I have an Orion CRF .12 motor. My issue is that it stutters on the low end. If I initially give it full throttle at the beginning of the power curve, it " stutters " on the low end until it clears out and is normal on the mid / high rpm range. I've tried adjusting the needles and it still does it. Any ideas on what's happening ? Thanks in advance.

hi guys.i know that this is an old thread but i want to make a question!
i am going to replace the crank in my crf.i can find 5.5mm-6mm-6.5mm diameter crank for a good price.does any one know which is better?with the big crank timing that this engine has in mind.
have anyone try 5.5 or 6.5crank?

any help will be appreciated!

no one have an answer??
nano?do you know the answer?
thanks!

With the CRF technology, bigger bore cranks do not give straight results like with standard engines. I would tell you to keep the original crank.

thank you nano!
for one more time you help us!
very nice!
by the way you have a pm.

Hi,

I'm getting the Kyosho X312T version of this engine soon. Will be running 16% nitro fuel and looking at using the no.6 orion glow plugs. What is the head clearence of this engine from factory and what head clearence should I use with 16% nitro fuel? I'm thinking the head clearence to use is 0.1mm?

yes.0.1mm.

Is it me or have the parts supply for the CRF Wasp .12 completely dried up.

Since the wasp .12 is no longer available, can anyone confirm if the Alpha .12 parts will work?

Raman Try bartz parts or barts partz ;)

I bought a cranck not so long time ago.. good service
