E-man, you are correct...i must have had a brain fart on the inverted tubes. i would rather just swap a whole front end to include trees and stem, but cannot find a mx bike w/ correct stem size as xs650. so i thought maybe just the tubes and everything down.
if i could find a similiar newer inverted frontend w/ the same stem, then i could get everything i wanted. i could always have the stem changed out, but i would have to send it out for that and i would like to stay on budget.
as far as weight, i only expect bike to way 300-350lbs. me=175lb. i have found that the suzuki dr 200 has 35mm tubes from 1996-2003. however they are not inverted. here's a pic link
