I want to take my 2007 Kawasaki Ninja EX250 Cross country on the slow scenic route from Maine to Florida next fall & i am wondering what recommended maintenance i should consider before taking this challenge? The engine has 24,500 miles with about 6,000 miles on the engine head and head gasket. The bike runs strong and does not burn oil after replacing the head myself.
its about 4,000 miles there and back, any recommended preparation maintenance i will take seriously. the bike doesn't burn oil but i am considering replacing the pistons and rings to have a fresh start on the engine but i also don't want to possibly create an oil burner on a non oil burning engine if the rings don't seat properly, is this even necessary? Please let me know what you all think/suggest and or recommend! Thanks All!
