The 5.75 is way too lean for a 125. Even the 5.0 is almost a little too lean for the 125 and you have to make sure the rest of the jetting is proper to make the 5.0 work. If you want a simple answer to the needle dilemma and just address that directly, the 43-71 has grooves cut half-clip richer than 42-71. So, the 43-71 on clip-1 is essentially the same as 42-71 on clip-1.5. Basically splitting the difference that you're having the issue with.

I figured that out regarding the variables, but I'm kind of lost with my troubleshooting roadmap. The clip adjustment with the 42-71 needle acts like a 1 or 0. Clip 2 stutters and Clip 1 bogs. It feels like the range between them is nonexistent. I thought a leaner slide could introduce more "range" to adjustments, the stock slide being...

What would you suggest for my -22 KTM 125 SX? Sea level. Temps below 20 degrees Celsius. Carb is the stock Mikuni TMX 38. - Should I keep the 32:1 premix or change it? - Should I keep the Castrol A747 / go with full synthetic / or does it matter? - Should I change the stock slide to the...
