R1ceboy is right, We are talking about a whole new ball game with the Sirio "evo2". They are factory mildly moded engines with performance at par with the newest generation of Nova based engines, so price is at their level, no kidding, these are serious powerfull mills.

how long should the fuel line be toward my engine? also the length for the return.

thanks in advance

Fuel line towards carb should be enough to get to it in a smooth way.
Pressure line should be minimum 10". The longer you do it from there, tends to lean the mid-range, so you have to tune it for your application.

Quick question for you guys.

Do you guys usually add a head shim when you run 30% with your Sirio .12 engines? I already know about using the cold plugs, just wondering if adding shims will be neccesary with this engine.

Thanks

Hey people
Any ideas where I can pick up a Sirio .15 with slide carb and sg crank from HK?

Thanks

Hi Au

which s12 crank do you need? and which slide carby as well? 2 needle or 3 needle??

PM me

I am after a crank to replace my broken sirio .12 one, but also trying to source a new engine - .15 slide carb, sg crank if possible

We have the crank. also s15 is use s12 carby as well if you still need one.

Hi,

Where can I buy a new conrod, wrist pin and clips for a Sirio .12 that will post to Australia?

You can get most Siro parts from Max tech Innovations

Cheers! Will drop them an email

Anybody...

Let me try

Not necessary. I used 30% trinity fuel, std shim and OS #6 & #7 turbo plug. check the plug condition after.

good luck
