I fiddled with the index/friction lever on a 7 speed Ultegra barend/downtube shifter while it wasn't mounted to anything and now the indexing is kaput (goes, click, click, long swing, click or something like that instead of click, click, click, click, click, click).
After fiddling I read something online (possibly a Shimano tech doc) that intimated the index/friction lever should not be operated with the shifter unmounted.
Have a buggerfucked it or is there a way to save it? I can't really see any way to get in to the indexing mechanism.
This is the shifter if it helps.
