It's also pretty essential to measure both floats as they are rarely 'straight' until you twist them into shape You probably need to tilt carbs a bit further so adjuster arm is barely touching the damper spring plunger.
If you use 93 octane, bike doesn't run right I'm going to go have a look at the thread on DTT, see what I had to sayĪre you running 87 octane non-ethanol fuel? If you use E10% use 21mm float height. Like I said in the beginning of this thread. I'm guessing that float height is super important with these carbs (but not the same for every carb). when i adjusted to where the RPMs where highest, throttle response was horrible. I couldn't rely on finding the happy place via RPMs, I had to adjust for best throttle response off idle. These CB360 carbs are a nightmare to get running right.I have had similar results. On my other carb'ed bike ('83 R100RT), there is a clear "happy place" within a half turn out where the RPMs peak out.
Not quite sure what to make of it or what the next course of action is, as this is needed to be addressed before synching the carbs. Surprisingly, even with sooty black plugs (indicating that it is a bit too rich), turning the idle mixture screws outward from spec (enrichening idle mix) causes the RPMs to keep going higher and higher without plateauing off. I figured with a higher fuel level in the carb bowls, the idle mixture screw adjustment (with warmed bike) would finally happen, per the instructions in the HSM.
