I just picked up stock Bandit block for $50 and I had a set of Busa pistons that I paid the same for. I am going to press the Bandit sleeves in the GS1150 block and bore them for the Busa pistons 81mm is the 1st bore on the Bandit sleeve and you end up with a 1360cc motor. If you have to split your cases anyway it is a inexpensive way to get a bigger motor. you do have to bore the cases also and deck the bottom and top of the block.
Just something I thought you might be interested inMy stable

Ray I saw those, but then noticed the ratio. Couldn't I buy 1 new 10.25 to 1 from MTC? Seems like the material under the dome wouldn't accommodate milling the top off. Would a higher compression ratio piston actually have more material under the dome? Also weighing the same as the other pistons, isn't that a concern.GS\'s since 1982: 55OMZ, 550ES, 750ET, (2) 1100ET\'s, 1100S, 1150ES. Current ride is an 83 Katana. Wifes bike is an 84 GS 1150ES

In my experience with the MTCs like those, they are NOT a hollow dome & can just be milled to the same dome height as your existing. The next concern would be if the valve pockets are the same size as yours & then just to balance them. I would just ask the seller questions before the auction ends & ask for an inside picture of the pistons.

Talked John Pearson today. Will ship out the crank this week. Didn't have a moment in the conversation to ask about cylinder boring. Does he do that as well?
He's not an easy guy to get a hold of. Still have to split the cases though before I ship.GS\'s since 1982: 55OMZ, 550ES, 750ET, (2) 1100ET\'s, 1100S, 1150ES. Current ride is an 83 Katana. Wifes bike is an 84 GS 1150ES

Sent the crank off on Saturday. Pearson said, 2 week turn around. Looking for recommendations to send a stock cylinder for boring. Would folks suggest sending a piston to match the bore? Is APE my best bet or could I have it done locally.
Regarding the compression ratio, could a thicker head gasket theoretically reduce compression by .25? Somehow I recall hearing that ratio when I bought the big bore from "Heads Up" formerly in Las Vegas, now in Utah. Maybe it was a 10.5 to 1 to begin with and my recollection is fuzzy.
