If you have the length, a 7317 size filter will fit (same diameter, just a little longer), as will a 9688 (longer and slightly wider) and a 3593a (a little longer than the 9688).
I found the 3593a size to be almost identical to the Honda oil filter.
Thanks, that's good to know. I'll measure around the filter to see how much clearance I have...
Thanks to all for the M7 comments. It's for the front, so won't be pushed very hard.
With my wife on the back, this is bike is heavily biased towards the rear tire. So I want some extra bite on the front. I'd hate to wash out the front, then have it bite, and high side us (been there, done that, oil slick...). I used to run R compound Dunlop's on the front and S compound on the rear (other bikes). But the Pacific Coast has odd tire sizes, so looking at what will fit ... M7 is available
