Hey Andy,
Thanks for the welcome reply! The NS250 Parts Manual is what led me to this site - much appreciated. That is basically the net sum total of what I have found out about these bikes. Thankfully the NSR is close enough to figure out some of the wiring and connectors and such.
Tough dealing with this rare of a machine, but that is what seems to find me. It's apparent there are few just by looking for previous sales records - both of them, haha. I did find one person parting one out in Ukraine, so the test-package is on the way - my Lt. handlebar switch took a hit somehow and it smashed the button off and cracked the housing Hope the parts make it because the switch is unique to the 250's.
Can't wait to ride it!
Warren
