I think a better question would have been what did someone have done to the tranny.
The 200R4's can be built from anything from mild to wild and have a price to match. If you want a good street fighter you only might want a shift kit, aftermarket clutch pack and hardened statter (sp) and possible a newer style pump.
It might be a better idea to decide what parts you want or how strong of a tranny you want. All I had done to my tranny was the parts I mentioned above and back in 1990 or so, and I had the shop pull the tranny and do the work while I waited.
So I think asking what someone paid with out a list of parts would be a more fair question.
Good Luck
