My SAABs were all this way, but my Land Rover is not. All my friends were impressed when I told them it took 5 minutes to install a new fuel pump in my old SAAB 900. They were even more impressed when I told them I changed the clutch in that car in 30 minutes; now there's some engineering. If only the Europeans could get their electrical systems to be less quirky... Mark

I ran all this by a friend with an R1150GS. It took him a half-hour to change the fuel filter the first time, without removing the tank from the bike. He said it was a little tricky, but not brain surgery. If they'll let me, I'll take a peek inside the F800GS tank in at the Long Beach show and see if it's accessible. __Arden

E.L. Green asked: "Did anybody make it out to San Mateo yesterday to see if the 800GS was out there? Not that I'm interested in it, it doesn't haul enough fuel (the gas tank is under the seat just like the F650GS), but I was busy changing tires yesterday and didn't make it up there to ogle the new bikes..." Yes, I was there. In fact I purchased a 3-day pass (only $7 more than a single ticket) and went all three days. People were all over the F800GS, which won't be at dealers until March '08. Very nice looking bike, no heavier than the KLR and almost twice the power. It also costs twice as much... The fuel tank size is a problem for me, along with the price, but perhaps not a show-stopper. Available in a subdued but attractive flat gray and black (at the show) and also will be available in yellow and black. At the Kawasaki display you could see KLRs in all three colors side by side. The red one had the Kawasaki factory top case, tank bag, and throw over bags. IMHO the tank bag and side bags are too small, but the top case looks useful. The tank bag could serve as a map holder and maybe for sunglasses and extra gloves. Everytime I went by the KLR area there were people there checking out the bikes and trying them on for size - mostly, ah, gentlemen of a certain age like myself. OTH at the BMW area a few younger folks were checking out the F800GS. One young guy who said he has a 600cc sport bike wanted to know what a parallel twin sounds like and how fast I thought it was. It was time well spent, even if I'm not in the market right now.
