thank you bro..

Andy who? 03-21-2008 04:59 PM

Ok, while I'm looking through here I'll just ask.
Can someone telll me the part number for a .12 Evo2 rod?
Is it the same as something else?

saptar 03-29-2008 12:59 AM

thanks for the help after a few hours or tunning it is almost running right but we have hit a wall. i think i will get some one who knows what they are doing to tune it.

How can you id a sirio motor? Only markings i see is the atom and .12 on the head. Made in italy on the body. It's got a black 3 needle adjustment carb, silver restrictor , turbo plug, 3 port, i think thats about all the info i can get off it.....:confused:
Oh, and the sleeve was silver....so i'm guessing its a AAC
Searched all over the place and can't find any info.

must be old? , sirio havnt made an aac for year or 2 in a .12

Roelof 04-19-2008 12:56 AM

So far I know the AAC is used in the .12 EVO2.

I wonder why Sirio is not using the AAC setup in their current topline .12 engines.

Baedarlboo 04-19-2008 05:38 AM

I know it's not an EVO2 as it would be printed on the head if it were, right? I don't have a clue with these engines so.... Is AAC a good thing? The motor runs like an raped ape, so i'm trying to figure out what it is exactly so I can buy appropriate parts, or at least compatible parts. I'd like to keep this engine for a while.
So, are all the .12 parts interchangeable ? Can a complete set of internals fit into any case?
Any sirio gurus out there that can help?

Baedarlboo 04-20-2008 07:23 AM

LOL
Bueller? Bueller? Bueller? :lol:

Thanks....I'll take pics and post and post when i get a chance to pull the motor off the car and take it apart. The heads blue, on one side is a small atom, on the other side, is a .12.....no evo, and no design all over the head, very simple. The case only has a made in italy stamp.

Does anyone here run a CL7B in a 1/8 scale buggy? If so about how much run time do you get?

Baedarlboo 04-22-2008 06:35 AM

OK, then what are some of the .12 motor's that have compatible internals? Older Sirio's included. I just want to know what internals i can replace mine with and where to find them...
