No way would I use a gas powered leaf blower on my bike, period...I purchased the long handled air device that some of us got a while back from Harbor Freight and hook it up to my air compressor if I need it...Have never washed any of my bikes with water anyhow and only clean with Honda Cleaner/polish..(now called Original cleaner/polish)...Been lucky I suppose to have not gotten on dirt roads or in the rain when riding.....Ride safe
Several years ago, my dealers washed bikes after a service or repair. They used pressurized air to dry them off This became an issue, as it forced water into connectors and there it would slowly corrode and begin a host of electrical issues. Many dealers stopped due to customer issues and arguments about the air pressure and the issues they found it caused. I get this info from my brother who owns Harley Dealership in Connecticut. They found some mold and/or corrosion and with electronics not using high amps, there in lies the problems!
