2013 310TXC problem

[fire1998]

Well guys I'm back. Bought a new 13 TXC310 raced it for a year after setting it up perfectly. Sold bike during divorce. I really missed bike!! Only bike who had me not missing TXC is My 2015 YZ250FX. FX is a damn good bike!! Saw TXC on Craigslist last week with same #plates I had on it. Bike has not been used much because bike developed a problem running. I picked it up for 2k and when I sold it had 30 hours on it. Probably has 40 hours total based on the fact it still has tires I sold it with. Anywho...bike will start but will not rev and cuts out. I have not picked it up yet but will on Sunday. So what could it be....Bad injector, black box or???? Bike has suspension revalved for me, FMF exhaust, tall seat, GPI radiators and hoses, Scotts damper and post and much more!! Has mousses front and back so I know guy has not had them changed. Felt like a hero on bike and it's lIke I'm getting an old friend back. I know I can jump on this bike right away and feel great!!
I haven't kept up on parts for this bike. Are parts available? Previous owner had KTM shop adjust valves and check everything out. Valves were good and fuel pump is good. I'm hoping it's just an injector or something easy. I'll change out fluids in fork and shock and riding soon...I hope.

congrats for getting the bike back. Parts are still not too much of a problem for it- good availability.

When you pick up the bike (and then check the basic, obvious stuff: bad gas, rag in the filter, exhaust plug in, loose coil connection, bad plug, etc) a couple of weird things should get a look:

• bad/clogged injector
• coolant temp sensor
• split in fuel filter or hose (or similar reason for low fuel pressure)
• loose battery or other electrical connections (do this first- easiest)
• possibly sheared rotor key... slightly doubtful

I doubt that the ECU has gone bad- but check the connector at least.

let us know what you find.

good luck.

I'm guessing fueling like the pump or filter. How do you know it's not the fuel pump? How long will it idle?

 

[fire1998]

Bike idles forever. KTM Shop tested pump and valves.

Keep us posted I have the same problem on a 2013 TE310R

Back on a Husky! Badass deal, hope you get it sorted quick!

One mo': possible bad TPS

Bet you have bunch of stuff down in the injector.

Mine had green and black plastic pieces in there.

Cleaned injector and ran fine again.

Mine did same thing. Idle fine but hit gas and would cut out and or backfire.

Picked up bike today. Felt like I was reuniting with an old friend!! Bike started right up but has problems I stated earlier. I'll start with coolant sensor first and send injector to ZipTy racing. Hopefully this will solve problems. On another note.....anyone use the JD Jetting fuel controller? It's $200 on Ebay and wondering if it's worth it.

No need to send your injector away.
Most towns should have an injection specialist (for cars)
Same injectors in bikes.
Have them test and clean it.

Uncouple, clean and treat all efi plug connections as any corrosion will affect sensor readings and running.

hey fire1998... what didja find out about the bike?

Old wife and old bike back. Two birds with one stone... ;-)

Hey guys!! Long time away from here. Just thought I'd update you on 310. I replaced the fuel injection at a cost of $600. Bike has never run better. I only use it for trailrides now with my daughter but love it everytime I ride it. I've got 2 other racebikes that I use most of the time. Don't want to wear this bike out. Its first year it was my main race bike and loved it!! Bike only has 44 hours on it! Hope it stays running for another 100 hours!! Here's a pic of bike.

You replaced the fuel injection??

The whole throttle body with an injector, TPS, MAP, et al?

Save your old stuff. Congrats.

 

[fire1998]

Yep...whole assembly. Cured problems.
