just did cr10ek plugs, airbox mod, 7.5 bar riser....first ride out no hot start issues starts way better, the power is better and the airbox sounds much better. However something has come up.

During my 150 mile ride today i noticed something odd....between 0-15% throttle some times the sled would kinda glitch....it is almost like someone is flicking a switch as fast as possible on the engines electrical. It cuts out super super quick and you get a abrupt clutch backshift.

To describe it, its like -0 throttle its like the engine dead stopped for a micro second causing the clutch to back shift hard.

This happens randomly and only at that 0-15% throttle....anything more nothing never skip a beat.....when it does this its not a studder, sputter or cough it feels electrical....the motor is still responsive and if you snap the throttle its there.

My first thought is throttle cable and tps issue. What do you guys think?
 
It sounds like what was happening to myn and the throttle was to tight. Loosen it up a couple turns and see what happens. You can also go into diagnostic mod by holding the two lower buttons down until the screen changes. Scroll through until you see diag then you can see what percentage your tps is. Myn was 3% at no throttle so too tight.
