84Gpz750, stock carbs, stock everything. Pulled the carbs to clean them, pulled mains/pilots/needles/and cleaned them out. I did not pull the floats or the float needles.
What I was having was a problem with the bike starting below about 40 degrees outside temp. Was shown a trick: put a rag in the airbox and it will start every time, but you have to get the rag out quick!
Happened after a professional cleaning last year and my refreshing this year still. When I activate the choke with the carbs off the butterflies look closed as well as they can. Plugs are clean, more black than tan, but clean. Compression was good last time I checked it, and I have redone the head gasket and the valve seals during this time. Coils and plugs have been changed too, along with a CDI problem that I am working on when I get it to start.
Who's got a few minutes to explain what I don't get here? I would like to know my next step when i pull the carbs off again, see what I missed/need to look at.
Thanks guys.
