Maybe a silly air ride question

Post by bow61509 » Mon Aug 06, 2018 9:52 am



So I recently purchased a 1988 gl1500, this may be a silly question about the air assist. I read that it shouldn't exceed a certain pressure in the rear shock, maybe like 50 something psi or something similar (the exact number is on the sticker, and I'm not near it lol). That being said I also read you are supposed to check the pressure and adjust it while unloaded on the center stand. So, is the pressure that shouldn't be exceeded while it's on the stand or while it's loaded with weight. Let's say I set it to 30 psi on the stand, once it's on it own weight and a rider is added it may show in the 50's add a passenger and now we could be showing even more pressure. So, keep the pressure low enough to where loaded and with gear and passenger never exceeds the psi on the sticker, or just don't go over that pressure while on its stand and don't pay much mind with the loaded reading?

Max pressure unloaded.Ignore the rest.
I ride two up at 40 psi.Adjust as needed but don't exceed the Max unload pressure.

If it says to only check it with no load, while on the center stand I’m going to go out on a limb and say that it is a bit like tire pressure and it is at that time that 50 psi should not be exceeded.

Kinda like checking tire pressure when they’re cold. It will increase as we ride, but we don’t lower the pressure so that it will not exceed the recommended pressure when they do heat up.

I hope I’m not wrong on this one.

It's not so much heat as it's pre load pressure +the bikes weight+maximum bike load capacity+maximum shock compression (hitting a bump) that's been calculated into the shock design to handle the pressure so it won't blow the seal.
I can't imagine , if maxed out what the pressure could spike to.Hunderds of pounds???

Set with the wheel up to within specs ...like the book says..I guess you could drop it down and check again to see if it changed much and then be able to set w/o putting it on the center stand..
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,

Thanks guys! I figured it was the max pressure while unloaded, but just wanted to confirm. As far as the changes in pressure when on the stand and say when I'm sitting on it and the shock is handling the load it's a pretty substantial difference. I think currently it's around 30 psi unloaded and sitting on it shows like 42 psi. that's where my question stemmed from. Loaded 2 up 50ish psi is only like 20 something psi when on the stand, and very very soft. If that makes sense.

Unloaded max pressure is 57psi by the manual. That can push the 2 up loaded pressure up into the 70 psi range. Don't go by the loaded psi.
