FWIW I'm going to bug them about that and see if they will put plugs in the future... :)

Ok, so far I am not impressed with the Orion motor. I know these seem petty but in 4 years of racing I have never had this problem. Went to mount the motor in my buggy and noticed a piece of rubber sticking out of the idle set screw, after looking at it the Oring was sliced in half from the idle set screw being screwed into the case when they assembled it. So now I will have an air leak once I start breaking it in. Contacted Horizons and the guy was very nice and said no problem he will mail me a new one out.....Only 1 problem, they are backordered till late March:mad:

So my question is does anyone know what size Oring that is? Maybe it is the same as other Orion motors that someone may have in stock. If not that maybe I can pick one up at a local hardware store or even take from an older motor? I have plenty of old Vspecs!!

Im sure once I get thru this small stuff the motor ripping down the straightaway will make me forget all about it!! :)

Are you sure there not these?

If not, the whole needle and o-ring is cheaper than the bag.

The werks ring set should fit, but I'm not completely sure.

Maybe PK can answer this one better.

Just wanted to give an update on my Truhe edition Orion. I got a new Oring from Amain (thanks Pyromania) got it broke in just in time for this weekends state series race in Florida.

All I can say is WOW!!! This is the best engine I have ever owned. I couldnt have asked for anything better. The amount of power is insane and I have never had a smoother engine. I am very pleased :)

Another one will be ordered on Wednesday!!!!

Hi all! Which Orion engine has best fuel economy?? Thanks

I would recommend a Team Orion Alpha ABI 3-port. It will have the best economy, and it's got plenty of power. Cavalieri used it to win the Dirt Nitro Challenge this past weekend. Depending on the conditions, you can upwards of 12 minutes a tank, but it has to be well broken in before it'll achieve the best fuel economy.

Team Orion "CRF Alpha" .21 ABI Competition Off Road 3 Port ???
And which pipe and plugs did you reccomend??

Orion or Sirio 2013 and O.S P3 plugs.

The motor will feel a bit weak until it is fully broken-in at about 1.5 gallons. Then it has all the power you will ever need.:nod:

Agreed. The 2103 pipe works very well on this engine. The P3 has proven to be slightly fragile, so the team has been using the Sirio/Orion #5 or #6 turbo plug instead. The #5 is close to the P3 but seems to last a little bit longer, and the #6 is a shade colder, but certainly longer lasting.

I really want to try out the orion plugs, but none of the shops around me carry them.:cry:

Team Orion Domination
 

I want to congratulate Team Orion and Ryan Cavalieri on YET ANOTHER major race win. Pudge was on a mission in Arizona and won the Nitro Challenge Expert Buggy final in convincing fashion. This is a testament to the quality and reliability of the Team Orion Alpha ABI CRF line of engines, running flawlessly for all of qualifying and the 45 minute A main. Great job guys. :nod: I think you can attribute the reliability and consistent tune to the new aluminum body carburetors, they're fantastic.

pitpop:were you running the 3 port crf alpha in truggy class at the dirt nitro challenge? is orion discontinuing the orion sport $199,309.21 alpha, the .24 alpha and the us spec or are these going to be kept in production???

At NC, we ran a 5 port because it was well broken in. We will be running the new 7 port in truggy... I see all those products are in stock at Horizon, so I don't think anything is discontinued. I don't know the plans on that for sure, but right now everything is available.

does anyone know if the alpha crf 3 port piston / sleeve is the same as the alpha abi 3 port piston/ sleeve? I took a look in my 1 gallon old alpha abi and found the piston is missing a piece out of it :( . the alpha abi piston/ sleeve is significantly more expensive so I'm hoping for a cheaper fix . If not I'm wondering if I could grind the chipped part of the bottom of the piston smooth and just run it?

contact kyosho america too see if there is a warranty.http://www.amainhobbies.com/product_...ston-Liner-Set

I am using the Losi RE 10 pipe with the ABI 3 port. Would there be a major change if I switched to the Sirio 2013. Currently using GRP #5 plugs and getting 9:30 on a tank. (just started 2nd gallon).
Only issue I have is the LSN was very loose from new. I Changed the o-rings for a new set, but still have the same problem. Any ideas on how to fix it or anyone else have the same problem?

you should put 2010 updated carb on the abi 3 port and run the 2013 the pipe is excellent with that motor:nod::nod:

The 2013 will give you much more bottom end and some more top.

For the loose LSN, as long as it's not backing out or causing a leak then it's fine. On both my engines the LSN is really easy to turn, but I've never had problems.

Thanks Guys,

MP9er:
Why do you recommend changing the carb to the 2010 version. Is there a major difference in the performance or tuning?

