Re: Put the big girl back together
as long as you have coolant in the overflow bottle you should be fine, just use your hand to monitor rad temp at top when she is running, it will start to warm up, hoses will warm pretty quick, not hot warm, I always run the bike with the cap off until I feel the fluid getting warm and it stays at the bottom of the filler, do not rev the engine with cap off or there will be antifreeze everywhere. Coolant gets warm pretty quick on all these newer motors. With the cap on once she gets hot enough to turn the fans on expansion will force some fluid into expansion bottle and any small amount of air will go with it, fluid gets sucked back when she cools
at 32 degrees F my cylinder head, not valve cover, is warm to touch in 90 seconds, she warms up fast not like the K100 and K1100 which take quite awhile.
