This is very low, for extremes. I had 13/50 with good results, a bit short for transfers.

Went 13/48 yesterday for testing, stock setup, and it really shows carb faults, as it extends gearbox and I get very slow transition on pipe, and drop rpm when upshifting. I have no issues with 13/50.

Still, husqvarna 449 is faster in rolling start.
I think there is still some power waiting in the carb settings.

Where do you buy your needles?
