Gas filled Shocks

  • I own an Electra 2004 4S, the very first of its kind. Bought on the 1st Oct, 2003 and it had come with gas filled shock absorbers. I just wanted to know, how do we maintain it or is there a difference between the normal one and the gas filled ones coz i did not feel any..

  • When they say "gas filled" it means the shocks have a gas charge (usually nitrogen) on top of the oil in them. Nitrogen, sealed in the shock, does not absorb moisture and is more stable than air. No maintenence is really needed, treat them like an ordinary shock, but don't try to take them apart, the nitrogen is under pressure.

  • Hi,
    I have Bullet 350 Std. Can I fit gas filled Shocks on it, Do I need to do any modification ( any kind of welding ) to get it fixed. and how is the performance.

    No weldings needed, compare the shock you want to put on with the original, the mounting holes should be the same diameter and width and the length should be awfully close to the original, maybe a little longer if the shocks are older and have sag in them. Mount one and have a friend, preferably a large one, bounce up and down in the saddle as you observe the travel of the shock. It shouldn't hit or rub on anything. Thank your friend.

  • Hi,
    I have a Bullet 500 (purchased in Jan 2004). I have fitted the RE Gas shock absorbers almost an year back. For the first 2-3 months the rides were better. However after that my wife started complaining of backpain. Everytime i ask the dealer on how to fix this problem, he just tigtens the spring on the shock absorber. Now with the gas shocks at full tight (last adjustment position) and problem became very serious. I cant take a pillion rider for even 10kms and they complain of server back pain. However when i ride some other 100cc bikes i or my wife dont feel the stress and pain.

    Can anybody please let me know, what might be the problem and how i should get it fixed? do i need to buy new Shock absorbers?

    Thanks in advance.

    One of three things has happened. 1. Shocks don't last forever, especially carrying passengers, and yours may be shot. Remove them and try to compress them, compare them with a new shock. 2. Your swing arm bushing is in need of lubrication. Put the bike on it's center stand, remove both shocks, try and lift the swing arm up and down. It should move freely. 3. A little of both of these problems.

    Ever time the dealer tightens up your shock springs it WILL make it ride harder. Maybe they should....I don't know...try loosening them up.

    hi Srini
    I have also gone for gas shcok for A350 three months back.Recenlty i felt that shocks have become hard and doesnt have the same ride which it was giving me before. The action in the shocks are not complete, means, the shocks doesnt come completely back on its own once it is pressed down, resulting in harder forces coming back to the frame. This could be the reason for your problem. Frankly speaking this happens when your shocks are out but i don no why it is happening so early in my case also.

    Coming to your point, What you are doing is basically making shocks more stiff and there by your bike has become uncomfortable even for a small distance ride. Whereas, i have done the otherway, i have made it less stiff so that it has more action and there by absorbing much of road shocks.Iam keeping the shockz in its lowest possible stiffness position and i find it much much better than before, you can also try this.

    Regarding the retrofitment, yes, the gas shocks are longer there by your chain gets tightened. You can feel this, by putting your vehicle in neutral while driving, if you feel the vehicle is not rolling freely then it means that the chain is overtight and needs adjustment.
    Second thing to be taken care while retrofitment which i have observed in A350, the bracket which is holding the silencer (bent shaped) fouls with the swing arm beacuse of the increased length. This may not be applicable for other models as i dont know which bracket is used for other models. The reason being the bent given in the bracket is not sufficient for providing enough clearance.

  • Hi dear,
    Recently I changed the rear suspension to a gas fitted. I don't feel much difference in comfort but obviously money.
    I think instead of buying gas suspension, you can replace the stock susp every two years. Moreover while fixing the gas susp, they cut the susp upperend clamp connected to chassis. This is quiet dangerous.
    So my suggestion is if you are not equipped with gas susp, then buy new normal oil susp.

  • I have bought aTB 5 mnths back. Then at the rear there was no Gas filled Soccer. I felt problem with it, when I took a pillon. Now the the company is giving Gas filled in the new ones. Will I get a replacement from the company?? What will be the cost of 2 if I purchase them.

    My 80 model is scheduled to undergo gas filled sus modification,It cost around 1800/- for rear shocks in tvm. May be less in ur place.

  • The gas in these shock absorbers basically has two functions:
    a) To increase the resistance of fluid flow into the reserve tube. What this does is improves the performance during the beginning of the rebound stroke of the spring.
    b) Another function is to minimise aeration of the shock absorbers hydraulic fluid. The pressure of the nitrogen gas prevents air bubbles or foam from weakening the hydraulic pressure of the fluid flow through both the piston and the base valve. Foam or air bubbles are not good for performance because they compress and fluids do not. The technical term for this is cavitation.
    Gas absorbers are good and if fitted well can really improve riding comfort. Whenever you do a service at a dealership ask them to measure the system pressure of the shock absorber in front of you. If it is less than 5 BAR then it needs to be recharged. When recharging your gas shock absorber, the tolerance for filling pressure should be in between 6.7 BAR to 7 BAR. FYI, 1 BAR = 14.50 psi. That is very high pressure, so that is why Brian mentioned below not to take it apart on your own. It could be very dangerous. Charging costs money so don't feel cheated when you are asked to pay for this. Hope this was useful. Ride Safe guys.
