I picked up a set of JIS drivers off amazon for like $15. I picked up a 2009 a couple months ago and did full fluid change and belt change and swapped out some roller weights while had the cvt apart. It took a couple evenings and half a Sunday to get it all done (there was tire change in there too). I highly recommend lightening your roller weights, it made a huge difference for low end acceleration.jggimi said:It's been sitting for a decade. I'd not only change fluids, I'd consider replacing all rubber components: tires first, but also consider replacing all vacuum and brake lines. The Maj has an air cooled belt-drive CVT and dry clutch, so there's no transmission fluid to change.
There are 3 air filters: 2 for the engine -- 1 on each side of the bike -- and an air filter for the CVT. The engine filters will likely need to be replaced more frequently than Yamaha recommends. The filter housings are attached with JIS screws. JIS looks like Philips but isn't Philips. If you don't use a JIS screwdriver you *will* strip them, and if you use a JIS screwdriver you still risk stripping them. Use a long JIS screwdriver, lots of penetrating oil, and even more patience than you think will be necessary.
