Thanks man.Hey Eric. I have the part you need. Unless you are dead set on a new cap. All you need to remedy your situation is the plastic threaded part. Let me know if you want it.
2006 Daytec frame - Tried 2 caps, both were flush mount, then push to pop out and spin entire cap out - If you turn cap about half way out, you can wiggle it and feel it is loose in the threads... cheap cap made of plastic.Lambo-odd, I removed the paint savers from my tank last year and fitted stock HD caps and they seem to fit perfectly, no problems here whatsoever. Not sure about the year of your K9, I have an '04 Mastiff.
Erik-If you can sort this out, my recommendation is the HD caps, they work (at least on my bike) flawlessly, and the price is reasonable.
