Unhappy 1800c stalls if I stop to quick..

2002 1800c 98,000 miles I bought it new in 2001.. The bike stalls if I have to stop quickly, like when someone cut's me off. The fuel filter was changed 5k ago with an OEM filter, it seemed to help but now it's back..... 2002 vtx1800c with an HPP for fuel management. Vance & Hines big shot with stock baffles and a K&N air filter in the stock air box. Thank for your help Gerryvtx18

Check battery connections, vibration loosens them.
Does the ECM wiring have any clip on connections for the HPP??
Clip on splices will cut the wire. Vibration/movement causes it.
2002---check the 2pin connector(Red and Red/White wires) near the starter relay.
See link for details.

Have you changed out your fuel pressure regulator (fpr). I would think at that milage you probably have but thise were a known issue for going bad. Hans and other are a lot more knowlegable than me on this stuff but thought i'd ask. Mine would act like it would stall out when i needed to change mine. Best of luck!

Yes Sir

My 07 X C Model 1800 does the same thing... I just try to not have to make quick stops... Works most of the time... Now restarting after a quick stop she turns over quite some time before she fires up... Absolutely no problem til the next Q S...

Thanks.... I wired the Hpp in dierct... no clips..... I forgot to say that with a full tank of gas I don't have the problem,but at a half a tank i do stall out. I know that there are no baffles in the tank to stop the gas from rushing to front of the tank, but it was fine when it was new.

I Removed my baffle during tank expansion mod and had a slosh and stall issue when fuel became low.
I Installed an external pump to solve problem.

Did not clean tank. Simply removed it to access front coil mount 'common electronics ground'. All wiring (including the connector you referenced from bares site) is good. FPR changed 4/14 (for PM, it had not failed). Hose routing double checked. Will only occur when tank is down about 2 gallons from full. Jim

If a new fuel filter fixed it last time, I would start there...

Hi Everyone....Thanks for your replies .
This winter I pulled the fuel pump and inspected the fuel pickup . I found that it was dirty with some kind of soot on the material that covers the intake. I showed this to few motor head friends and a couple of them told me this is from ETHANOL in gas. Every time the bike seats during the winter this is what happens even with stabilizers. So I cleaned the intake off with gas and tooth brush and had a test run last Sunday and problem is gone.
Thanks Gerry

Hi All ...Thanks for your replies.
This winter I pulled the fuel pump from the tank and found a sooty kind of stuff on the fuel intake. I showed this to few motor heads and a couple of them said it's from ETHANOL. I told them I always use stabilizers , they said they don't work. So I used gas and a tooth brush cleaned the intake and tested it on Sunday , Problem gone.
Zoom in on the pic's and you will see the soot blocking the holes in the material that covers the fuel pickup.
Thanks Gerry.
