A few months back I purchased a used 2017 F700GS for my wife. She was having problems stalling in first gear, which IMHO, was way too tall! So, did my research an installed a 16T front sprocket.. Much better we thought..! Well, not long after, she started having problems with the gear indicator going out. It only happened once she hit 6th gear and would randomly come back on after gearing down. Sometimes it would take awhile (even after stopping and starting), sometimes it would come back right away. Figured it was the potentiometer, which the dealer replaced (bike still under warranty). But that did not fix it.. Happened again not long after we picked the bike up (as soon as she hit 6th!). So, took it back and now they are telling me it was the sprocket change that is causing the problem! Apparently, the computer gets 'confused' once the bike is in 6th, and can't really tell what gear it is in. From reading the forums, a lot of people have made this swap and yet I've never seen where anyone has experienced the same problem! The bike is still at the shop, waiting for a new 17T (stock) sprocket.. I suppose I could put the old one in just to check and see if that fixes this, but it is a bit worn so it would have to be replaced soon anyway.. But my question: Does this make sense? Has anyone else swapped a 17T for 16T (or any other swap on a BMW twin for that matter) experienced this same issue? Or is this something unique to the 2017+ models? And yes, I've searched through the forums and haven't found this mentioned.. Changing sprocket sizes is such a common thing on motorcycles, and yet I've never heard of any others having such issues.
