I have a 97 tour classic. I've cleaned the carbs RELIGIOUSLY. Four times now. I have the bike running, but when it idles, gas pours from the overflow tube. At high RPMs, it stops leaking. I was able to seemingly relieve it for a time as it didn't leak, but it's back now. I tried a seafoam soak for 48 hours, no progress. I'm planning on taking them apart and cleaning them really well again. All jets have been clear, float needle moves freely. Am I looking for an o ring or a seal? Diaphragms look brand new and needles seem to move freely. I'm just gonna clean it all again, piece by piece and see what happens, but if you can tell me what to keep and eye out for, I'd really appreciate it. Thanks!
