07 XB12scg. It's been at the dealer for 7 days now. They finaly got it running. It was fouling plugs. Timing was way off, TPS needed reset. Previous owner must have messed it up. Anyway I'm about to run down and get it when they call back and say it won't run on the side stand. It runs fine unless it's on the stand and then it loads up and dies. They've checked the side stand switch, and the bank angle sensor. Anybody have any ideas? At this point it's been on a trailer or at the dealer longer than I've owned it.

what happens if they lean it without the side stand down? Is it in gear when they test it? Correct me if I'm wrong but weren't there some models that wont run with the side stand down at all?

Maybe the stand sensor is bad?

Not sure if this has the side-stand interrupt or not but if it does, it should die right away by kiling the spark. According to them, what it's doing is loading up and fouling the plugs when it's leaned over. I'm sure they will figure it out, but damn its weird.

So talked to them again. Apparently it does not do it if the side stand is up and the bike leaned over. Gotta be in the side stand switch right??????

That has to be. Those things are funky. They never work right. I'm sure 90% of the people on here have non functional switches

Thats crazy, if it was a carb I would say the float is sticking when leaned over but what would cause that with FI. Unless the throttle cables are out of adjustment and when on the side stand the wheel is turned all the way to the left causing the cables to close the butterfly all the way and flood the motor.

Has to be the stand sensor, if it kills as soon as you let the clutch out. giving it throttle won't kill it, that just seems that way since you let out on the clutch as you give it gas.

There is a side stand sensor?  Is it only on the scg?

All our bikes have these sensors. If you look at the top of your side stand you can see a bolt head that holds the sensor on the stand. It has a small pin that fits into the nonmiving part of the stand and has a simple contact switch that tells the computer if the stand is up or down.

Mine has been disengaged for years. Would shut the bike off at various times for no reason.

I never knew this.  Mine has not worked since I had the bike.  I always start my bike while the kickstands down anyway. Keiser, I won't ask how you know that your bike will run through all five gears with it down.

Wouldn't you want it to start with the kickstand down?? Otherwise you woud have to sit on the bike for 5 to 10 mins for it to warm up properly before you set off.

Mine is the same as everyone else's, it will take off no matter where the sidestand is. Mine runs around 1 min. before I take off, sidestand OR me sitting.  I'm surprised you're not fouling plugs Hoverjocki or has your ecm been remapped?

The side stand interupt is designed to kill the bike if it is running on the sidestand and it is put in gear. This is to prevent you from riding off with the sidestand down and jacking the rear wheel of the ground on the first left hander. The bike should run on the side stand unil any gear is engaged. I've had other bikes wiht this problem and usualy just short the switch to prevent issues. Latest from the dealer is they believe that there is an issue with crimped and or shorted wires to the side stand interrupt, the bank angle sensor and the TPS. This is causing the ECM to go all out of wack when running on the side stand. All sensors test good.

Bypass kick-stand sensor by splicing two wires together. Normally closed switch satisfies ignition

My bet is closing the circuit kills the bike. If it was an open kill, removing the plug would make the bike not run.

Mine has never worked, I thought it was odd that Buell did not put them on their bikes. I guess they do just not very good ones.

More news. They thought they had it, but by the time I got there to pick it up it was acting up again. So me and 2 techs went at it for about an hour. We knew it was a broken wire as it would intermintantly throw a TPS code. Thought it was the TPS harness and replaced that. Turns out it was the harness for the TPS and the wires comming out of the TPS had a micro break in them as well. We finaly got it to the point that we could move the wires and get the CEL to go on and off. Bad news is that they will have to order a TPS so it will be mid week before I'm back on the road. I'm not too impressed with the factory wiring as this bike has 744 miles on it and its the factory routing that appears to have caused the breaks.

I don't know about his model, but didn't they stop putting them on after certain years? My 08 has no sensor, wires, plug or anything else going to the kickstand. it will start and run with it up or down (not that you'd want to forget about it and take off, but it will) unlike every other Jap bike i've owned that had a kill sensor wired to the side stand.

Resolution. Well here's the final. There were micro breaks in the harness for the tps, the tps wires themselves comming from the sensor, and the main wiring harness that connects everything was being pushed against one of the head bolts by the crank case breather re-route. It put just enough pressure on it along with heat and vibration to open the insulation and ground out on the head bolt. This was between the frame and the head and was very difficult to find and of course was intermitant and worse when hot. Every time the airbox was removed all the pressure came off and the bike ran fine. Very hard to diagnose. Now everything is re-routed shrink wrapped and covered in plastic conduit. Back on the road after almost 3 weeks. That's almost 1/4 of the riding season in my neck of the woods. Put my pazzo levers on and had a great afternoon of riding.

I have had a bunch of remaps done over the year. When i first got my bike it had the stock ECM then got the race chip then cloned the race to the stock chip and then did all the remaps to the clone. Either way the bike has always started with the stand down regardless of which map. This time of year in Vegas the temps are now 105 so it starts a little rough on the second start if still warm sometimes.

Glad it's resolved finally. Too bad it took so long. But being a CNC machine tech I can sympathize with the Buell tech, intermittant probs can be a real mother to track down.

I've got to hand it to the tech Chris at WP HD in EP, MN (enough initals for ya?). Chris took the time to bring me back to the bench twice, to make sure I understood the process he was going through to try and diagnose the problem,got me involved, and walked me through the entire process and resoloution. I like knowing what was wrong and how it was fixed so I really appreciate this. A very frustrating experience for both of us but it got resolved. The best part is, I love this bike. I've owend alot of motorcycles over the years but this was the first one that I thew a leg over and thought YEAH this is what I'm looking for. At 5'5 the scg fits me perfectly. Small light package with a big torquey motor. Gotta go for a ride now.
