I've never broke my STI crank, and Mike Ellis also been running the crap out of his STI all season, at least 2 30 min Main and 1 45 min Main last Sunday, plus your normal practice and heats. He has no problem with his and still running strong, AND he hasn't even replaced the rod at all!

Yeah, you can say "But my Novarossi didn't break...". Well, tell you something, I started this year with a new Rex RER3, and a 1/2 gallon thru JP T03 full option. Those 2 motors crapped on me on their 2nd race and my STI has been strong. So "but my (other) motors didn't break" isn't a strong argument. Just because my Rex or JP broek and my Sirio still run strong, I don't go an assume Rex or JP are crap start posting on their threads.

I assumed that Kyosho America replaced your motor, to be honest us team guys get the same motor as anyone would, our motors aren't specially treated or made, they are essentially just "off the shelve" like yours.

Breaking one, I can understand but breaking 2... I'll have to say you might need to look elsewhere for the answer instead of looking at the quality.

Dom

never sed they where crap and i never sed that team guys get different ones, i think i know why they broke you have to run them diff than novarossis, gearing and soforth,and dont run them like novarossis i did say there damm fast,im trying to get the low and mid to fell like the novas but i should not do this.

lol just to say i broke 2 O.S motors too but not the cranks the pistons the same way i think all motors work you just got to find the right way to run them,and there all different

well I fixed up my evo2 motor and this thing is nuts fast.

If have a new (or relatively new) conrod (STI and Evo3), could you please measure points A and B as indicated below. I'm starting work on a .12 engine reference.

Thanks!

I have an older Sirio and it has the 3 needle carb.Does anyone know the factory settings or atleast a good starting point..I have no idea where to set the midrange..

Thanks,
Mark

I know this is in the wrong thread, i have posted in the want ads and am hoping for a little more coverage.

Anyone got the heatsink for a Sirio 21AAC WCR that they would be willing to send to Australia in exchange for a sum of money.
2 fins have vibrated loose on mine today and I am in desperate need as our nationals are very close.
Doesn't matter if it is scratched, be really nice if it is an M. Collari version as that is what It will be replacing (it will match all the internal initials that way).
I can pay by paypal.

Thanks for any help
