Cutaway of oil filter – no check valve

I'm David Petersen, owner of BestRest Products. You can see my photo on the home page. I've been riding motorcycles for almost 60 years, and during that time I've had some wonderful adventure. In 2000 I started BestRest Products - our first product was a folding back rest, hence the name of the company. Over the years I kept designing and inventing gear. Today we have over 300 products in our store, and I created many of them. I ride a BMW R1200GS, a BMW F800GS, a Honda XR650R, and two KTM 450-EXCs. Plus I have a couple quads that I keep at a summer cabin. I spend most of my free time riding with my wife Judy. When not riding I'm answering the phones at BestRest or working in the shop on some project. I'm also the author of "How To Ride A Motorcycle Off Road", which is a free book you can download from the website.
