I had a race last night and it was fairly warm out but not any hotter then a regular summer day. Practice and first motos went good. I was race 5 and 7 so I had time to come in after the first moto get some water and go back out. After the second set of motos I came in and noticed my bike smelled like coolant. It felt very hot and after it cooled down I opened my rad cap and saw nothing. Where did all of my coolant go? What should I do about running it so low. I really dont want to blow my motor so should it be torn down to check everything.
