Rubline If you have a small portable compressor, you can set the air pressure knob on the compressor for 25 lbs. When you fill the shocks, the max pressure you will get is 25 lbs, thats what i did

2fas4u I weigh about 160-165 and run mine on #2 most of the time. #3 with a passenger. I only use the #1 setting, which is soft, on long trips with flat roads and no baggage.

Great info! Been wondering how to handle this since:
A - I'm 250lbs and the suspension needs to be working well to handle that!
B - Using a hand gauge changes the pressure!!

So, I just ordered a 0-100 lb Progressive unit from Dennis Kirk for $53 including shipping.

This board is an incredibly useful site for learning the 'how -to' stuff for our bikes! Thanks to all who contribute.

lancer19 Progressive Suspension makes a hand pump with a gauge installed (GP2 Guage Pump. Model GP2-0-60). Not sure how much it goes for. I borrowed one from a friend of mine. The manual only has a chart going up to 43 PSI, but a note later on states to not exceed 71 PSI since it could damage the oil seal. I don't think I'd go over 43 PSI.

curtis97322 ohh... forgot to add that part <g> glad ya caught it theauhawk - the air bladder in the shocks is tiny and takes a tiny bit of air. Using an unregulated powered air source will blow the bladder real quick.


What I did - but don't necessarily recommend - is set the regulator on my air compressor to the pressure I wanted - check same pressure with a known good gauge - turn off the compressor just in case - and add air. Definitely taking a risk should both gauges fail - but It worked and pressure was what I wanted it to be when I checked... keep in mind that checking pressure causes the shocks to loose pressure.

The other option - and probably the safest - is to use a hand pump. Should be less than 10 pumps per side - seems like it was around 5 pumps on my tiny bike pump (the type ya carry on the bicycle).

theauhawk Correct me if I'm wrong on this someone, but to add air pressure to the rear shocks, it's best to use something like a bicycle tire pump or some sort of hand pump only.

Using any sort of powered air pump will quickly overfill the rear shocks, and damage the seals--they simply don't take much air.

As with the tires, check the pressure in the shocks when they are "cold".

Even the owner's manual says to inject air in the shocks slowly....

curtis97322 air valve stiffens the ride. Rule of thumb is to have 10% of the total weight of rider and passenger in the shocks if you are above 150 lbs.

I.E. I'm around 250 lbs - so I run around 25 ft lbs of air pressure.

The numbers adjust the rebound - seems like there's something in the verses (I'm having a brain fart)

Rear Shocks Adjust?

OK, I'm showing how little I know about my bike. But if I don't ask I'll never learn. How do the rear shocks work, AKA Adjust. I see the numbers, the air valve so whats the deal. Does it stiffen and soften the ride? I'm lov'n the bike but I deffinetly need to know more. Thanks.
