The 1800 must have a compressor to fill the rear air shock--right? So, how can I use it to check and fill my tires?
Mine rides in my left saddlebag with the tire plugs, tools, first aid kit, etc.
:agree:I carry all of that stuff in one saddlebag too, but I prefer to put heavy stuff, including extra water, in the right saddlebag because when the bike is parked on the kickstand the contents of the left saddlebag put a lot of pressure on the latch. It takes a lot less pull on the saddlebag lever to open the right saddlebag and it also reduces the risk of bending or breaking the mechanism.
As noted, you can't.
my GL1100 had a compressor for BOTH front and back shocks, as well as an aux. port for filling tires, or beach toys or ...You are thinking the 1500, and it only was the front end that you could fill with air.
