2016 Ktm 250sxf, sounds like a flat battery….. but it’s not!

I deal with the difficulty so you don’t have to. If your bikes gives of any of these symptoms and you can’t work it out, it might just be the “starter torque limiter gear”
sounds like a flat battery but you have a new / charged battery
backfiring into the intake
hard to crank over
sounds like valves need adjustment but they are in spec
will turn over fine with the idle speed wound down
can roll start and runs fine but still want start even when warm
