Well, I am rebuilding the topside of my '91 Yam SRV 540 due to what I have concluded is a too lean condition which burned out a head gasket and a piston (yep it is now a pissed-on) pretty badly (worse than I thought it would be until I took it all the way apart. Here is a link with more detail for those intrested:

Anyway, I have all my lovely new parts. Pistons (did 'em both since I went as far as I did...), rings, gaskets, reeds, etc. Already to but it back together and doh, I can't fiond the piece of paper I wrote the piston orientation on.
So does anyone know if the arrow on the top of the piston points to the exhaust of the intake side?
Thanks,
-Dave
