Fuel Issues

After I got the bike running, I parked it for several days.  When I came back to it 4-5 days later to take it for a ride it was hiccuping and backfiring like crazy after starting up.  This included blue flames out the tail pipe.  After some investigation I pulled the oil fill plug and it just reeked  of gas.  Then after some further conferring with the OA people, it was determined that the petcock was probably leaking and causing the bowls to overflow into the cylinders.  I thought that unlikely since when I pulled the tank to do the initial carb clean, it was leaking 1 drop every 10 seconds or so.  But oh how things change.  When I pulled the tank this time, it was a dribble.

Good thing that I picked up a new petcock for the tank.  Here is the stock next to the ELS lightweight manual petcock.

Not only am I saving nearly half a pound from the bike I also have a true shutoff valve compared to the stock vacuum operated always open valve.

I was wanting to clean all the carbs internals at once without mixing them up.  This is the solution that I came up with.

Here is a fry splatter screen

I took it from it’s holder and split it into 4 parts.  Making pouches for each carb, holding the jets and a number of pennies equal to the carb it came from.

I set those in the carb dip for the night.  Everything came out shining and clog free the next day.  I re-assembled the bowls, checked the top diaphragm for tears and put it all back together.  I then went to change the oil and I’m pretty sure that more gas than oil came out.  Once everything was drained I put in a new filter and some cheap 20w50 for a cleaning cycle.  It will get another oil change once the carb situation is sorted out.  It fired up beautifully, and after a little idle adjustment ran fine.  But after a visual OK of the bike I saw it leaking fuel from #2 and had to shut it down.  I now need to figure out why that is happening.  I am suspecting a full carb rebuild is necessary and something I should have done on day one but was being stubborn.

I now have a full o-ring set and fuel bowl o-rings on the way and will do a full re-build when I can.  Then re-sync the carbs after.
