I have a VF 1000 FE ´85 and am trying to figure out what the jet sizes for it should be. The bike idles beautifully, but as soon as you apply full throttle under load, it starts gurgling, hunting at around 4500RPM until 7000, and thereafter there´s an improvement, but doesn´t really have magic performance. From the manuals, there are a number of jet sizes indicated, and I cannot figure out which to use and what does the sizes in brackets mean? I live at an altitude of around 2000metres. I disassembled the carbs and jets were 132 front and 112 rear, but the rear valve seats have worn and overheated the valves and seats
