I have a brand new cforce 800 xc.  What a machine!  All the bells and whistles I could dream of having!

I'm about 6 hours into break-in.  I'm noticing a hesitation in the engine at 4,000 rpm.  It only happens when crossing through the rpm range.  Everything is buttery smooth below that engine speed and above that engine speed.  But it's like the computer is temporarily cutting fuel or something similar. 

Has anyone experienced this before? 

I did notice a pause in the rpm not sure exactly whereabouts as I never looked, I do know that alot of the problems I had with it went after disconnecting the cannister!

Hola chicos, yo tengo el mismo problema, alguien lo ha solucionado? un saludo
