The Mikuni BS32SS carburetor had a 1.3-inch bore size, with a standard idle rpm of 1,150, plus or minus 100 rpm. Windows 7 x64 torrent. The fuel level measured at 0.2 inch, plus or minus 0.02 inch, and the float height measured 0.88 inch, plus or minus 0.04 inches. Pair of Mikuni BS34 Constant Velocity carburetors be properly Jetted for. It just sounded somewhat probable to me, but im new to the tuning.

It is normal to have some climb in idle rpm as the bike warms. After i shut off the enrichener all the way (choke) and the bike is still cool having just run for a couple of minutes, it will idle around 1000rpm.

After it warms up, it will vary from 1200-1400 rpm (give or take)- and there is nothing wrong with that. An idle up around 3000 rpm if everything is adjusted indicates a lean condition from adjustment, air leak or idle circuit passages being dirty. I would turn the idle mixture out to 3.5 turns, make sure there is free play on the throttle cable, good plugs properly gapped, just let it idle to warm, then use the idle air screw to adjust to 1200 rpm. If the idle still climbs too high, then check for air leaks. If there are none, the carbs need cleaning. BTW- the idle air screw should have a spring on it which will prevent it from loosening, If not, get one.

Also, if it is vibrating loose, the idle will get lower.
