Pmd31421 Posted April 14, 2017 Share Posted April 14, 2017 Hi my Yamaha Tdr250 is sitting at 2000 rpm for about 30 secs before it drops back down to normal tick over . Any idea why ? ( recently completely refurbed the carbs with new jets , floats etc.) Link to comment Share on other sites More sharing options...
Moderator Cynic Posted April 14, 2017 Moderator Share Posted April 14, 2017 Not good, do the revs drop quickly enough otherwise. Are the carbs properly balanced. Start easy and work up. Link to comment Share on other sites More sharing options...
