Hope everyone is well. On my first ride out for a couple of month on my 1990 PX150, warmed up with fresh petrol, on full open throttle it's flattening out and losing power. It's already on a high jet, anything obvious I should be checking?

Could be anything. Maybe try a different exhaust. That's what happens when they start to block.

It's got a brand new standard exhaust on it, will check the jetting today, if it's still flattening out should I try higher or lower main jet first?

Thanks : )
