do NOT settle for crappy oil filters.
OIL FILTERS EXPOSED! - Yamaha OEM
Yamaha oil filters are crappy from what I've seen. ACDELCO or K&N or AMSOIL top my list of filters.
as far as oil, if you have a walmart nearby, go grab some Shell Rotella T6 synthetic... its made for motorcycles (it just doesn't have the picture of a motorcycle on the outside of the bottle.) SMOOOOOOOOTH shifting.
Shell Rotella T - Wikipedia, the free encyclopedia
"Though marketed as an engine oil for diesel trucks, Rotella oil has found popularity with motorcyclists as well. The lack of "friction modifiers" in Rotella means they do not interfere with wet clutch operations. (This is called a "shared sump" design, which is unlike automobiles which maintain separate oil reservoirs - one for the engine and one for the transmission). Used oil analysis (UOA) reports on BobIsTheOilGuy.com have shown wear metals levels comparable to oils marketed as motorcycle-specific.
JASO-MAJASO is an acronym that stands for "The Japanese Automotive Standards Organization." Among other things, they set standards for oil to be used in motorcycles.
Shell Rotella T 15W-40 conventional oil now lists on its packaging JASO MA as one of the specifications it meets, as does the Rotella website product page:
Note that the 10W-30 conventional oil does not list JASO-MA.
The newer fully synthetic T6 5W-40 oil also lists JASO-MA compliance on its packaging and on the Rotella website."
K&N FILTER CUT OPEN:
The nut on the can allows for easy removal and is drilled for safety wire! For the space constrained, the nut can be a blessing or a curse. You won't need to contort yourself to get a filter wrench on it, but if you are already short on clearance to your pipes or other obstructions, fugeddaboudit. The nut adds about 3/8th's of an inch to the overall length. The bypass valve is sealed with a rubber gasket. The mouting gasket is semi-O-ring. The filter element itself is dyed K & N's signature red color.
YAMAHA FILTER CUT OPEN:
This Denso-made filter has
paper endcaps! The bypass valve, shown on top of the filter element in the photo, is
glued in place. The filter element itself is very strange, with the pleats opening concentrically into radial channels, as opposed to facing the circumference as most filters. The element itself is so large that it was almost difficult to get out of the can. This filter shares common cross-references with Honda.
