I went riding last night and on the way home the sled started acting up. It would kind of load up and not rev out all the way. I ran it this morning and the same thing happened. It would fight its way to 7200 rpm and thats all it had. I thought it might be power valve related so I checked and cleaned those. Tested the servo motor off the sled. Then I put the servo motor back on and ran it on the stand and it operated fine. Right after I ran it on the stand the track didn't spin real freely but once I got it back into the shop it was fine. So this leads me to believe something is going on in the clutching? I'm running the same setup I ran last weekend with 76 gram weights 44/40 helix orange primary spring, orange/white secondary at sea level. Wash and plugs looked fine when I checked them. Does anyone have any other suggestions of things I should check or what my problem might be? When it was on the stand I saw 7700 rpm's once but it still didn't seem right.
