6. What about filters?
For 85-95 bikes, you take a cartridge style filter, and don't have a ton of choices. Fram CH6002, OEM Yamaha, or a generic aftermarket.
For 96-07 bikes, you take a spin-on style, and have loads of choices. Fram PH6017, Purolator ML16817, NAPA Gold 1358 are all MC-specific filters
If you want "the best", get a top-shelf filter and reference a '94 Mazda MX-3 with the V6 engine. It will fit with no problems. Mobil 1 M1-110, Bosch 3323, Purolator PureOne PL14610. PureONE's are yellow though.
Stick a couple small puck magnets to the outside of the filter, if you cut it open when you change you'll see a big glob of nasty collected on top of where the magnet was. You can get a pack of these at any hardware store for like a dollar.
