    Any one have both the exhaust gaskets together

    Can someone put up the picture of a 1200 and an 1100 exhaust gasket together to show the water hole sizes ....??

    I can take a pic of both when I get to the house and email them to you in the morning.

    I think PW or someone posted one on here last year (of the exhaust manifold gaskets).

    The only reservation I have is that Bill Cosca doesn't recommend running the 1100 gasket on the 1200.

    I ran it last time and didn't see any ill effects, but Bill knows his stuff.

    does the 1100 gasket go open 1, closed 2, closed 3 ??? doesnt the closed gasket keep water in the rear cylinders longer and create more turbulance to pick up more heat???? or did the last two flow to much and starve the # 1 cylinder for cooling???? i know you tripple guys add more feeders to your cylinders and need that open gasket....(just trying to understand why yami. would have done this)

    so the 1200's are trying to run the 1 and 2 hotter (closed), to be more evenly cooled to match 3's hotter running cyl....so to run the 1100 you'd need to monitor your temps closere and adjust mixture accordingly...

    The stock 1200s also had staggered pilot jets. I'm sure that had some affect on the individual cylinder cooling also.
