    Let him keep listing it. OR take $250 and dangle it in his face.

      That engine must be the same one as on CL - from Stanton. http://orangecounty.craigslist.org/mcy/964199373.html Guy has been listing it over and over again for more than a year I think - he wants $400 in his ad. Not sure it's worth that much unless it can be certified as low mileage. Going to give him a call.

      Edit: guy said he will come down to $350 but not lower. Seems a little high to me but what do you guys think? He claims the mileage is in the teens but there is no way to varify.
      I bought an entire bike less bodywork for $300, with a title

      He can't be serious, listing it for a year?

        Pistons look like Wiseco. Is the a little W in an oval on the pin boss?
        If it is an 83 with scored walls, you may be able to clean it up to a Wiseco 73.5mm

        Years ago, there were American made billet blanks for the 1000. Is there a CWC or CMC cast in the cams any place?

        As far as the broken guide, retainer, valve springs, that is not a problem. We have parts for replacement.

          Thanks Jay.

          Pistons are soaking in carb dip right now but I think they do have an itty bitty W within a circle on the pin boss.

          Speaking of pistons, They don't look too bad other than that one that has the smashed edge shown in the photo. Tried one of the good pin buttons in that hole and it seems ok. Do you guys think it's crazy to consider using those pistons again?

          Regarding the head, my concern is that the valve spring bucket bore is chewed on a couple of the holes. The rough edges could be smoothed out but not sure this is a sano thing to do.

          Split the cased tonight and thankfully, everything looks ok as near as I can tell. The crank has some funny looking hammer marks on some of the pork chop weights but other than that I don't see anything unpleasant. It's about time something went the way it should.

            They will be easier to sell if you ID them. Look on the very end of the cam for a number. I have charts for web-cam, andrews cams and cam-motion cams on hand. Measuring lobe height is not the way to determine lift as some of the larger cams were ground with a smaller "base circle" to keep them from hitting the valve cover. The cams you have look to be over .400" lift to me. Anything over .400" lift requires the use of "shim under buckets" and titanium valve spring retainers....Not aluminum.....Billy

              To measure lift I supported the cam in V-blocks and put it on a surface plate. My dial indicator doesn't have enough travel so I used a surface gauge with a pointer to find the height of the base circle and at the top of the cam lobe. Measured the height from the pointer to the surface plate using calipers - yea I know, not the best method. At any rate, the cams measure right at .400 give or take a few thousands. The engine never spit out a shim so I assume underbucket shims are not manditory for this cam. Agree with your comments about aluminum valve spring retainers. The question I have is which broke first, valve spring or retainer?

                The springs break first & then beat the crap out of everything else! Ray.
