Pulling the carbs this weekend to clean and re-jet for the mods that I am doing to the Z.

Cudney is porting it, supplying new piston kit,VF2 reeds,and including gaskets.

Going to be running Dynoport triples w/can.

He suggested to start the mains at 400. So, I purchased three sets of mains.(360's.380's,and 400's)

This sound like a sgood place to start?

Engine will be in the 185-190hp range and have about 150psi compression.

I ride at about 400-900ft ASL, and temps are usually no lower than 0*F.
