i ordered one of these in the shop to check out. Looks really good as it is the tuned version, ceramic bearing, Crf crank. I will check the timing #'s in the next couple days. The plan is to modify it. I did find some aluminum shavings on the piston so it is a good idea to clean these up before running.

Hi Rex,

Could you kindly share your method of cleaning a new Nitro engine to rid metal shavings ect..?

Thanks

The best method is to rinse out the block with fuel.

Rex

Thanks for the pics Rex. Was thinking this is my next engine. Will wait to hear what you have to say about em first.

Thanks Rex, I tired to pull apart a New engine and it was impossible to get the Rod out...so I pulled the carb off and poured fuel down carb throat (back plate was off).

Is it picco based or Lm ?

Lm based same as the Orion's the last few years.

Rex

Got the engine from Rex and ready to break it in...gonna do some tanks on the bench hopefully this weekend. Engine looks nice, Orion quality. Will see what this engine can do in the 4.0T....Thanks Rex

Is this still under the Orion brand or is the whole CRF technology sold to someone different? I remember the CRF was placed under the nVision brand which was a a brandname from Orion.

that I'm not sure about. I do know the Nvision CRF was a little different from the Orion CRF tho.

Finally had a chance to break it in on the weekend after Rex did some tweaking. Very easy to tune so far. Break in went smoothly with no hiccups and will put a race tune on it this weekend and give it a try as soon as our track re opens in a couple weeks.

i did some testing with it, very smooth and excellent top end.

I just picked one up. Will tare it down and flush it tomorrow.

What plugs u guys using in this

I'm using a werks #6
