I just got the bike. It probably needs valve seals, since it's blowing oil. I think it's stock... Beyond fixing stuff that's wrong, can someone point me to a list of the basic mods for these bikes, kind of "no brainer" upgrades? As I fix all the ratty stuff, I'd also like to make the insider upgrades - it's the cool thing to do! For example, on an xr400 honda, you open the airbox, ditch the snorkel, put on a K&N, grind the internal welds on the headers, drill the exhaust can open a bit more, rejet, etc. You can get a nice improvement just by letting the bike breathe better. On DR's, I'd love to hear what can be done right off to make the bike run and handle better. Thanks!
