rmd, when you bring it into the pits after a race does the engine start revving high (like being too lean)?

No it doesn't. Temp is between 240-260.

i usually lean mine off slowly until it starts doing that and then back it off. don't forget to keep adjusting idle as you change bottom end mixture.
just remember, by being too lean on bottom end won't damage your engine.

Sirio and bottom end.
 
RMD.....if your running 20% you might want to consider going to a plug like the turbo 6. I f think your performance will pick up alot with the 6 plug. If that doesn't do the trick, and the engine is not detonating(pitted piston dome) You could try and drop the head clearance by one .10mm shim.

Yes, I would go with a #6 plug for sure, maybe even a #5 in the winter over there. :lol:

Anyone know where I can get a piston and sleeve for a Sirio .12 Evo 2? I have one laying around that is collecting dust. I thought it would be fun to mod it and see what kind of performance I can get out of it. I tried ebay, sirio and trinity with no luck. Maybe a possible substitution? Thanks.
