Air Compressor

Postby jjunkin1 » Wed Oct 29, 2014 9:53 pm



I didn't see this one asked yet so I will try yall out. I recently acquired my first wing. It is a 81 1100. The PO removed the air compressor so I am adjusting air manually. Spring are shot and she bottoms out constantly. I am trying to decide which progressives to go with. Since I am adjusting air manually anyway should I go with the 412's. Both shocks are currently linked together so all adjustments are done from one place. Are the 412's linked or will they have to be adjusted independently?

This site is a great help! Already rebuilt starter and front and rear master cylinders. Never would have done it with out this side.

Thanks for advice and opinions.

Progressive 412 shocks are spring only, no air. I believe the 416 are air shocks. Personally I replaced the stock air/spring shocks on a GL1500 with 412's and am very happy with the choice.

Correct. I replaced the rear shocks on my GL1100 with 416's, connecting them to the original compressor system. I liked them so much that I did the same thing on my GL1500.

Thanks for the reply. How stiff/forgiving are the 412s. I am about 250 lbs and my wife is 140ish. She rides with me about half of the time.

I bought the heavy duty 412's as I have a sidecar on the GL1500. Our weight is about the same, 250. Feel more planted on the road, but then the original shocks were old and worn.

Since the GL1500 is a 20 year old bike, was concerned the air compressor or its fittings might fail, leaving me with expensive 416 air shocks that don't work. Sometime simpler is better.

Thanks Guys. My front seems fine is there any problem yall are aware of just doing the rear? Since I have no compressor anyway I believe I will just go with the 412s. Look forward to the "winter" project. Here in Mississippi we have plenty of riding weather even in the winter.

jj,
Do just the rear, ride and then decide if the front need attention. Installing the 412's is easy to do yourself, no special tools required.

Let us know what you think of them.

Last question I hope. What is the proper length 412 for the 81. I see prices ranging from 188 to over 300 bucks and lengths from 10" to 14 1/2". Can't wait to ride without slamming on every crack in the road.

The 412-4223C fits the 1988-2000 Goldwings. Bought from Cycle.com for $224.96 with free shipping. Shop eBay for the best current price.
