Just an old, bald man!
Don't do it!I am considering a tire patch kit with CO2 cartridges instead.
Just put a 15 Amp fuse on your battery tender connector and an SAE connector on your pump. 15 Amps is enough even for the more powerful tire inflators.
You will be surprised at how many CO2 cartridges it takes to inflate the rear tire of an FJR, to rideable pressure.
