  • And the Journey Begins

    I have all engine parts cleaned, sand blasted, and pressure washed to remove any left over sand. Many air blasts to remove stubborn, hiding sand. and pressure washed, and fresh water rinsed again, followed by more air blasts. The cylinders have been bored out to accept a Wiseco 1179cc big bore kit. Next, all parts have been sprayed with brake clean to remove any oils that have contaminated the surfaces from my handling of them, and the first coats of VHT engine paint has been applied. Each piece will recieve four coats of paint, and then will be subjected to one hour in the oven @200 degrees to cure the finish. I'm afraid the the cases won't be baked because I have a small oven and a big engine. The head, cylinders, and all covers will get the heat treatment though. I'll have to hit the cases with a couple of hair driers. All cylinder head stud nuts, case and cover bolts have been polished on a bench grinder with a wire wheel, and polished with Rub N' Buff Silver Leaf (WOW!). Next step is the polishing of the covers that are to stay silver. The valve, ignition, alternator, clutch adjusting, starter, and middle gear covers, as well as the cam chain chain adjuster, and the oil filter cup and oil cooler adaptor will get shined up with polishing compound and Rub N' Buff. The cooling fins on the cylinders and the head have been filed flat, and sanded smooth, to make paint removal easier. I want the edges of the fins to shine.
    I have take some pictures of all of the cases, covers, cylinders and the head before painting, and will take some more in various stages of paint and reassembly, and then I will try to learn how to up load them to my ISP, and post a link to them. I have a new $1000 computer, and I better learn how to use every damn bell and whistle it has.

    Wish me luck!

      Do me a favor, measure the wall thickness at the bottom of your cylinders and post the results here.

      I was talking with the guys over at Superior Sleeve about whether or not the XS11 needs to be sleeved for a big bore kit. I was told that as long as the sleeve was 2~2.5mm it should be OK.

      Anyway I’d like to know so I can either be right to eat crow on this one. ;o)

        Tony,
        I have no way to measure the thickness here at home. I do know that the guy who runs the shop where bought my pistons, says the sleeves are ok for the 1179cc bore, but he doesn't recommend going any bigger than that. The new pistons are 2.5 mm more than OEM, so I think that makes them 75.5mm, but I'm not certain.

          I checked a sleeve in my spare motor out in the shed - it measures 3.5mm thick

            Is that stock or over bored?

              I'm pretty certain that is stock, Geezer, or at least not a Wiseco overbore kit size. I'll put the micrometer on the cylinder bore today and confirm...

                Confirmed - that 3.5mm wall thickness measurement is for a standard bore (71.5mm) cylinder.

                  Well then,

                  The 1179cc big bore has 74mm diam ring sets, so 2.5mm more in total diameter is 1.25mm from the actual wall thickness. Starting out with 3.5mm, you have appx. 2.25mm of wall thickness left.

                  PHEW, I guess I'm safe for now, knew there was a reason why I didn't want to go for the 1196kit!!!

                    The diameter is 74mm for the 1179 big bire kit. I looked at the box to confirm the size. I just put the first piston on the rod. What a PITA the circlip is! All engine cases and covers have been painted and the cylinder and head cooling fins have been scraped down to the aluminum. WOW! It looks great. I did a mock up assembly tonight, and it looks incredible. I hope it runs half as good as it looks. I even let SWMBO help put the shift drum and forks in tonight, and she'll be helping asemble the rest of it, when the trans gets back from the machine shop on Monday.

                      While this still sounds a little thin to me, I have it on the authority of the best in the business that it's inside the safe zone.

                        The harder it is to put the clip in means the less likely it is to come out. Did you go for the sprial wound ones? I first ran across them in snowmobiles. They never pop out in service unless everthing else goes to hell first.

                          The circlips are the ones supplied by Wiseco. They seem to be just a peice of spring steel, but I don't think they'll pop out. They sit fairly deep in the groove. I did the last three at work today, and each one got progressively easier. I was disappointed when I only had three to do I may get the crank in tonight and if all goes well, the jugs and head can go on too.

                            Detour along the way

                            SWMBO and I were installing the crankshaft last night, and we noticed the #2 main bearings were missing. I had them tagged, and bagged in seperate ziplock bags, stored in an empty latex glove box, similar to a kleenex box. My error...was to not lock them up in my tool box when my work shift was over. I was doing what we call a 'G-Job' at work. I had taken the crankcase halves to work to soak them in the parts washer, and then sand blast them, so I removed the bearings, and forgot to lock them up. One of the 'children' at work thought it would be great fun to pi$$ off Wilmot, and they removed the bag that contained #2 main bearings. I had to go to the local, 'factory authorized rip off artist' and order new ones...$14 per half!. Another bump in the road today was when I was checking the end gaps and installing the rings on the pistons, and I broke the second ring on #3 piston. Call Wiseco, $25 plus shipping for a new set... Transmission is home and ready to be installed, so we are off to play mechanic...

                              Progress report

                              Trans is installed as are all other bits n' pieces. Just waiting for Wiseco to deliver the rings and Yama dealer to deliver the main bearing. Waiting sux. I was hoping to be swapping engines this weekend. SWMBO wants to assert her dominance one last time before the rebirth of Twilight Special, so it looks like this weekend will be her last chance. Can you say 130+ mph? If it breaks, so what? I sold my XS750SF to a guy that has a motorcycle towing business, and he gave me a free towing card. Besides, I have another engine just waiting, no, Jonesin' to replace it. I might just be removing the old one sooner than I think. I may have to remove the big windshield, just so's I have a snowball's chance with that FJ1100. I hope she don't break. I've spent $800 on mine already, and can't afford to spend any on hers. That would be a bummer, her bike broke and just sitting in the garage, and mine still running
