Your mirrors, like many are too short.
I really dislike the billet mirror extenders.
But I demand to ride with a good view of what's going on behind me!
I know at least one LIKE owner is using Vespa mirrors on his LIKE200i.
If the 1st & 2nd gen likes use a similar mirror - you might want to look into buying a pair of Vespa mirrors. They were about $20 ea. - but with the DT added fees on imports, think they are @$30 now. Come in gloss black, or chrome.
They are very good quality, and they don't look cobbed on.
Short one is stock KYMCO mirror taken off of my LIK200iLX. Longer one is stock Vespa/Piaggio.
If you're really in need of longer mirrors - you could get a set of my goofy looking Italian long-stemmed mirrors. I love them.
