At the 40,000 km service on my 2005 1200gs the Dealer did some computer updates that appear to have added fuel shut off on overrun . ( update is K25 ) This causes the bike to stumble on return to throttle and lean( noisy ) fire on shifting back gears . After the Dealer and BM Australia would do nothing I started fiddling with the throttle stop screws ( BBS ) and found that if I increased the idle speed with the LH BBS after I started the bike it would run fine again . Theory is that the computer does not sense a fully closed throttle and does not shut the fuel off in overrun situation . Problem is , have to re-do on every start and idle is bit high and iratic . Any suggestions appreciated , thinking of selling as riding is now annoying . John .
