200 Ultralite?

[KrAzyOSUcoWboY]

I have an 04 200 exc project bike and at 225 or so the weight is not bad, but I'm looking for ways to reduce it another few lbs.  I think losing 10lbs without undue expense for unobtanium parts is probably overly optimistic, but watching what the xr200 guys are doing it may more approachable than I imagine.  Possibly a couple lbs from early triples and 43s would be a start.  Any ideas?

Well, lights could come off, if you don't need them. All bolts changed to Ti($$). I'm interested in hearing of different ways though.
