No, Joe & W14 (not W114 perhaps? :oops: ),
Pulling the extension mast is not a good idea in order to exchange it.
If you cant't get it retracting and coming out completely anymore by greasing you also might want to try with a little WD-40. Sometimes that helps.
Is you mast bent? If it is a little bit, it sometimes helps to try to bend it backwards. But carefully please.
If you want to take out/exchange the mast you need to take out the whole power antenna assembly first. This can be accessed either via the removed kickpanel or you need to take out this metal piece/flap/door which goes behind the front wheel house and covers the area where the power antenna sits.
Then you have to disassemble the whole antenna. Check for your type and try to find replacement parts either at Becker of North America (Ed Ebel in New Jersey) or Rainer Königs in Ratingen-Tiefenbroich, Germany or the like. I would first buy a new replacement mast before you 'destroy' the old one.
Exchanging the mast can be tricky but it is worth it. The older (and more original) the power antenna, the more worth is the trial.
Mine was an Auta 6000 F108 but I believe there are older types original for our Pagodas too.
Unfortunately, not many sources do know exactly about this.
The antenna which is visible in the link Naj should a few replies back is too young.
Good luck !
