I own two k5s and have owned a third at one time and i think on all thee i have lost a swing arm nut at least once during rides. I also ride with a bunch of k5 riders and have noticed their missing nut at one time or another. I was wondering is this common with the k5ers on this page and if so has anyone come up with a good fix idea. Wire tie, drill and pin it or anything else. I always loctight blue it and tighten it good, but open for suggestions or heck tell me what i might be doing wrong.
