The starter thing, IIRC, is for '98-'99 bikes.
I haven't seen much other than a few rumors/suggestions regarding the neutral switch thingy, although it has gotten some attention - a good thing. Mine was OK when checked a few thousand ago.
IIRC, the cylinder base gasket was changed to a diffenrent type in mid-year '03. Some, but not all, pre-'03 models have had some leaks. I haven't read where a leak on these models was serious enough to stop the bike.
Your '96 was the first year of the DR650 redesign and it should serve you well.
