I just got the Kawasaki Motorcycle Service Manual for the Vulcan 900 Classic/LT (p/n 99924-1366-10). Well worth the extra bucks to get this IMHO. I've purchased a Haynes manual for another bike and was really disappointed in the quality and completeness of the content. I've also looked at the free online version of the Vulcan 900 manual but that just wasn't handy as a reference. This OEM manual has more information than I will ever want to get into, but for someone like me who is not necessarily a gear head but wants to know his way around the bike, this fits the ticket.
