glad you like it
have you tried running it with the sirio 2611 pipe?

i only change my bearings when they start making that 'rough' sound.
i never change the rod.
has anyone ever measured the length of a new rod as opposed to a used rod to see if the rod has bent or lengthened?

Twiggy,

Did you measure the fuel lt after you heard that rough sound?(On .12 or .21)
After 8 lt at the conrod having a little space at the bottom where is the gold cicle.After that lt there is a breaking point at the gold cicle.

You wait till you race tune it
Then you will see something
Make sure that you wear a belt with your trousers

i know it was definately more than 4litres. but my other engine (evo3) has had more than 10 litres through it and the bearings are still fine.
it was a .12

I didn't have a chance yet, but will do so when I race again. I was racing a CRF today and also had to do some TZ break-in. I'm trying to do too many things at one time - but having fun doing it.

I need to ask a ques, im using a Sirio Evo 1 .12 engine on a FW05rr. I know it needs to use a different type of starter box to accomodate its engine placement.

From the looks of my engine, can it support a roto-start? I dont suppose so right? There's nothing to poke the rotostart into. But the previous owner mentioned that he used a handheld starter. Is there a handheld starter other than sth similar to rotostart that i do not know of?

you can use a r/c plane handheld starter like this one http://www.modelflight.com.au/buy_mo.../p7260184a.jpg
but you have to replace the cup on the end with a rubber wheel.

in order to use a drill type starter you would need a pull start style crankshaft. Most starter boxes will allow you to move the motor and wheel from a parallel to a perpendicular position. For instance the Kyosho box will start both on road shaft and belt cars, as well as the big 1/8th off road buggy/truggy. Using a starter box will be much easier than anything

Dear All,

I have a Sirio PR Pro and i am facing problems with the carbulator.
Can you tell me what is the default turns of all the screws?(Middle, Low, High?)

Thanks in advance
Nick

p.s. Sorry for asking so many questions

what the differents between a 3port and 5port Evo3 STI ?
cant decide which to get..
as i using Evo2 3port now

its time for me to upgrade

thanks

I think there is only one .12 Evo STI.
S12T3ISTI which is a 3 port engine.

it's the S12T5STI which is 5port according to the Sirio site.

Can somebody give me their clutch setting for low end torq? I m using RRR clutch with Sirio evo3 STI? How much is the end play supposed to be?

Check out the build tips at the RRR Knowledge base for how to set your end play. No matter what engine I use, my end play is always 0.10mm.
