Mike, you can just search www.taobao.com and use CG200 as your search phrase. Use Google Chrome and allow it to translate automatically. After several pages, you'll eventually find some interesting pistons for cheap.

If they're the correct dimensions, why not replace them? It strikes me as a good idea. You could even lap them into the seats.

I compared the valves today. The new ones look slightly smaller hope valve seals are right? I can just lap the old ones while I have them out. What about opening up the exhaust port a little?

The valve seals are likely to be correct, but it's only a guess. I wouldn't open up the exhaust port, but I'd clean it up. I might even polish it.

To be fair, cleaning up the exhaust port effectively essentially means opening it up. While I wouldn't hog out the diameter of the port exit much, the port itself requires quite a bit of "cleaning" to open it up lol. The casting around the valve guide consumes so much of the exhaust port that it's a bit comical.

Thx for replies. How important is it to clean the centrifugal filter? I ask because previous owner had to extend the kick start shaft by to clear the frame to make it functional. The shaft is welded along with the kick start lever. I ran the motor very briefly with valve cover off and oil is pumping to the top end nicely. Is this an actual screen? Someone plz explain what it does? Thx

The kick start weld looks nasty. lol If you don't need the kick start you might just have to wack it off and get another shaft.

You're welcome. Be sure you file any burrs after you cut it. You don't want to wait 3 months for a new seal to get here. Going this far, have you checked the rod bearing? It is a roller bearing, and can have a little movement back and forth, but none straight up and down. You don't have to put a lot of effort in lifting it. I used to just put a finger in the piston pin hole in the rod to check it for slop...ARH

Got the motor back together. The valves ended up fitting fine. Did 3 10 min heat cycles per Duncan racing then changed the oil. Adjusted valves. Have 153 psi as of now. Good thing I cleaned out the filter under the side cover. That thing was CAKED with grim/crap. Gonna start riding around the yard to break it in more. Sounds pretty smooth for a push rod motor. After I know it's running good I'll start working on the details. Exhaust it def on the list.

I'm sure your right. I'll post a pic. It's on a grey oil mat so it's kinda hard to see it all. Rode it for 10mins at up to 50% throttle. Running good! The breaking up and having to run it on 1/2 choke is no longer there/needed running way smoother. I will still have to jet it in in the spring. Over the winter I'll do a lot of cleaning up and adding some new parts! Appreciate everyone's help!!!!!!! Oh ya is Australia the only place I can get that head pipe I need?
