Honda, Kawi and Yamaha oil filters all have the same thread size 20 X 1.5 mm.
According to another website that I don`t recall at this time, Suzuki uses a proprietary thread size that only fits filters they sell. There is no high performance filter available to fit that thread. There is an adapter plate available somewhere to convert a Suzi to the same filters the other Big Three Japanese bikes use.
Here is a little more info on the vn750 oil filter and mounting plate.
- '85-'94 = larger size 2.95" diameter
- '95 up = smaller size 2.76" diameter
Oil filter (mating) plate
- '85-'93 = 13169-1921 = 2.95" (75mm)
- '94 = 13169-1921 = 2.95" (75mm)
- '94 = 13270-1170 = 2.76" (70mm)
- '95 up = 13270-1170 = 2.76" (70mm)
I went to change the oil on my bike (1989 VN750) last weekend and noticed that the filter I got at the local dealer (Kawasaki filter) seemed to be smaller in diameter than the one that was already on the bike. I brought the one that I took off the bike in with me, along with the one they had given me, and asked the guys at the part counter if maybe they had given me the wrong one.
They said that the one I brought in - the one that was on it when I bought it - looked way too big, and that it appeared to be from a Mule or something. I asked them if they were positive that the one they had given me was ok to use, and they said it was.
I think most Kawi dealers are looking for ways to cut down on the cost of parts inventory, so only stock the superseding part if possible. Because the smaller filter will fit and work on more/most/all(?) Kawi bikes, even if it is not the most efficient, that is the one they stock. IMHO.
I thought I read sometime ago that the larger diameter filters would still fit on the smaller mounting plates of the `94/`95 and later models.
That doesn`t make sense to me, but can anyone confirm or deny this perception?
