I have a nsr 250 (MC21) and it is due for a service and a tune up very soon, I was wondering if anyone can help with this as i want to do this on my own as i have most of the tools to do it. I really only need the tuning specs and types of oils to use and so on. if anyone can help that would be good.

Does anyone have a copy of the service/owners manual in english yet?
