Ok, I for one, LOVE the simplicity of an air or air/oil cooled engine (especially one with screw and lock-nut tappet adjusters) But I've noticed over the years here that there are quite a few Inmates around who seem to hold the simple designs in contempt.:huh Let's NOT turn this thread into a L.C. vs air cooling argument. (that's been beaten to death already) I'd simply like to hear some stories about what bikes you've had that are responsible for converting you to.... THE WET SIDE! The only model I've ever had that over heated and shut itself down due to pre-ignition was a Honda XL650. (and that was even after it had jetting changes made to help the situation) I also had a 91 DR650 that would do the same (until jetting changes were made). Still, neither ever had a catastrophic melt-down, just minor annoyances to let them sit for a while before allowing the journey continue. Now, with today's NikaSil technology, I've not heard of many (more modern) simple-tech bikes, that over heat. I currently ride an air cooled 2011 TU250 thru city traffic on a daily basis and I've also had no problems with any air/oil cooled DR650's that I've owned since 1997 when they went to NikaSil. Anyway....tell us of YOUR air cooled horror stories, that led you to liquid cooled bikes. I for one, would like to know/better understand where some of my fellow inmates are coming from. PLEASE, NO L.C VS. AIR DEBATE...JUST STORIES!
