ok so i have a 1984 ATC 200X. if all goes as planned, which im assuming will, i will have a DG exhaust, K&N air filter, Wiseco 10.25:1 piston, R&D valve springs, XR200 carb and intake manifold, ebay performance cam (http://cgi.ebay.com/ebaymotors/83-85-ATC200X-Camshaft-Hi-Performance-Cam-ATC-200X_W0QQcmdZViewItemQQcategoryZ43977QQihZ016QQite mZ260187816642QQrdZ1QQsspagenameZWD1V), and a frame up resto.

in september my bike sucked a valve, and killed the head and piston and it has been down ever since.

so my question is: Do you think i should rebuild the crankshaft (new vesrah rod, bearing, sprocket)? i kind of want to, but from what i have seen it costs $200+ to do it with the work and all. Also the rod will have more stress from the valve being sucked, performance stuff, and being 23+ years old, so what do you guys think I should do? thanks.

I think you might as well do it just to be on the safe side.

Check the tolerances. If its in spec why waste money??

eh....a 23 year old part that has moved up and down a gajillion times, then been rammed by the valve? rod kit should be about 50 bux on ebay, and it will prolly be about a hundred (if the crank is a 3 piece) to have the work done.

i would replace it. if you put it back together and it launches.........well, youll be very upset

i have a guy who rebuilds cranks for $45 he is in maine. it would cost you 16 to ship to him and back if your in the lower 48.
