Use Engine Ice coolant and ride faster :thumbsup:

I had problems spuwing coolant in the slow parts of the woods. I put Engine Ice in and no more problems. Don't ever let this bike sit and idle, it'll puke.

use Engine Ice or Silkolene Pro Cool, they work real well. Make sure to flush your cooling system every year, mix 50/50 mixture of white vinegar and distilled water, start bike up and get it real warm, drain and then put your coolant in. Flushing the system will clean out deposits and make your cooling system more efficient.
