derrickcrf250r84
So I was at the track and rode for 2 1/2 hours was riding fine all day then I hit a jump and my bike started to bog as if it was running out of gas sorta so it shocked me and I rode back to my pick up well then it died and I started looking for any loose wires or anything I might have knocked off when I hit the jump (I came down sorta hard over jumped) well got the bike started and it sounded like crap it was boggin kinda sputtering and now I can't even get it started won't start at all I checked spark and it has spark please any help would be much appreciated I'm not sure if it's a timing issue or something to do with fuel?

Clogged fuel filter... or maybe the fuel pump came unplugged in the tank...or the fuel pump is going out.

I've had a lot of troubles with issues like this on my 11 crf 250 full mod bike. Had good spark. Good fuel pressure. But these bikes melt stators. Check TPS I've had one break. Also when my stator was bad the ohms checked out perfectly...it all started when my vortex was keeping it from running but my stock ecu would allow it to run then the stator finally went. Also get a oring kit for fuel pump. You can use a kxf fuel pump for more pressure too. If you wanna test if it's a fuel issue stick a blue shop rag in throttle body with subframe off and let the butterfly hold the rag then kick a few times and see how much fuel is on the rag

I've got a 2012 CRF250 and had a similar thing happen when the bike was relatively new. Went out for timed practice at the start of the day and the bike ran fine. Then tried to go out for my first race and it died after about 30 seconds. After lots of kicking, I managed to start it for a few seconds before it died and that was it for the day. Waste of time and money.

As above, it was the fuel filter. Replaced the teabag filter inside the tank and fitted one of those twin air pre-filter sock things that sit inside the tank and it has run like a champ and hasn't given me another problem since.

I can use a Kxf fuel pump for my crf? Can I get more info cause i did notice it wouldn't spray any fluid out the throttle body and so that made me think fuel pump but it seems like it doesn't pump enough fuel like it should... but after cleaning and blowing out the fuel filter witch I plan on buying on in the next few days I just thought I'd try cleaning it and it starts and runs not sure on how long lol and oring kit?

OEM is best, but there are others available. In Your case the filters are sold as a separate item and that is good as most bike only offer the pump and filter as a complete unit.
Let me suggest that you purchase a fuel tank sock for pre-filtering the fuel that goes into the fuel tank as you would not believe what trash comes out of under ground fuel storage tanks. You want to do everything you can do to keep trash from getting into your fuel system and thus increase the filter, pump and injector life.

yea you probably either knocked a fuel pump wire loose or maybe your fuel pump died.
