I am in the middle of changing the oil on my 2000 v-star. The current filter is a kn-145, but per the cross referencing research I did, a fram ch6004 will also work. The problem is the fram filter seems to be a tad larger then the kn. The kn fits in nicely and the oil cover fits neatly over top. When I put the fram filter in, it hangs out a fraction of a inch which makes putting the oil cover back on rather challenging. Put another away, the oil cover doesn't slide neatly into place over top of the fram as it does with the kn. Advice?
