Yep.

thanks for the help!

Is there any difference internally between the standard 2015 CRF Factory Tuned 3 port (ORI80701) and the RS Edition (ORI80704). They look identical on the spec sheet. I see the supplied venturi is different, is that all?

The crankshaft on the RS is silicon filled and is balanced. .. the other dont

How many ltres can u get out of a 3 port crf .21

I currently have 40 litres on my RS 3 port and it's going strong!

Orion make fantastic engines, and the support from Adrien and the team is excellent!

There is no Orion Support here in the US tho.

there is email support from adrien, and he will handle any warranty issues or defects as well. I have to say the orion rs is the most smooth usable powerplant I have ever used. The power is incredible to say the least.

I have not been able to get in contact with anyone in this company. Purchased an engine from THEIR website and didnt even get a conformation.

Update: I have finally be contacted by Orion. Their company have just finished going through an Org Change. For support you will need to login to their website and register your product....

Ive ordered a 3 port rs combo for buggy, what do people run in truck? Ive heard that 5 port can be...problematic? Would a 3 port with a pipe to enhance the bottom work?

The support OMFG make me laugh.... They are great engines, but there is no support, not even from Italy. In Vietnam we had 3 of the Cody King WC edition engines and 3 tebo engines. 2 of the Cody King engines and one of the Tebo engines never ran worth a crap. I emailed and emailed and emailed with no responses. the only response I ever got was from Facebook and it was to not post problems! I offered to send the engine back and PAY to have it fixed and returned, NO REPLY, I tried multiple email addresses to ensure it was going through and nothing. Finally I found a guy that did magnaflluxing and they did the cases, all three engines that wouldn't run had cracks in the case. They ran great when cold, but when they got warmed up they were hit and miss usually miss. I even sent the photos to them of the cracks, guess what... NO REPLY

And yes I emailed Adrein and got cough cough NO REPLY as well, he was even sent the pictures and a screen shot of how many times I emailed customer support, and from all three email addresses I used.

Token too bad my issue was well before they had the register your product on the support page, this was like 2 or 3 years ago that I had all my issues...

would you post pictures of the Magnaflux results ? I think its really interesting you found cracks in 3 of those engines, I think I have come across the same things but never had anything tested like that

I'm sad to hear that you had this experience, but did you ever consider that maybe possibly your email could have wound up in people's spam folder, seeing as you are in fact emailing from Vietnam? I mean, it IS actually possible, it's even possible that European mail servers block/filter any incoming mail from Vietnam automatically.

I know for a fact it is quite easy to reach him if you message him on facebook.
