Or is there any online pages with set ups.

I'm not sure if this will help but my T5 172 is running on a standard 24/24 with a scorpion exhaust. I've upjetted the main to a 125. I'd say a 125 or 128 main jet would be a good start for your set up, everything else as standard. I couldn't see a big box exhaust needing a bigger main than a scorpion expansion. I've dialled out the mix screw a bit as well and I'm running a 21 tooth clutch. With a sito plus (122 main) mine would pull a 22 tooth clutch. Might be worth a try on yours. They are a great kit but they rattle in a big way! I'm mentioning this to ease your mind for when you hear your engine running for the first time. Smooth they aint!
