2000 RC51 Flooded

Hello All,

I recently purchased a used 2000 RC51. The bike did not run when I purchased it but, was said to have run weeks before. The fuel pump tested bad so, I replaced with one from Fuel Pump Factory. After replacement, the bike ran and idled well as I ran it up to full operating temp and then changed the oil as all the fairings were off. The oil smelled of old rancid fuel. After a few days,(busy) I was finally able to take it for a ride. Within a few miles the bike was acting like it was getting way to much fuel. After staling multiple times, I limped the bike back home. Not knowing what to think I had bounced the idea around that I had removed the Power Commander that was installed on the bike during the new fuel pump install. I decided to put it back in. After reinstalling the Power Commander, The bike fired right up and ran well. The next day I was able to put about 20 miles on. Then, after making a few stops the bike is running like its getting way to much fuel again. I limped it back home again. I removed the lid for the air box and opened up the butterflies. A pool of fuel is sitting on the front intake valves. After removing the air box completely, and hooking up the fuel tank then turning the ignition on, the fuel is leaking into the throttle bodies from the vacuum tubes coming from the pressure regulator. Not much fuel is going into the rear cylinder but, the front one is flooding. Is their a way to test the fuel pump regulator? Has anyone come across a similar issue?

Its my first RC51 and am happy to finally own one. Its not a show piece but, thats okay with me. I did purchase the service manual for it.

just replace the regulator. it's a very common point of failure and takes literally 5 mins to replace.

you just did test the regulator, if fuel is coming out the vacuum lines it's failed.

Hello,

Thank you Wibbly and RC-Devil. I installed the new fuel pressure regulator and was able to take it for a ride this weekend. The bike runs great and is a blast to ride.

Thank You RC51 forum,
