My 250 exc is bogging low revs and when pulling away..
Checked loads of stuff today;
Spark plug: br7eix
Main jet: 165
Pilot jet: 35
Needle position: 3/middle.
Air/fuel screw: 1.75 turns..

Not sure what else to check 馃

What needles ? the jets are lean

up the pilot to 40 and the main to 168
Itll be stronger then
Maybe go to clip 2 if its too much

I wonder if it always bogged or if it just started. If it just started and was fine before I doubt it's the needle...

Only just brought it mate and it's a different needle to standard and the one in the manual suggested for it
