Remove 1983 GL1100A Air Compressor for Good!

Postby Admailwiz » Mon Jul 08, 2013 9:09 am



I searched and did not find this topic directly covered with the usual clear simple instructions &/or Tips!

I want to permanently remove the non-functioning & heavy stock air compressor on my 1983 Aspencade restoration.

My Questions & "Techie Issues" are as follows:

1- I aired up the front shocks to top of their range & rear shocks to middle of their PSI range with an effective, lightweight, portable Harbor Freight air compressor hooked to the Honda compressor air fitting before I removed it. The air went to both shocks via the selector button. Does the air distributor between front & rear remain after I remove stock compressor?

2- Both the front & rear shocks held their air pressure readings fine for about a month after removing the stock compressor. Is this "Normal;" or am I in danger of the air getting out & needing to air up without a compressor on a long road trip?

3- The small hose that remains in the false tank after removing the Honda air compressor has some strange non-standard fitting wit NO air valve in it! Is there some way I can attach an air valve to that hose and use that to easily air up my shocks?

4- Or is there some much easier and elegant way to achieve my objective of touring without the useless & heavy stock Honda air compressor and yet have an easy way to air-up the shocks if I need to on the road?

I need any great "How-To's" or Technical Tips from members who may have tackled these issues before or have any advice!

I got rid of the compressor, replaced the rear shocks with Progressive spring/shocks and replaced the fittings on the front shocks with standard valves. I now carrry a small bicycle hand pump with a guage in my bag. Works well with no danger of over pressurizing the front shocks [done it, can't recommend it]. Bike handling is much improved with the new rear shocks even if the bike sits a bit higher.

roadwanderer, Progressive rear shocks #416-1622a will be a perfect fit for your Aspy.They come with a "T" Schrader valve fitting that when installed you can mount behind one of the side covers. If you want to hook to your compressor in the future you'll need kit #30-5082. Hope this helps.

Replacement rear shocks are NOT air filled. Progressive 412's. Shop around big price variations. I adjusted them to the middle range seems OK if a bit stiff.

ok, I know this posting is a little old, but here's what I did to a set of stock rear air shocks. I took them off the bike, took the stock airlines off, took a NPT18 tap and retapped the holes, went to my local parts store and bought 2 NPT 18 air Schrader valves, took some liquid Teflon sealer, gave the inlet side of the valves a good coating and screwed the valves into the shocks as far as they would go. now I can put air into each one individually. only draw back to this is I have to take the seat off every time I need to put air in them. as for my next "project" im taking a pair of progressive 416's and having them rebuilt with new inner springs and seals so I can get a "T" connector and mount the air inlet connector inside my trunk so instead of taking the seat off every time I need to fill the shocks, all I have to do is open the trunk and fill 'er up.....................bikerbuck, that's the shocks I have now. the 416's.

rcaron312, I did the same thing you did by removing the stock onboard compressor, but I took it a step farther. I went to my local junk yard, found an old cb900 with front air forks, took the fork caps off of that bike and the caps off from my forks, rerouted the front fork air line, installed both fork caps from the cb900, and I can now put air into both forks thru one line, and while I had the caps off, I drained and refilled the forks with fresh oil. same exact set up as on the GL500 silverwing interstate except the air inlet valve on mine is on the left side as the one on the silverwing is on the right side, then all you need to do is tuck the line inbetween the upper triple tree and under the control pad.

if anyone's interested, I have a brand new pair of heavy duty rear coil over shocks with 5 tension settings that will fit on an '80-'83 g/w gl 1100, std, inter, and aspy. I bought them for my bike, but they are too hard. I don't have enough weight on the back to use them, so I took them off after about 50 miles and put my air's back on. if anyone wants to purchase them, they cost ME $160.00 last month, im willing to sell them for $120.00 plus shipping. also for sale is a brand NEW, not used OR recovered travelcade double saddle seat. I like it, but my wife says its not comfortable for her, so im selling that too for only $130.00 plus shipping. you guys know how much these travelcade seats go for new, (well over $200.00), so I think my price is fair. attached to this posting are pics of the shocks and the seat. judge for yourself. I have other parts for sale in the classified section just in case your interested.

Hi, I'd be interested in the seat but the shipping to Ireland might make it too expensive. Would you mind checking the price for me?
Thanks!
