I'm not a fan of pressure washers as it'll drive water past seals and into
bearings etc.
The two best products I've found are: S100 and even better is ProClean
Concentrated bike cleaner, I had to order that online. Remove what you
can with a plastic scraper, and spray this stuff on and let it set for 5 min.
hose off, might take a second shot.

Guns will blow a hole in yer foot, too. KInda gotta pay attention to where its pointed. Study the bike, decide before you even get on it where you will need to put the direct spray to get the results you need w/o messing things up. Costs about a buck for a few minutes of High Pressure. You can spend that dollar & knock a ton of crap off the thing in places far from any bearings & seals. There will be plenty of detail work, places you really really shouldnt blast water at. No, pressure washers & motorcycles arent a perfect mix. Idiots shouldnt use a pressure washer on their bike. Anyone with the mechanical understanding required to keep one of these running & give them the benefit of a warning should be okay..
