    Was just finishing my engine assembly on my 860 rebuild, and something I never really noticed before. The head sits over the coolant jacket seal, but basically stops there, lol.

    I have a 15' summit X 800 and it is stock besides aftermarket clutching and exhaust with 2,000 miles ( warranty expired!)

    Looking at getting my engine completely rebuilt in my 800r Ptek over the off season. Just can't decide which route to take.
