Dahon Jetstream EX - suspension question (any owners out there)?

Hi All ,

Have recently purchased a 2010/2011 new Jetstream EX and have a question about the suspension, specifically the valves.

When pumping them up lots of air escapes and basically they revert to no pressure. I realise air escaping can be a common thing on all suspension, but after taking it to my local bike shop for a setup/service it seems the ends of the valves protrude out much more that you would expect and they do tend to release a lot more air.

The LBS did pump up to max and even with air escaping itís more or less ok now, but I was wondering if any other EX owners can confirm if they have had the same issue and how they resolved. Eg, did you live with it or maybe change the valves to something else (assuming this is possible).

Any help/advice much appreciated, thanks

A good shock pump will have a bleed valve. You overpressurise *slightly* and then bleed to your required reading. As you unscrew the schrader fitting the valve closes first - then the hiss you hear is the pressurised air escaping from the pump delivery hose. Ignore it.
