pretty sure I am giving up on my txc310r

So i have had the bike for three months now and after replacing the starter motor, having overheating issues, now having valve noise, and the starter just gone out again. I think it is going to be up for sale. The last hare scramble race we did was 100+* and it puked a little oil out the air box. I am just thinking i don't want to bother with it. anyone else have/had similar issues and just pushed through it?

I don't have any of those issues. The starter motor is small and should not be abused. If your bike is hard to start and takes a lot of cranking over to get it to fire you will burn up starters.
Oil in the airbox can be cause by long periods of high rpm riding or the oil be over filled.

it is highly likely i over filled my oil. the race was a 2 hour flat out race. so that may be it too. I found someone willing to trade a 2011 ktm 150sx and some cash for my bike. I am probably going to take up the offer

My 2010 TE250 was one of the 1st ones in the US.
I had all the starter, valve cap, fuel pump problems ad naseum for the 1st year..
It has run fine for the last 3 years

Apparently those of us that have remained have a higher pain threshold than you. I have been the starter, woodruff key, Flywheel issues. It's a shame because when the bike run's it's great I completely love everything about it except the lack of a wide ratio transmission. Unfortunately it never run's the way I want it to. My starter motor sometimes turn's over and sometimes just gets stuck. These bike's need lots of love! like LOTS and LOTS in order to run like you want them to for long periods of time. Best of luck with the KTM well see the next owner on here soon.

I found the best thing to do about the starter is to use it sparingly to re-lite on trail stalls, which after I've "I-beaten" it to perfection is very rare.

It kick starts easily. 1-2 max.

Once it finally goes away I will remove the E-start entirely!

My starter works fine since day 1 every time whether hot or cold. everything is stock with the starter. I did slightly adj my valves at 500 miles. I also trickle charge my battery 24/7. Maybe a strong battery is the ticket?
