Hi , you need :
- 1 main jet 138
- 1 slow jet 42
- 1 power jet 65

from https://www.dellorto.co.uk/. When you change the jets you also have to set the throttle needle at 2nd notch from the top

Looks good above. https://www.dellorto.co.uk/merchandise/products_details.asp?PartNo=NSR%20JET%20KIT&CategoryID=2&PartsectionID=24

Quote:
if you have the dellorto PHBH 28mm carb then there is a specific kit for rejetting it. then only thing is, its probably designed to work with all restrictions removed at once.

removing airbox and exhaust restrictions will mean new jetting. i think it will run lean if you dont rejet.

bear in mind this is only for the dellorto PHBH or PHBL carb.

just did it myself, the NSR is the first bike I've taken apart and it took me less than 2 hours. You really need to change jets as if you remove exhaust and carb restriction the bike will not run right as Steven said. I put a few pictures on there

if your bike is a JC20 (1989-1993) the jetting is OK
if your bike is a JC22 (1993-2001) the jetting is poor
download my file https://www.geneva-racing.ch/~alains/NSRtips.doc and you will find anything you need
