Good resource. The theories of tuning described apply to all carburetors. What it all boils down to is "How's it feel." Lambda sensors and dynos and plug reading can get one in the ball park, but nothing beats a sensitive butt for the ultimate tune.

Not sure if it is posted anywhere as yet but I found a tune up manual from Mikuni carburetor here:

Thanks that you've sharing, what you've found on my server.
One of my customers has found this file somewhere in the internet and sent it to me. This manual was very often a huge help for me.

This manual and a Koso air/fuel meter are the perfect tools to adjust a carb.
Air fuel/ratio

I am using this mini A/F ratio meter:

Thanks, Peter. YEARS ago, when I was a Suzuki Service Tech, I attended a week long course on carburetors and tuning. LATER, multiple courses (with GM) on carburetion, fuel injection, tuning and driveability. I'll be rejetting my new TW pretty soon. Should be fun. :)
