Doing pre season maintinance on a new-to-me 06 800 Adrenalin 151 (has RKT head and probubly overbore kit). Sled has 3100 miles and change on the clock. I pulled the carbs for servicing and while I was that close I pulled the Reed Valves to check them and to look at the pistons, this is what I found...

Cold Compression is 139 PTO and 146 MAG so pretty good, sled runs fine. I think this was just a cold seize from the previous owner ??? and I should be ok to button it back up and ride. I was planning to do a top and bottum rebuild next summer anyway...but ... maybe now?
The real question here is about my crank bearings and a sound I hear when I rotate the primary clutch by hand. With the RAVE(s) and Reed valves off I can pretty much look into the lower crank and when I rotate the crank I hear a little "click-click", sounds just like 2 ball bearings falling way down in the crank case. The sound is a bit louder on the PTO side and happens when the PTO piston is near the top and bottum of it's stroke. Is this a normal sound??? or am I hosed and should be thinking of doing that rebuild now instead of next summer
The "click click" is not my primary clutch arms falling btw.
Any help would be appreciated.
