2011 TXC 250 running glitch

Hey Guys, well I have one that I don't seem to find the answer to yet. Hope can get some help. I purchased a used 2011 TXC 250 last year and has been running great until about a month ago, starts fine but when running just off idle (girlfriend riding around lawn) or when going into a corner the bike will cut out or stall. It does restart but will continue to do this. If accelerate hard no problems. Have replaced what I thought may have been a clogged fuel injector and also tested fuel pump, still have the same problem, have heard rumors of the temp sensor but don't seem to have the right symptoms. Any tips will be greatly appreciated.

If it has the original temp sensor change it. They are failure prone.

Also, make sure your TPS is set right...you need I -beat or a dealer to do this.

I-beat will also tell you if the sensor is bad.

purchase the updated ecu and injector kit... it is about only way to get good just over idle throttle response.dan

Thanks for the input guys, I do have the updated ecu and injector and throttle response off idle was great until about a month ago when this started happening. guess have to bring it in to dealer and hook it up to the I beat to be sure.

Hey Jon, did yours always have the stall/bog or did it start doing it after time? Seems like this was all good now has the issue.

I still have the stock ECU and the 4pt injector and while it is no snappy off idle, it starts one kick, and pulls from down low and NEVER pop stalls.

I have adjusted it with I-beat and run an Arrow full Ti exhaust system with SA installed. It is still quiet.

Well, replaced the temp sensor and all is back to normal.
