Howdy folks, I just got my 07 uly back from its 1000 mile service and its still running VERY rich, so rich that i can stall the engine with the throttle when its under 3000 rpm. The exhaust smell strong and the gas mileage is only 32-35mpg.. The Dealer swears everything is adjusted to spec. Ya'll have any ideas to fix this.. | ||

I'm new to Buell and even though I got the manual for it, it doesn't seem to have detailed info on the FI and ECM. Having said that, I'll try and help from a more generic view from my experience with other FI systems. Can you determine if one of the cylinders is running more rich than the other? If everything really is adjusted correctly and the map is correct (there doesn't seem to be a reason to suspect the map in your case), this could point to an injector being bad. Basically it's metering could be off and although it would be metering "correctly" in accordance to the signal from the ECM, it would be dumping in too much fuel. If both cylinders seem to be running equally rich,... I have no idea. I don't know of any sensor in the Buell FI system that would send a feedback signal to the ECM that could cause the richness. It may have such a sensor, I am just not familiar enough with it to know. Has it been running this rich ever since you had the fuel tank vent unclogged? I wonder if this could be related to that issue. | ||

Desmo, I ran into a XB that was rich and exhibited the same syptoms that you are experiencing. The idle was rough if it would idle at all. plugs were very rich. Dealership and local shop found no problem. There was a very small amount of water in the fuel. I would try to pull trouble codes first, check the plugs and then drain the fuel. The manual code procedure is on Badweb: http://www.badweatherbikers.com/buell/messages/142 838/256097.html Also, make sure to check you spark plug wire connections at the plugs and coil. Even if the boot looks secure, the metal terminal might not be connected because the boot sides on the wire. | ||

Yea, Ask the dealer to re-do the tps reset procedure. Or, find a BadWeb member that can do it for you. | ||

Thanks for the ideas. I think i need to find a new dealer. I had to Make them do the TPS reset, even though its listed in the 1000mile check up. No trouble codes were tripped, and the bikes has the latest stock map from Buell. How should i drain the tank? is there a petcock in the frame? also is the gas in both lower sides of the frame or just the side with the fuel pump? I'll pull both spark plugs tonight and see if only 1 piston is rich or if its both ? Thanks again. | ||

Desmo, There is a drain plug on the left side. There is a procedure to relieve the pressure in the pump line but I do not have a manual available right now. Maybe another Badweber could chime in and give us/you the procedure. If I remember correctly you need to disconnect the fuel pump connector and cycle the ignition. I can't remember if we needed to run the engine to relieve the pressure. Teep is correct as well. If the TPS was set incorrectly then the engine will run poorly. I highly recommend purchasing TR's VDSTS Standard (Buell) from American Sport Bike. It is about $200.00 but the software is good and the customer support at American Sportbike is second to none. | ||

I drained the fuel when I installed an aux. fuel tank. In front of the rear fender on the left side, you will see a plate with four corner bolts. In between the bottom two corner bolts is the drain plug. I ran down to reserve level, and loosed the plug slowly. I didn't experience any fuel line pressure as the manual says. (dumb luck, I don't know) Here's what the manual says: 1. Purge the fuel supply line of high pressure gasoline. a. Disconnect the 4-place fuel pump connector. Connector is located inside the left rear portion of the fuel tank/frame. b. With the motorcycle in neutral, start the engine and allow vehicle to run. c. When engine stall, press the starter button for 3 seconds to remove any remaining fuel from fuel line. I think my way is easier. In the north country, we commonly use a can of HEAT to get rid of water in the gas line during the winter. I'd check the spark plug connection to the coil as suggested. When I put a set of magnacor plug wires on, I was amazed how easy the plug wires came off the connection at the coil. Yeah, I agree find another dealer. | ||

If the bike was running ok before the 1000 mile check then the dealer did something wrong. My service manager was arrogant and got huffy when I asked them to set the TPS. When loading the bike the mechanic said they checked the TPS and it was ok which means they didn't reset it. I don't go there anymore!! In your case it sounds like the reason they didn't want to do it is they didn't know how! When they tried to do it they really messed it up. Whatever the case, they did something wrong. When you get your questionnaire from BUELL please fill it out and tell them your dealer problem, maybe with enough complaints Buell will do something about it! Good luck. | ||

I guess being way too rich is much better than being way too poor. | ||

The bike is all better now. I talked to Al at American Sport Bike, he said to bring the bike over and he'd check it out. Not 10 minutes later the bike is running the way it should. No more stumble, no rich smell , and pulls below 3000 rpm. Plus i can give it more than 1/4 throttle below 3000 now with out stalling the engine. Looks like the Dealer had everything all jacked up. Thanks again. Al now i just need to clock the miles so i can get the Openbox/Micron kit YeeHaa!! | ||

What did Al do to fix your bike? I just got a used 06 and it has ALL the same symptoms! |
