Default BF 750i engine brake

Just wondering if the engine brake is suppose to kinda grab and let go as you are descending a hill. My Kodiak was a constant brake feeling and I am not use to this one. Like I said, it feels as if it engages then disengages. Seems to be it should be engaged all the time. Thanks

It depends on the hill steep. It is normal for it to grab and let go lightly...if you just manage your throttle you can work around it.

Yes, it is normal for Kawis in certain condition.
The Kawi's engine brake system is different from Yami's, mainly because Yami uses a secondary clutch (centrifugal) on their tranny on their CVT quads. If you open up the CVT cover, the Yami's belt is always engaged between the drive converter sheaves and the Kawi's belt is loose between there (so that the engine doesn't stall). The Kawi's engine brake system prevents the engine from stalling when the quad slows down rapidly by releasing the engine brake forks from the ON position (pressing against the drive converter) to the OFF position (away from the converter)when the quad speed drops below 2 mph AND the deceleration of the quad is greater than a rate of 0.4G within an interval of 10 miliseconds. The above 2 conditions must be met. All this function is perfomred by Control unit which receives voltage signals from speedo sensor, fwd/rev sensor, EBC actuator potentiometer, etc. If any of the above things goes wrong, you will see 2/4WD flashing on your dashmeter.
