Your stock jetting should be pretty close, if not already perfect. It has the tuned exhaust so that's not going to matter. The only thing changing will be the compression ratio. That usually doesn't affect mixture much.

you had mentioned you were thinking of going to a mid 90s looper head... and for sure that wont fit onto a crossflow motor...

$125 each

Looks like I got some work to do if I want to get back on the water!

:)

Also gives me a reason to take a look at the pistons

This adapter plate is a strange contraption!

Installed some new gauges and painted the dash (head temp -- water pressure -- head temp)

Pulling the powerhead
