OK long and short,
having 2 problems with the bike

1st is the bike running great good idle and then it comes up to high idle and then if I shake the bike vigorously the idle drops and sometimes kills the bike.
I've cleaned the carb, replaced all jets, and blow out all Circuit using an air compressor. Along with brough a Chinese carburetor off line and still the same problem. Float adjusted to spec along with fuel screw and pilot screw.

2nd it's difficult to find neutral while the bike is running, only running. I can find neutral all day long if the bike is not running. I have already changed the oil twice,last time using Rotella 15-40 weight look at the clutch plates they all seem to be OK. However could it be the basket fingers????
Please need help
Thanks

 

Oh yeah the bike also dies out while throttle is wide open?
Any thoughts......

 

So looks like I forgot to mention the bike, it's a klx125 2003.
I'm new to the site looking for help.
