Just finished a great ride that included a very nasty boulder filled canyon. Some parts of the canyon were first gear, feathering clutch, slow speed and it was very hot today. Boiled the rad fluid pretty good. Just not enough speed to get any airflow going. After she cooled down for a few and we got the hell out of there, everything seemes fine. Is there anything other than topping off the fliud that I should be worried about? Fresh oil? Is overheating this thing like that gonna kill it? Thanks in advance.
