2011 TXC 250 starting problems

Hey guys, I have a 2011 TXC 250 with about 30 hours on it. I am having issues getting it to start while the motor is cold. With a warm motor it starts no problem. The bike easily bump starts with a cold motor when I tow it down the street. I shimmed the intake valves (They easiest valve adjustment ever!) which were both .05mm tight. I am still however having the same starting problems. Does anyone have any other ideas?

I would say with 99% certainty that it is the temp sensor, those have been known to go out and cause that issue. I think you can unplug it and see if it starts better.

It is a cheap and easy to fix, but has happened way too often.

Later,

Can you educate me on the temp sensor? Where is it and how can I change it? I have a practice bike I can take parts from to see if it works.

Here is a screen shot from the manual, it is item #27 on the right hand side of the bike behind the cam chain tensioner.



Later,

the temp sensor is on the back of the cylinder.dan

Thanks guys. Ill give it a shot.

That was it! Took the part off the other bike and it works like a charm. Thanks for the diagnosis. MotoXotica had it in stock as usual! $10 fix. Thanks!

Glad that was the fix. That is an excellent bike when it's running right!
