You may remember that I was going to rejet my carbs on my street bike. I have checked valve clearances and had to change out some shims. I bolted my rejetted carbs on to the bike last night and it wouldn't start. After I used some starting fluid   It ran...sorta.

Here's the setup:

Mix screws three turns out
40 pilots
140 main
2 # 4 washer shims under each needle
Did not touch the floats.
UNI pod filters.

The bike was running before I took everything apart. I'm going to double check the cam timing before I try again but assuming that is OK, what should I adjust next? Should I try adjusting the mix screws? Which way makes it leaner and which way makes it richer. Also, I had some fuel coming out of the overflow. Probably knocked the needle valve askew in the handling process. I'll take the bowls off and check. If these aren't shutting tightly, would that make it difficult to start? All of my racebikes have been purchased with the carbs already jetted so this is my first time making changes myself.

One of the floats overflowing will make it so rich on that 1 cylinder it wont be able to run...too much fuel will drown out the spark...You are still trying it at idle right...Check and make sure the floats are closing and make sure they are right at the float gasket level in both carbs with U tube method on the bike. Plugs...what did they look/smell like. UNI's will get gassy if floats overflow...and may stay gassy through a hot day or 2...That might not make too much diff though at this stage. Mains and needles dont make too much diff at idle so all that counts is float level, air screw and pilots and of course choke. Air screw out in richer...
Cool.
