Last fall on my last ride my bike started to stall at stops. It has about 20,000 miles on it and has been serviced by dealer when it was scheduled. I heard someone say that there is a problem with fuel pump needing an o-ring. Talked to a local dealer in illinois and their service dept said that they had not heard of such problems.

 

My buddies '08 SG does the exact same thing. Never know when it's gonna happen, but I can hear the swearing when it does! I know they've replaced the throttle cable cable, but it didn't do anything. Then they replaced some of the hoses and o-rings in the fuel injection, still no help.

 

my 07 SG does the same thing after about a 20 min. ride. Sluggish IF I can keep it running! Jamie at fuel motto said the ck the %...will keep you posted.

 

In most cases the Idle Air Control metering needle is gummed up in the inlet of the throttle bore. There is supposed to be some throttle bore cleaning solvent on the market. Spray some on the metering needle while cycling the ignition on/off a couple of times. The oil vapors going back into the intake can gum this thing up. Worth a shot, pretty cheap too. Looking in the throttle bore it's in the upper left section (11 0'clock) of the bore.

 

Any diagnostic codes?

 

I seem to remember reading a post a few months back,(last fall), referring to a hole in the fuel line causing this. This has happened to me on a few occasions as well. If I kill the bike then fire it right up, it idles just fine however. I have not had this occur yet this season, but if it continues I may have someone look at it.

Cheers,

Tom

 

There was a problem with the plastic fuel pump/filter housing located in the gas tank on some models. My 08 had the problem. The plastic ears that held the pump or filter locked in (one or the other, can't remember which) would break causing a loss of fuel pressure. This caused the bike to stall out a lot. Dealer came and picked the bike up and repaired it free of charge. There was a recall on it. Don't know if this affected 07's or not. Only way to know is have your bike checked out. Lots of things could cause your problem.

 

Is there a schrader valve, looks like a valve stem fitting on a fuel line? It is for monitoring fuel pressure. If so you could put a fuel injection pressure gauge on it, tape it to the bike. Then try and recreate the problem, then look at pressure, if it is dropped off, you found it.

 

Pull in the clutch when you come to a stop, that should stop that pesky stalling issue.
