i believe that you are hearing driveshaft backlash that is just the nature of the beast. check your harness that plugs to your dashboard just probably loose or is corroded

 

Thanks for getting back to me. After some investigation I found a small cut in the harness that was giving it the intermittant signal. I can live with the backlash as long as I know it is not thrashing things inside. have a good Labor day!!!

 

I have 3 Kawies. 2 are quiet and one is not. It's just the luck of the draw. It is the straight cut gears in the tranny. Some are just louder than others. It is perfectly "normal" and you have nothing to worry about.

 

If this is the nature of the beast, then why does it only seem to do it when in low range? I rode today, and I don't get this noise in high range. It would seem like drive-train backlash would occur in any range.

has it done it since new?

 

that would be the engine brake control system. in low range they operate a little erratically. they are off on off on wich causes gear slap. both my quads have done it from day 1. both do not do it in high range at all, so i usually use high going down hills it is smoother and alot more quiet.

 

How does EBC system know whether the quad is in low or high range?

 

it does not know. but going down an incline in low can slow the machine down enough to cause the engine brake to release then grab again over and over wich will cause backlash. i have also noticed it is worse in 4 wheel drive than 2 wheel drive.

 

The engine brake fork engagement/realease threshold vehicle speed is 2 mph. In other words, less than 2 mph, it is always released to prevent engine stalling (OFF position). Above 2 mph, it is always engaged (ON position) - no such grabbing and releasing repeatedly on a good running KVF. If your engine brake is doing ON and OFF thing at above 2 mph, there is something wrong in the EBC or CVT part of your quad.

 

i am talking about going slow down a hill. i have had the engine brake release and freewheel a few feet before grabbing again on both of my 06 650i's. especially on rocky trails with alot of clattering. all in all i think his quad is fine.
