If you will know what that Sirio is and by whom it is prepare and where, you will not make equial line. Also one Sirio won and three broke-it is 1/3 ratio.;) :nod:

.

In fact, I do make p/s sets for 21 and 12 engines out of BRB and a lot of people saw my products yesterday and everybody was ammazed of them. You can find out easy from a lot of people who was there. BTW, on Winternats in Florida my product was shining- check around and people will tell you what I am talking about.
About Josh's engine, he didn't have any tuning problem at all. he got mechanical fail on engine and it was keep blowing plugs ( at list 4 or 5), which give enough clue to say that conrod is gone or piston cracked, btw, are you sure he wasn't running LCI? I saw what he was running, on his pit table, did you see it?:nod: :D :lol:
Please notice, that my coments here to not drive down the brand, I hate when reps are blaming racers for engine failuers-run in was done wrong, too lean, too reach etc, etc etc.:D

If he was running LCI engines, then they were not Sirio. LCI works with Rossi engines. If they were Sirio then they have to be LCM.
BTW you can also constantly blow plugs with bad fuel and/or wrong co´mpression ratio,not necesarily conrod or piston failure. At any rate the only one that can answer that question is Josh himself. Lets not jump on to conclusion so easily.

This is exsactly what I am talking about. :D :D :D :D :lol: :lol: :lol:
Rep always blame racer in engine failure.:D :D :D

.

Unfortunately, you even can't read the posts, I have never sad that plugs can be blown due to the wrong compression ratio or fuel, it was AFM. So, start from here the rest is BS.
Yes, my native language isn't english, I came from Russia and I learned English here. Even that I can separate by looking on the posts who sad what!!!!!!!!!!!!!!:lol: :lol: :lol: :lol: :lol: :lol: :lol:
BTW, if you know Josh, ask him about me, you might find something very interesting.

Hey guys, lets cool it down and put things in it's real proportions. This whole issue started by somebody posting a picture of his broken crank, and questioning the quality of Sirio engines.
After observing them I posted my opinion that it was caused by long periods of overheating, which was then admitted by the owner.
TG you jumped in, selling the idea that Sirio engines have bad quality and that Nova based engines were superior blah, blah..... and somebody else, posting pictures, said that not only Sirios break but also Nova based engines do, if mistreated and or badly tuned, idea which i support and also that there is no perfect engine.
You are a manufacturer and I bet your engines have their share of problems to, but it is not ethical for you to induce a thinking that every engine out there...except your's..... is a piece of $%&&.
Give constructive advice, because you are not going to sell more engines by trashing the competition.
State your strenghts and prove them on the track with results, and help others, if you wish, giving advice on how to avoid desaster, but not throwing $%$& with a fan over other brands.
AMEN

Good, to know, that you saw me with Josh and I realy don't care how do you know that.
If engine turns, it doesn't mean that conrod is OK, it might not be broken on pieces, butif it loose on pin ( ery common problem) it will be creating a lot of debry,which is going to combustion chamber, light up ( there is enough temp to light up AL) and burn out filament of glow plug. It also can be AL sleeve got loose in case and creating Al debry, goes to combustion chamber etc. It is still mechanical failure.
Whatever reason was, but there were more broken Sirios then Novas-this is bottom line. So, I still saying that Sirio is much less reliable then Novas based engines. In the mean time they have some very good design ideas there.

You didn't insult me at all, don't worry about it.:D :D :D

Actualy I wasn't against Sirio and I sad, that reps always blaming racer for engine failure and you are the Sirio rep and you are doing it.
You can do as long as you want to, but it is not ethical to balme racers in everything.:D

.

It isn't true that reps "allways" blame users and/or racers for engine failures........ here you go again asuming false conclusions. Sirio and other brands, and I've quoted several examples (JP, STS, Nova Sirio, etc, posted in this forum pages), have replaced any damaged engine or part......... when failure is clearly by bad production failure, but not when you can clearly see it is by misuse or abuse........and I bet you have same policy...or are you going to tell me now that you give unlimited guarantee over racing engines????? Show me a brand that guarantees racing engines of any kind.
Yes I agree with you on not being ethical to allways blame users for all problems, but statistically it is most of the time by abuse or misuse that problems ocurr, and that is when serious tech support comes on the game, and makes the difference in brands.

AFM

Well, to say the truth, if you bet on my policy you lost already. I have no limited polices on exchange of the parts, there is only one policy-if something went down-it wasn't strong enough. I don't guarranty normal wear and tear, but everything else, even if anybody can prove, it was abuse, I change it. Even it was instance, when, the racer couldn't pull out sleeve from case tryed to use screwdriver to take it and ruined the sleeve, I chanaged without question. I know sound is stupid, but I do change broken parts with no investigation of cause and blame for too lean or too reach. I am defently asking how it is happened, but it is only for developing point. try to find where is weak point is and find right solution for it. Yes it was couple failurs on the very beginning of 12 size piston/sleeve sets, but I got right picture how it is happened, we change alloy for piston and guys who had roblem recived new sets without any cost for them. I can easy prove it was too cold running ( my sets hate to be cold and I noted them it), but I don't do. I just see it this way-if you pay money-you have to have fun.
This is my policy.

Yes, the LCM indeed has a ton of HP. But how much is it? I believe it is almost twice (maybe over) than Sirio Evo2 price. So you can't say Sirio produce higher performance engine with less price compare to Novarossi. Sirio with Sirio-based LCM is totally different story...
