Hope I can get some help and advice? On a trip to Mississippi last week, I blew the engine in my bike. Found it had lost all it's oil somewhere. Seen no prior oil leaks and had never needed to add in between changes. Had gotten oil changed, filter, tuned up with new spark plugs, valve adjustment cleaning of both carburaters. fuel filters, etc. Had used it daily for 2 weeks after with no problems. Just wondering if any ideas on why it would just seaze up? Oil light never came on and there was no warnings, runnig along about 1/2 throttle across open field. Thanks for any thoughts.
