Grey oil could mean water in the system!

I haven't posted in while but a new project has come along after taking her to the killpecker sand dunes I need to jet I'm sitting at about 7,000 feet above sea level.

Do I need to go up from a 240 jet or down a size due to my elevation? Since there is less air this high????

And the grey oil is from my clutch it slipped on me going up a hill and I can't gain speed after 3rd gear I've done leak test its all air tight did compression test about 120 is what I got.

And I might as well port and polish the head while I have it out!

Well I haven't posted in a while but I took the blaster to the dunes and I found out I need to get for sure and I need a new clutch! That's why my oil was grey has metal in it.

But I'm going to port the head since IMA be taking the engine out any way so yay! Lol
