Gas, electric, diesel, pedal power, solar power, no problem. As long as it has two wheels post up a pic of what you ride. (<edit> . . .Trikes OK too.</edit>) I started about 1969 & this is my 7th bike. It's a 2004 Kawasaki Nomad 1500. Fuel injected, overhead cams, and water cooled, with a spicer type driveshaft. They call it the Slow-nad because it's so porky, top speed in the 1/4 mile is only about 88 MPH. It weighs way over 800 lbs wet. Here it's very wet. I just rode it over Tioga in a thunderstorm. 10,000 ft elevation at the pass. But on the road it'll do 100 MPH as long as you want to hold the throttle, or for about 200 miles, where it runs out of gas. These bikes have one weak spot. There's a bearing in the bevel gear box that wears out if you hot-rod too much. Mine started to go at about 56,000 39,000 miles. The dang thing only cost $24 but it costs $2000+ to have a dealer change it, because it's a pain to set up the preload and tooth contact, you have to remove a lot of parts, and the book actually says to take the whole engine out. I didn't. I've done a few differentials in my life, so I knew how to set it up, and only had to make a stand for the bike that would allow me to take the engine loose in the frame and move it sideways a little, then I didn't have to actually remove it. Otherwise, these motors have a reputation for going over 200,000 miles, and the issues people have with them are mostly related to drag racing (It has "highway" gears in it) and lack of maintenance. Here it is torn apart for the new bearing. BTW I held a contest at MC USA to name this bike, and the winner was Baggins The Nomad.
