my shock absorbers after 4000miles are completely soft No visible oil leaks So I think of a gas leak Has somebody refill air in ?How ? According to the workshop manual, a needle is needed and then with a air  compressor it's necessary to put 7 bars so....?

Looks like a needle for a basketball.

I would take care.

Shock absorbers being so small could be very easy to damage almost insantly if overinflated.

At the very least use a compressor with a good regulator set to the maximum the shock can handle.

     This is standard stuff on dirt bikes. Most use a Shrader valve like an inner tube, but some do use a needle. Try a KTM dealer. It must be PRECISELY charged or you will blow out the seals. They will recharge it with nitrogen because nitrogen is inert. Oxygen is not inert and can be explosive under certain conditions. It may blow out your seals under a high stress situation. This is a real low percentage on an Enfield, but it has happened.
     The needle must be lubed for insertation or it may tear or dislodge the rubber plug.

thanks to you all ,guys!
I think 'I'll use a basket ball needle as JVS told me And anyway if I kill them by overinflation it won't be a big loss as I think they are a real bullshit !My dealer ,as the bike is still on guaranty told me it was my fault as I often ride with my wife!!!! My previous 300cc 1990 MZ had 90.000miles ,never changed the absorbers .OK ,I don'expect the same from the Bullet but 4000miles.....!
Thanks Greg for your offer but I live in France,It's a bit far from Nevada !
