    Hopefully someone can answer my questions real quick, I apologize for being tedious.

    I have the bike all pulled apart right now and have gathered thus far that I should colortune first, then synch, and maybe do it all over just to be sure. I would assume I have to block the yics passage for all of this (colortune specifically, manual says block it for carb synch) correct?

    Do I block the yics passage for colortune?

    Valves are adjusted and fuel levels set. It runs just fine but I have never done colortune before

    Blocking the YICS port is ideal, but not necessary. Colortune is easy, just follow the instructions that came with the plug. Do one carb at a time; go lean, then back out slowly until you hit a nice bunsen blue (tiny, tiny bumps of the pilot screw; bump, wait, read the color, bump again if needed). I will assume that you have alredy done a bench synch and did the full Curch of Clean sermon,

    Ended up leaving it blocked for the whole time/synch process. Thanks for the help
