I had my 02 zr 600 out this weekend for the first time and have come to notice the sled cuts in and out on the top end. The power seems to be normal up to about 60 but then cuts in and out from there. Some times it'll keep racing up till 95/100 but other times it won't go over 80. It's not a traction issue as it's obvious the motor isn't revving as freely as it should when it's cutting out. I'm thinking it could be the apv's sticking, has anyone had this type of problem and if so, what was the fix. Other then that I was amazed at how well the sled handled, it's unreal in the twisties.
