Just recently got a new gadget, a borescope camera you can attach to your phone. I decided to take a peek at pistons in my 1995 SPX, just out of curiosity. Attached are the pictures of what I saw. I never really knew a thing about piston wash, but I did know how to read plugs. Earlier this year I did a plug chop, and the results were as expected, a nice tan color on the plugs. Now, I only know about piston wash from what I read on the internet, and most of that is from snowmobile forums. I am seeing clean portions of the piston right around the ports, but perhaps they should have bigger spots. I may be running a tad lean on my ski. Can you folks tell me if the piston wash indicates lean? Should I trust the plugs or the pistons more? Thanks in advance for your comments.
