I recommend the decompression valve mod for easy starting - and no more broken kick start levers!
Thank you to Larry Wiechman for your great workmanship :)
The lever broke at the base were it attaches to the shaft.
Cylinder looked to be in ok condition, I sharpened the edges on the walls between the main transfer and auxiliary transfer ports.
I noticed that there was some flash left over from the casting process so I had a go at cleaning it up and at the same time optimize the airflow. This is the first engine I've taken an engine apart so I didn't have much to go by other than what I could find online :s
I was pretty fortunate with the frame because there was no signs of cracking and the top exhaust mount bracket was still intact. There was a fair amount of chain rub on the sub-frame though, from what I can see online this is a common problem with the big KX.
The old pipe had taken a bit of a hit that caused it to foul one of the frame rails (arrow). I prefer a bare metal finish to chrome so would have been quite tempted to change it any way! Also circled is another broken bracket :(
The heavy vibration had caused the mounting bracket to break off so had another one fabricated, broken brackets was a running theme on this bike!. The outer seams of the radiator were also re-welded.
The old foot pegs and pins had got pretty worn and sloppy, the IMS pegs are also a little wider.

Additional Info
The bike was imported from the States last year - there aren't as many 500's to choose from here in the UK, I got my hands on it in September. The condition of the bike wasn't too bad - usual problems of chain rub to subframe and a couple of broken brackets from all the vibration. The bike is actually a '99 but I wanted to make it look like a '93, I was riding a KX 60 back then and really liked the graphics - this was also the swan song year for the 500 in the nationals.
