i've got a KVF400, 2 wheel drive. runs w/o issue, however, when I give it gas, there is a delay. the motor responds immediately, but the unit doesn't start to move until the motor revs a good bit. once moving, there is very little delay. i pulled the cover off of the clutches, everything is working (all parts of the clutches, belt is in good working order, springs are working, no slop in the shaft or clutch mounts). i didn't note the clearances between the clutch bodies, but there was very little play and the bushings were in good order as well. I've never had an "automatic" atv, so not much experience, but it feels like an engine brake, even though the unit doesn't have one. I can compress the spring by hand about 1/2 an inch, but not any further. I jacked the unit up, put it in gear, the clutch is expanding. the belt doesn't grab immediately. i'm going to sand down the faces of the clutches, as they are really smooth and since i have to pull the clutches, i'll replace the belt. anything else i need to look at while i'm in there?
