Inside the mighty YZ

Hi all, I have just finished rebuilding a yz80, I put a 49mm wiseco piston kit in it and replaced the crank bearings and seals. After assembling it I kicked it a few times and it fired up nice(for about 15 seconds) but then stopped. After that it was very hard to turn over. I drained the oil and removed the clutch cover and all freed up. Put it together and turned it over a few times and after a few kicks it started to tighten up on me again until it wont turn any more!!! I took the plug out and exhaust off to have a spy on the cylinder, all looks good in there. The kick start lever is still engaging but wont turn it over. It almost feels like its hydraulicing somewhere......  Can anyone shed a little light on this?  

 

Cheers

 

Rob

Did you mix oil with the gas?
