In the Wee you might want to try Shell Rotella-T synthetic 5W/40. I'm loving it in the V-Strom!
I'm buying it at Wal-Mart for about $20 a gallon. Also available at most truck stops across our country! So when you're out and about you can always find oil.
In the KLR and KLX I'm running Shell Rotella, 15w/40.
Clean and Fresh is always good!
