I'm planning to take this bike through South America next year and have no plans to replace the leaking gasket.
I had the same problem with a 2003 DR650 I purchased with 4400 miles. At around 5200 miles the cylinder base gasket started leaking. I power washed the engine and then cleaned the site with contact cleaner and dried it with a heat lamp. I applied a layer of hi temp silicon and allowed it to cure for a week. A year later the bike has 13300 miles and not leaking any oil from the base gasket.
I recomend this quick fix
to anyone with a similar problem!
