    Can I unweld a welded super crank if the rod is damaged? Side to side play feels a little sloppy compared to the others.

      If that is YOUR crank, that rod is JUNK. Send the crank to Pearson & he will fix it.

          Yeah, maybe that's where the starter clutch bolt heads went. I have yet to find those. Maybe they'll reveal themselves when I find a moment to split the case.

            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.

              Thanks for that info, I'm a little bewildered to figure out my options. I have problems shipping things out and waiting, but that sounds like what I have to do. Doubt I'll get the parts shipped and back before winter sets in. Was hoping to do at least another track day. Oh well, wait till next spring. A 1360 might be a bit much for 2.5 mile road circuits, don't you think? Never been on a dragstrip, except at SIR while lapping the 2.25 mile road course.

                Carter, you may be able to cut the domes down to the same height as yours with these.

                  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.

                    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.

                        Split the cases and found more carnage. My starter clutch bolts have been found. They're tucked away neatly in this little tray.

                              Charlie that's on the Kat. Sorry for all the repeat posts.

                              Blower, missed the pm. Will look now.

                                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. Thanks for any advice.
