230-250 is ok good running temp I've found for most engines I've run was around 270 so lean it out a notch

I would think 270 is good if you want to lean it out.
I've had TRX's run like a raped ape at 300..

But, remember, you say it's temping at 250,, but what kind of driving are you doing ?
If your racing, hard on the throttle, lots of RPM's then I'd say 250 is kinda low.
But just running around & bashing, low speeds & a bit of high speeds, then your good to go.

Just my .02 cents..

I'm driving a lot of full throtle half of the time and driving on grass and dirt, still at full throtle the other half......I thought 300 degrees was to high? I'm just trying to find the right balance of HSN and LSN.

thanks for your guys input.

I always heard that 280 is Red Lining it. Sit back and ask yourself, "Is it really worth it"?

I tried and tried with the 3.3.
Mine seemed to like to run hot and rich. I was racing it.
I say was because a 15 min main on Sat. and I have next to no compression left. I temped at 310 after the main. And I was not in a hurry to get that temp reading. So it was probably more like 320+.

It never would hold a good tune for me.

Take my advice (same that was given to me by many)
1.) just run the thing, some like to run hot
2.) get a OS [or other motor]

Don't worry so much about the temp.. just don't fry it. Run it a litle rich.. it will rev up and keep runnng pretty strong rich lean it out too much.. well you will have to get a new mill.

just my 2 cents

Persoanally i've had the 3.3 in my revo. The worst luck, and time with it. time afer time at the lhs setting up one minute and completely different the next. I spent more time tuning the engine than actually having fun. After all that, the front main bearing blew up leaving the engine useless. Tried replacing the bearing and reassembly gave problems. So i bought an OS .18tm ebmods and it holds a great tune. Then I got fed up with the revo and sold it and now I'm selling the engine for anyone that's looking for one.
