Hey Grab.......I didn't mean to imply the charts were yours. Sorry if I offended you 'cause I sure didn't mean to. Also, as I reread my post I realize that I should have elaborated more on the size/emissions point, but then again I could have elaboarted more on a lot of other crap, but the point's still the same. One thing you brought up which relates to all cars, is the short trip factor.

Short trips are tough on any car for a lot of reasons I won't go into, but from an emissions standpoint, they're a disaster. Without going into details, an engine needs entirely different "settings" to run cold and these are all higher in tailpipe pollution, FAR higher, than hot engine specs. And if you're driving a Super Belchfire SUV you are tossing out a LOT more under these conditions than a 1.5 liter Econobox. You see a difference at warm ops, but the difference in cold start is much higher. The manufacturers would pull them out of cold settings way too fast (for the engine) to get them through the EPA driving loop because of that. Again the computers have eased the load on the engine a good bit and allowed a little cleaner cold operation with better driveability, but the emissions are still FAR higher cold than hot. Bikes are nice.

On the CO thing.......We used to solder fuel tanks on the car with gas in them by "inerting" the tank with CO. We'd hook up a tailpipe hose to the fuel tank filler using an older car which produced more CO and run it for a half hour and then crank up the torch. This was a great way to get rid of "hangers 'round" in the shop. They'd asked what we were doing and when they found out we were about to stick a torch around a gas tank with gas in it, they'd suddenly remember they had to be elsewhere.(:<))
