Questions: Do you mean a daVinci Grand Junction? Did you buy it new?
Suggestion: If you haven't done so and assuming you bought the tandem new, let your dealer and/or daVinci know about your shifting concerns and see what they have to offer. The original owner of a daVinci (or just about any other reputable brand of tandem
), post-sale support is part of what you pay for. Moreover, they may have already encountered the same issue with other owners and may have a ready solution.
My assessment: It sounds like a basic cable or cable housing problem, i.e., there's a kink in the cable, the cable housing isn't seated correctly, a cable-end wasn't fitted with a ferrule, or there's simply too much cable housing. If it were me, I'd probably pull the cable and housing off the bike, inspect it and then do a reinstallation by the book, making sure there was no excess cable housing, that the ends were all cut cleanly, and ferrules were installed followed by a good pre-stretch of the cable once it was re-installed. After that, fine tune the movement using the barrel adjusters at the cable stop (assuming they still fit those to Shimano's Tiagra level components
