Lefty Carbon Issue Pumping Air Hard Time

[Ginbraiba]

Hi.
I have a Lefty Carbon SL OPI from 2009 bought in second hand as new in 2010, and the only issue since then is that when i try to pump air on it it doesn´t let me, or i have to force it a lot. First i tought it was the pump that was malfunctioning but pumping on other suspensions it works great.
At first visit to the lbs i reported that problem to the mechanic and he said probably it was the lefty valve. He changed it. But it didn´t work.

Anyone has any insights? The lefty works great tho, but i can´t pump air so easly and never know the pressure i´m riding.
It went to 3 revision alredy and never resolved this issue
thanks

Some of those valve pins can be kinda deep. Certain pumps won't reach it. Either try a different pump, or, use a small ball bearing in the pump head to act as a actuation pin "extender". Just be careful to only screw on the pump till it registers pressure, as continuing to screw it on could crush the valve....
