Just changed from a 300 exc (07) to a 2010 250 exc. Someone has said that I should drop the needle in the carb by one notch? Apparently it reduces over run, makes it more economical and will not kill plugs?
Has anyone else done or heard this?
I fitted my Gnarly front pipe and short FMF and thats it. Ive run it at 40:1 as I have with all the other KTMs
Done a few short practices with no noticeable problems and then last week did a straight 2hr enduro practice without any problems / flat spots/ over run / plug problems etc etc. in fact it ran sweet.
