Hi guys, my KTM sx250 ran great at cold temps at the beginning of the year, but now when im flat out it seems to not take its gas, like if it was too rich. I have a bills pipe and vforce valves, but it came out Almost like this stock so jetting should be similar.. I was jetted 160, pis it down to 155, still did it. Tried 150, it's the same. The spark plug tip is perfect, but the threads have a bit of oil/gas on it
But 155-150 sounds ridiculously lean. I'd try a 162-165 just to see what the effect is. You may be mistaking lean for rich.

If there's one tip I can give you it's to never ever ever ever ever ever EVER trust a KTM manual for it's jetting recommandations. As in never.
