Hi James - I live in Ontario Canada and have the same NSR 250 as you do ( hope you still have it )
I would like to know how you made out with the 030 card ??
I have the 030 card , expansion chambers ,carb pods and wire splice completed and was wondering if you managed to get yours done and if you needed to do anything else to get it to run properly and to your satisfaction ?
did you need to do any carb modifications ??
hope you can help
Piet
