Alright I bought my new 2000 bird from the Superman guy a couple months back. After riding OK for a couple of days the bike Hydrolocked on me. I opened the bike up pulled the injectors. Had them sent out to be sonic cleaned and flow tested. According to the test data they seemed to be pretty good. I changed the plugs, two oil changes and pumped as much fuel out of the cylinders as I could. Put the bike back together cranked her up and watched excessive amounts of fuel being pumped out of the exhaust seal between the mid-pipe and the can. At first I thought it was just the gas I couldn't get out of the exhaust. But after about 5 gallons of fuel and two days later.........it's got to be more. What I'm thinking is This fuel flow issue must have been the original reason why the bike hydrolocked in the first place, seeeing as the injectors came back good. Now with too much fuel being pumped through the fuel rail and into the cylinders, it's just being pushed out of the exhaust valves and through the pipes. My guess is Pressure regulator or maybe Fuel pump(unlikely though). I had a thread about a month ago about the hydrolocked issue. Anyway I got a 2000 bird with about 400 miles on it. I'm now guessing I'm going to have a few issues with any parts that sat in the fuel for that long period. Any help ????? or suggestions would be great. Thanx,
Vic....

Fuel pressure regulator- diagphram is busted. About $50 at the local dealer, perhaps cheaper online. Mine went on my 2002 after I sold it and the new owner was on his way to pick up the bike. It is located under the tank on the right side at the end of the fuel rail.

I can't remember exactly my steps in diagnosing it, but I seem to remember I took off the return line that goes back to tank (think that was the line). Turned key on (not starting the bike) and if I remember correctly there should not be any fuel coming out of that line since there isn't any vacuum. If fuel comes out, the regulator is bad.

Somebody correct me if I am wrong.

Well I just pulled off the vacuum hose to the pressure regulator and gas started coming out of the vacuum nipple and dripping from the vacuum line. I guess its safe to call the pressure regulator F@$&!!!
