Your face is red. Next time you are outdoors use sunscreen. 😜

"She"? 😆

They are not "voodoo". There work in logical, explainable way. The difference between those two above will be at very high throttle openings/high rpm. The one on right will get on main jet sooner. I'd say slide shape, location and size of holes in slides are way more on "voodoo" spectrum. 😁

Healthy. 120/75. 56 bpm resting.

Well, I predict 5 pages. 😁

Can you hook up multimeter to the motor, and drive around to see if it is powered when goes kaput? And if it doesn't get juice just work backwards of current path.

Yea, I was just gonna post it. Give it all good fashion whack.

Size of main jets has negligible effect on mpg unless you go WOT all the time. If bike pulls great at high loads, and you wanna improve mpg, attack pilot jet size and needle position, but leave mains where they are. I mean carburator like in xx has overlapping circuits that come into play at certain loads and rpm. Size on main jets is the most important in 80-100 percent of the load, but gradually goes to zero at idle and near idle speeds and loads.

I need head strap to prevent my head from blowing up.

I need head steering damper.

What is the theory behind different mains, wouldn't outside cylinders run little cooler? Different length velocity stocks?

I could, probably, fix it in one Saturday. Except I'm way back on my projects as is, and, 1000+ miles away 😁 Probably 1000 bucks for parts, like 100 bucks for seals and bushings, brake pads, front rotor could probably be salvaged with elbow grease, chain+sprockets like 250, send rear shocks for rebuild. There is always more in parts vs. casual estimate,,,,,but 1000 would, probobly, do it.

Also, if diameter is about the same at the top, shorter will richen mixture at heavy loads, might not be a bad thing.

What about diameter at the top, thick part of the needle? Same? The difference at the other end might not matter much, it comes into play when you are between 60-90 percent of the load. 100 percent is all about main jet. Also, does longer needle is still in tube when slides are fully open? Last question, is that strictly needle replacement, or you are installing full jet kit, different jets, etc? If answer is yes those needles are designed to work with jet kit, they should be OK.

Classic Zero. No need to elaborate.
