Clicking sound?

Its kinda hard to make out the sound exactly from the video but it kinda sounds like piston slap to me, although I heard it through the worst speaker on the biggest pos phone on the planet. What's your compression at?
 
I'm not sure, i'll have to dig out my compression tester. The guy I bought it from claims that it was recently rebuilt (but we know how that goes). I'll try and find it to check and see. Compression seems god. It has a ton of pep. The sound quality of the video isnt that good, because I recorded it with my phone.
 
That definitely sounds off. Sounds like mine before I rebuilt it. The piston I had was loose enough it caused a crack in the skirt. I got lucky and only after I pulled it apart did the piece break off completely. Check compression and let us know the results.
 
If i'm pulling the cylinder, i'm just gonna rebuild it. It's only $125. Not a big deal. I've only got $530 invested. I'm still going to come out way ahead of buying one in running condition that I'd have to rebuild a year or 2 later anyway lol
 
my clicking sound...only thing was i only had between 97-110 lbs. maybe someone else can thrown in some ideas...:-/

it certainly does sound off. sounds like slapping if u listen really close on the video. i would pull the head off and check for clearance.
