Another plea for advice/information, this time about Monsters. I may be able to acquire a Monster S4R for money I can afford. It has an oil leak from a cylinder base gasket, and the starter doesn’t work, I’m told. Are either of these complex jobs, do they necessitate engine out? I’m happy enough to do the work myself if possible. 2003,10K miles, 3 hours away. Some service history, no info on belts yet.
