Being the brand-spanking-new owner of a '09 DR650SE and being an newbie motorcycle owner... Upgrading the gas tank for longer trips seems worthwhile. In reading the forums the IMS aftermarket tank seems popular. The Corbin seat also, from what I've heard, is a good upgrade for longer distance riding. (Like getting to the Olympic Peninsula from my home on the other side of Puget Sound) A couple of questions I have. Having never worked on a motorcycle before, it seems like the seat replacement is probably within my capabilities and won't get me in over my head. If I were to choose to replace the gas tank is that within a newbie capability? Also - anyone know if that will void my warranty if I do it? Thanks!
