I'm not sure your still on this board. I need help with jetting.
I'm stuck on a jetting problem. Have VM-28 mikuni carbs on a 1968 Honda CL 305cc
The carbs are fine until wide open throttle. It dies, it either bucks and surges or bogs. Up to 3/4 throttle the bike rips. I went 15 sizes main jet up and down and it really does not matter much.
The plugs are not wet but seem slight black soot. I can stall the bike if I keep the throttle wide open. Again not difference in 15 or so jet sizes.
I did not want to use the stock 50 year old carbs so bought new mikunis. Something seems wrong mechanically with the carb, or something
If you can shed any light would be much appreciated.
