My 929 is having what i think may be fueling issues.

The past couple days I have went for a ride the bike will start fuel cutting randomly until it finally cuts off. Sometimes i can cycle the key to start it and sometimes i can cycle the cutoff switch. This past time it started doing it and when it died i could get it started but if I stop giving it throttle it will cut off. i limped it home but i had to give it throttle anytime i stopped or it would die.
I am thinking it may be the fuel pump, but when i cycle the key the pump comes on and sounds strong.

Has anyone had this problem or know what could be causing it? Thanks fo rany help.

Once it starts to cut out it does it at any RPM or throttle application, that's why i suspect its fueling. I pulled the vacuum line off the FPR and it doesn't leak, so that should be good but it could still be bad i guess. I just don't want to buy a pump if its the FPR or maybe injectors.

I noticed that first time, but it sort of eliminates the ECU, the sensors... you'd think. What's the ounce of fuel per key-cycle number? :huh: Visual being the purge out the fuel line in the beaker? Strong flow, or ??? Shop manual page says?

Edit: Looked up the year/etc. 16900-MBG-013 Fuel filter. 50 bucks or go to a dealer and see they match net prices. That, or NAPA a match. 15 year old filter ever been changed?

New development. If i keep the bike under a certain RPM it will run fine. As soon as i get on it too hard it starts running like crap and will cut off if Im not giving it throttle. Once i cycle the key its back to running fine. Does the 929 have 2 sets of injectors or just one?
