Racc Posted August 5, 2011 Share Posted August 5, 2011 Hi, can't get my yzf750 to rev over 10k even when slipping the clutch it goes upto the amount it slipped to and stops, feels like it has a flat spot about 7k in high gears, air filter is clean plugs are new, if is cold about 5c, it won't rev over 7k Any help appreciated Link to comment Share on other sites More sharing options...
bonzoid60 Posted August 8, 2011 Share Posted August 8, 2011 Have you checked the EXUP valve? Link to comment Share on other sites More sharing options...
Racc Posted August 9, 2011 Author Share Posted August 9, 2011 I will, but I though that it caused problems about 4000 rpm if it wasn't working ? Not high end revs Link to comment Share on other sites More sharing options...
Racc Posted August 10, 2011 Author Share Posted August 10, 2011 Right, the exup valve doesn't move when the ignition is switched on but moves when the engine is reved, it's a 1994 bike if it makes a difference Link to comment Share on other sites More sharing options...
