i did a complete engine rebuild and Basically the clutch worked mint the first 2 pulls then it got really slack. I kept adjusting it but with in 10 minutes of riding it was all (cable and perch) adjusted to the max. I opened up the clutch all the all the plates are within spec and every thing is in proper order. The push rod that pushes open the clutch assembly appeared to be to short so I put a couple of washers in to try and fix the problem and same thing it worked normally for 10 min. if you space it out with washers the it work for a couple pulls then gets eveen worse. I have tried every thing some one please help me. thanks
