a stranger..
