I'm all about finding the performance edge. Especially, with these little cars. They need every little bit and every little bit counts. I've gone through full performance tune up on this 600cc 4stroke air cooled wonder. Ignition timing is perfect. Cam timing dead on. New coil wires, new points, new plugs and wires. I'm now sorting the carburetor for maximum performance, here I was trying to richen up the jetting a tad by spacing the main needle. It runs much better and feels "pretty" good, but not "stellar" however. Untill I install a wide band oxygen sensor to precisely measure air fuel ratio, it's just a guess. My wide band tuned 25 hp. 360cc 2stroke Subaru 360 hits 62 mph in the same span as this untuned 37 hp 600cc 4 stroke OHC Honda 600. I need to make some more tuning test runs, I'm not exactly sure, but there has got to be more "umph" to be found. I'm bound to get it.

I bought a 50Euro narrow band meter to see whats happening in my exhaust.Weld a lambda bung into your pipes ,and fit a lamda probe .Connect it to your meter
Then you can adjust the mixture even better.
When you finished your thing ,take out meter and lambda and use it in your other car

Great Idea ! I actually already have a wideband on my other car. I just need to weld in a bung and hook it up.
