Moving on from the 350X....
Yes, this may sound shocking:
At 210lbs, even with all the suspension work on my RX, I find I can flick the 87 200X around like chicken. That aftermarket brace on top of the lower fork tubes makes this front end soak up allot. If I have to, I'll put 35mm 250R front end on it.
The 350X is much more powerful but the 12:1 200X is a rocket ship. Many thanks to Jason Hall with his jetting help (he doesn't have to think, he makes CHANGES!!).
The drags, I never reached 4th gear. The 35 rear sprocket killed it. I run a 38 now and I can run my track in 3rd 
The MX, I was fine but so weak and not quite healed yet, yep, I'm getting old.
I'm just in love with this 86/87 200X that is far superior than the 83-85 200X (Sorry, like it or start your own thread) 
What is it? 40#s lighter?? It is just so flickable (yes, thats my word) and I'll post up a video soon......
And, I can build 2 more!!
