Well, I'm leaving the country on Sunday and will be gone for 2 months. Im hesitating on what to do: change oil and fill it with cheap stuff, and when I get back change it again with semi-synth before riding. This is what I normally do if the bike is left for longer periods. Since the time frame is so short, I may just change it with semi-synth now and ride when I get back. I'm going to drain the carbs and tend the battery so the bike probably won't be started for the 2 month time period. What would you suggest?
