caseysherco Posted August 5, 2010 Report Share Posted August 5, 2010 Hi, Just bought a sherco 290. when you rev it up abit it seems to take a while for the revs to go down. Any ideas why this is ? Thanks Quote Link to comment Share on other sites More sharing options...
caseysherco Posted August 5, 2010 Author Report Share Posted August 5, 2010 after watching some videos on youtube it seems this might be normal ? Quote Link to comment Share on other sites More sharing options...
copemech Posted August 6, 2010 Report Share Posted August 6, 2010 Of course if you rev them high, takes a bit to come back down due to the flyweight effect. If you barely rev them and the revs linger and float and such, likely a dirty carby or mix screw set too lean. Or other issues! Quote Link to comment Share on other sites More sharing options...
