Theses are our first bikes and so far we have been having a blast learning and will soon be taking a saftey course. Since I have no idea when the oil was last changed on the bikes I figure that will be a good start to doing maintenance on them. From what I can find online the filters are the same for both bikes ? Looking for a good online source for the filters since we dont have any local Suzuki dealers. Also what is the recomended oil?
Oil filters should be the same for both bikes. If you like the idea of doing your own work on the bikes, get to know the Tech section of this forum. One of the first threads there is a table of contents for the tech section and will include all your maintenance (and mods and fixes) for the bike, including oil changes.
People around here are very touchy about what oils to use, but in the end it is up to you, so use what works. if you are planning on riding in colder environments, a lighter weight oil might help you out (as well as an iridium spark plug), otherwise i'm fairly confident that most oils will work just fine.
Hope you and your lady have a blast riding, these are great bikes with a lot more to them than they look. Now that you're part of the club, don't be shy 'round the forum!
