I am trying to get my bike running right at the moment and I have checked the jets and im not sure what they are meant to be at, main jet 170, pilot jet 48, fuel screw is 1 1/4 turns out, needle is at second from top and attitude is running about 100 to 500 feet altitude?
What does anyone suggest ?

Why do you think you need to change your jetting

It is spluttering at half throttle really bad but clears up if you holt it flat, just trying to see what everyone else runs to make sure its not my jetting.

Jetting should not need to be changed over time.

If it ever ran well in the past, it's not the jetting, it's just maintenance.
