Burchdog,

Here we go again!
I would go with a gas unit, (electrics are fine when they work but fail more) PSI wise, 1800-2400 is an average size for what yor doing, and work well. Keep in mind if you get a litlle bigger unit you can use it for much more, (driveway, car, house, paint chipping, etc etc) when you use a larger unit on the bike , just idle it down and use it at a lower speed. (save the bearings and seals) Also, most pressure washers are not gravity fed. You need an adequate supply of water (2400 psi at 2.4 gallons per minute, you need at least a 2.4 gallon per minute supply of water!) You can put a shrader valve in the cap of your water supply and give it about 10 psi and that should work. All that said, I use a gravity feed tank at the races, keeping the tank in my pick up, and running the engine slow or at idle (2400 psi unit) and it works fine. Once in a while I have to blow some air into the tank to get it going, once it starts it usually stays working.. Brands, Sears (craftsman)- Lowes, under the Troybuilt, Husqavarna and Lowes/Generac Portable Product brand names for a few. These are all made by Briggs and Stratton Power Products in Wisconsin..... where I work supporting P/W and Generators. If you need any more info, drop me an email and I can give you a call! :thumb:
