Hello everyone, as this is my first post ever, id like to thank all of you for sharing your wisdom and knowledge with me. I have an 84 200s, great bike, daily rider. One day after a good 6 hour ride, i was about 1/4 mile from home running wide open on blacktop to beat the sirens not too far behind me. She locked up tight and shut down on me. Got way too hot and piston melted and I hid in the woods. So me plan is to rebuild it as a 200s, but I'm going with 65.5 mm 10:1 comp piston kit from wiseco, 200x cam and timing sprocket, 200x front and rear sprocket and chain. I did pick up a 200x head and cylinder just in case. The valves and springs are almost brand new on the x head, but I like the idea of comp release on my original cylinder. Can I bolt the x head on my honed s cylinder and use my s valve cover? i am also replacing the timing chain and tensioners/guides, same chain for the s and x? I also got a fresh 200x carb and was wondering about which exhaust would best let my bike breathe. Any info, ideas, warnings, advice anyone has to offer is greatly appreciated. I am a solid mechanic and I'm doing the build myself, but my info is limited on interchangeable engine parts and matchups between the 200s and 200x. Thanks again for any input, I'll be patiently waiting for my piston kit to arrive!
