Welcome! I'm up the hill from you in Nunawading so if you ever need any help/advice or whatnot give me a yell

The standard set up for an NSR is here:

http://www.nsr-world.com/tuning/250-tuning/carburation%20index/carburettors/

We can't talk any further about jetting or what not here in this area of the forum, but help is available in the paid areas.

I haven't done it myself but I do think it would be worth getting the workshop manual.

So do oyu know what model NSR you have? Any pics?
