My bike sat for 2 years when I started it up it wouldn’t idle. I took the jets out and the idle jet was completely clogged. I cleaned everything and put it all back together. When I started it up it smoked quite a bit and ran rough. Coincidentally I removed the petcock vacuum line and it purred like a kitten until it ran out of fuel (10 secs). I repeated the test and it happened the same each time. It seems like it’s dumping too much fuel with the vac line attached. Am I missing something?
