So I did my first clutch job on my '06 450 a couple months ago. IT seemed straight forward and it seemed to go together how it was suppose to. I soaked the plates in oil for 24 hours prior to putting them. The problem....I've raced a couple of desert races this year and on two of them where the course has had some deep sand and mud I've had to work the clutch quite a bit in sections where there has been other riders stuck. Eventually I can't completely disengage the clutch and I end up stalling it. It also keeps me from starting it in gear forcing me to shift to neutral to start it and jamming it in gear and hoping I don't have to stop or it will stall again. Once I get through the traffic jam and stop working the clutch the problem goes away and I can disengage the clutch if needed. I assume it is normal for clutch plates to swell when heated but is it typical for them to swell this much? If not, could it be something I did when I installed them? Like I said, it was my first time but it seemed straight forward.
