Rode the new-on-the-road K8 sevenfifty.... did a 2 mile 1/3 throttle ( steady ) plugchop = LEAN.
Double checked lean stuff, like carb rubbers, all good. Opened #4 to check the mains =110 stock. Bike has stock airbox but unknown 4-into-1 ( think it's a Mac
, nothing exotic )....
The bottom line is ; petcock leaks, carb 2 and 4 leak intermittently too soooo, not upping the mains until petcock repaired and carb overflow fixed, why ?...... carb leak will straightaway cause low fuel levels in all 4 carbs= lean and crappy running
Did open the idle/low pilot screws from 11/2 to 2 turns . Will try that for more low speed fuel tomorrow...
