1980 886 international with 5400 hours on it ,, runs great starts perfect but anything over 1700 rpms the motor surges and cuts out below 1700 it runs smooth ,,changed filters and bleed fuel lines air filter etc ,,anyone know where a man might start,just wondering anything i could try or need to look for before getting the pump rebuilt any advice would be apprecaited

Try replacing the fexable fuel line from the fuel filters to the pump. Looks like a Hydraulic line, for some reason a type of cavitation occurs and a constant flow of fuel to the pump is reduced; seen the same circumstance on the 312. It started at 1400 RPM. When changed, purred.
