If running water at 230 degrees is enough to cause trouble, maybe somebody should've told my Honda motorcycles. The VFR parked itself at 238 whenever I hit traffic on a hot day, the RC51 ran up to 249 and never ran cleaner or harder than when accelerating away from a traffic jam. VFR was 25 ethylene glycol / 75 water and RC51 was straight water.
Shoot, I should've told the guy I sold the -51 to that it was straight water! He took the bike from College Station to Virginia. I hope the bike's OK. I hope the rider's still among the living.
