please have a look and tell me what you think
guys pulled head off last night to get head skimmed and to have a look before key and vf 11 go in and replace head..the ski has 60 hours on and looks to me to be far to rich but the e.f.i has only been on for 3 tank fulls proir to head pull..can you let me know what you all think..hope i caught it in time if far to rich my e.f.i is not set correct yet but my settings have not been above 22.214.171.124 last run steved and i were pulling the 5's down to 3'
these are engine mods to date
riva filter no sock
reed stuffers hence the vf11 now
lots of air mods
also run on yami lube so expected to be lots of carbon deposits

One of the EFI gurus should chime in shortly over your EFI piston wash
Trager, WFO, Abbott, where you at

Looks a little rich, but it is fine.
Did you wipe the tops of the pistons ?

it does look a little rich. i think there should be a tad more black to it

Before you go any further i would sit down next to your ski and have a cool beer
Looks a bit rich but a few clicks on the EFI unit will sort that out ! Good to see the start of the brown piston crowns .
Good luck with the next mods catch you soon .

I'm no EFI guru, so don't take my advise, , but doesn't almost look like the PTO cylinder is soooooooooo rich that it's washing the piston top clean??? (mostly clean)
(additional disclaimer: I have zero knowledge of the EFI's!!!)

The reeds alone with same efi settings just might cure that instantly.
