All,

I have about 20 hours on my bone stock 2020 KTM 250SX-F and I am having an issue with possible flame outs? Not sure if I am on the right track or wording this correctly, but I have had a few occurrences where I go into the first turn or have to brake hard going into a turn and the bike will shut off. Clutch is pulled in and seems to still have good life. It has happened on the line as well when I shift into gear it will occasionally shut off and can be difficult to start. I have tried 93 Octane, Sunoco CAM2, VP110, T4, and T4/93 mix with basically the same results. Is this something that I should look into mapping my bike differently? Should I change fuels? Looking for some guidance.

Another thing I have noticed is when the bike is first fired up. There is a noticeable tick for a few seconds when the bike first fires up then it goes away. Not sure if this is a common issue but it is slightly concerning.

Thanks in advance.

Check your idle should be around 1900 rpm
cam chain tensioner takes a second to load up with oil pressure

Check the manual for idle speed, i know on the 2018s the idle spec was 2300rpm, had customers that would have flameout issues and when the idle was checked it was lower than 2100.

Raise the idle, remap ecu from Twisted Development. Or Vortex ecu from Twisted.

Had given some thought into getting my stock ECU Remapped, how will it be for a stock bike?
