Howdy,
I picked up a project bike for the winter. This 81 GS550 has what I believe are Mikuni CV carbs the have a 35 or 36mm port on the butterfly side, but no marking I can find like VM34 or similar. The previous owner ran the bike down to empty before parking it for awhile. Took the carbs off, cleaned them(didn't replace anything). Now I seem to be flooding the cylinders(wet pistons after starting). I was able to get the bike to start after the rebuild, but immediately dies. Say start after a few cranks and dies in a few seconds, put camera down the spark plug holes and the pistons are wet with fuel. Any ideas or adjustments to check? The manual I got says the bike came with Mikuni VM22SS carbs, so I am a bit worried if they are a very different size, etc. Any help would be appreciated!
Mix screw: 2 turns out
Main Jet: 92.5
Pilot Jet: 40
Stock intake/exhaust
5000ft elevation
I'll include a picture of the Carbs when I get a chance
