Well let's see how well I can track the rebuild of my 83. I think it is an 83 at least. Maybe I should check the title again. Either way I purchased it from a buddy of mine. He had it for a few years and it was supposed to be in good running condition until the charging system went out on it. I think he let it sit for a year or so before he contacted me about helping him sell it. I told him for the right price I would just take it off his hands. We settled on a price, and it came on home with me. He already had a PMA and ignition setup from XS charge new in the box that came with it so I figured it would be an easy task to get it running. Messed around with it for a bit before deciding to go ahead and rewire the whole bike while I was at it. Once I rewired it and had all the new xs charge stuff installed I finally got it to running. Somewhere in the middle of all that is when the fun began! For the life of me I could not get the bike to fire. Finally figured out the timing ring was in backwards, and from the looks of it I still think it should be the other way but ehh whatever. Now that it is running every now and then there is a loud backfire from the right cylinder. So back to troubleshooting I go. Check the coil. All is good there. Check the valves. Adjusted and all good there. Check the carb. Ehh decently clean but not reason for it to be the issue. Fire it back up just to let it run a bit and the right cylinder is just dead cold with the occasional backfire which sounds like someone sending a single 5.56 round down range. Only thing left is check the compression. It would only build 20 psi or so before bleeding right back down to 0...... Now I'm in the middle of a full rebuild with a 750 kit from XS Performance, Shell 1 cam and Kibble White spring kit from Gary Hoos, and a beautifully redone head from Daniel at Pandemonium! Going to post some pics of it from along the way along with continuing to update the thread with my progress. Here is how it looked when I picked it up from my buddy.

I like the direction the chopper was and is going. Is that a Knuckle/Pan in your profile pic?

Looking neat and tidy, good looking box. I learned the hard way batteries hate vibrations and these bikes have them in spades. I mounted my new battery on a piece of high density foam.
Thanks! I didn't want to run a battery, but there is a chance that my wife will be riding this one some so i wanted to make it easier on her. All my other's just run capacitors.

I could see the pan on the rear cylinder but the front is a little fuzzy and makes it look like a knuckle. I’ve actually seen one with dual heads and thought that may be one also. Very nice!

Well, here it is all blown apart. I'm currently putting the motor back together. I still can get over how awesome the head looked when it came back from Daniel! The reassembly pictures will be next.

We are getting somewhere! Cam is actually in and timing chain on. Rocker box is next, and then it is time to break out the torque wrench.