Not experiencing any problems with the current carb.
I have a 2053, JP3 & GRP pipe from .21 tuned combo I have. Keen to try these as well. Not sure what each one has to offer as far as power and consumption is concerned.
Should I change the glow plug to P3?
Thanks

the tuning is more consistant i ran the stock carb for little and changed to 010 carb and it was heaps better

The 2013 will give you the bet performance, bar-none. I tried a few pipes (jp3, 2035, and jp4) and none gave the same performance or run time as the 2013.

If you can get your hands on some Orion #5 or #6 plugs, I suggest you pick some up. Otherwise a p3 will work just fine.

well
 

i have a 3 port Orion motor with a JP-3 pipe and i have been running this thing with 30/9 byrons since about a week before the Futaba Nitro Challenge and its still has enough pinch to where i cant turn it over by hand the only thing i changed was i put a O.S. speed card on it but i couldnt be happier for the price i paid and the bang i got has to be the best motor for the $ i ran 9:30 mins in one of the mains at the Futaba race

Thanks Joe

myst38.. if your composite carb is working fine then no reason to switch it. The new aluminum body carb is just more consistent from engine to engine, but if your composite carb is tuning ok then you're fine. We had a few of the composite carbs that worked well.

dandrat.. sorry it took awhile to get this answered, but the new CRF 3 port sleeve will not work in the older engine, the top of the sleeve is taller and wider than the old one. On your engine repair, you actually need to talk to Horizon Hobby, as Kyosho America has nothing to do with Team Orion customer service any more. I would highly suggest talking to a customer service technician first before sending it in. Horizon's number is 1-800-338-4639.

I found putting my o.s. 28 carb on my alpha works 100 times better with the tune staying consistent,I just set everything flush on my extech and then tunes it in and pit it on my Orion and it was spot on and worked much better then the stock carbs. I however have not tried the updated 10 carb that u sponsored drivers have.

The new carb is available and can be found on all the new ABI CRF model engines. They seem to be out of stock, but surely they will fill these orders and become available some time soon. Here is a link to the new aluminum body carburetor: http://www.amainhobbies.com/product_...ete-Carburetor

Hey guys,

I m looking for a new motor for my 2010 season and i m pretty interrested about the orion.

Any one can confirm me if the 3port ABI Alpha can able to run 10min ?
Same question for the MTE 5port

Thanks

We can get the engine to run 10 minutes, but in order to pit at 10 minutes, you really need to go 12. We have run near 11 minutes on a tank with the 3 port in testing. The 5 port I don't think will do it, maybe 9:45.

thank you! fast answer!!!

so for track with aprox 30-45sec laptime the 3port was a good choice to pit at 10min right ?

Pitpop: thanks for the info.

I am shopping for the 2013 pipe today as well as orion #5 /#6 glow plugs.
The carb is not giving me any problems and running 9:30 - 9:45 on a tank, so I am pretty pleased.
When tuning, I usually do the pinch test as a final check on the LSN, then richen 1/8th of a turn. The only thing I have found is the engine never loads up. CAn idle for 30+ secs and still explodes off the line. Should I richen the LSN a bit more?
Thanks

if your pinch test is giving you 3 to 4 sec before it stalls thats about where you want it any longer you should lean lsn a tad but if your motor starts to cut out your to lean

2013 PIPE
 

I can't find the Orion 2013 pipe, is the Werks 2013 pipe and header identical?

Thx

yes its the same.

http://www.amainhobbies.com/product_...old-2010-Model

The engines run well with lean bottom end. Get it good and hot, then do your pinch test and leave it.

when you tell cody ran 11min is with the fuel line pressure cooler ?

Thanks

I'm not sure what you mean by "cooler." This is mostly done with tune, but using 7mm insert, Byrons Pro Blend 9/30, and smooth throttle finger. Nothing special done to the pressure line, we just run a normal pressure line set-up.

Hey guys, I am looking at getting either one of the 3 port alpha motors (turbo head/ ceramic bearing or the CRF). I would like to know which is getting better mileage, if there is a noticable difference. Also is everyone using the 2013 pipe on the CRF or something else.

The 3 port engine gets the best mileage. 2013 pipe is definitely the one to have.

About to break mine in. What is the best orion plug to use for that. Im in so cal. Thunder alley local track

Anyone know off hand the sizes of the front and rear bearings on the CRF Alpha MTE engine? Thanks

what is the 2065/2066/2013 orion pipes mid-top,bottom mid ECT? what did cody run in truggy buggy at SS?

and congrats to cody pitpop!
