I am new to the jetski scene and dont know much about them and just recently purchased a 99 kawasaki 900 stx and wanted to know if it uses just straight fuel or does it need to be mixed and what octane would be good and also any tricks on starting it on a cold start

Google .... 1999 Kawaskaki 900 stx.. owners manual ....There is an oil tank for the oil ... not premix unless someone "rigged" it...
Some people swear by non ethanol fuel ... others are not so picky and use regular fuel ...
