Ok well I had some issues with my engine with the cylinder being damaged a piece of metal broke off of the transfer port and ruined the cylinder. I noticed when I put my finger in the connecting rod and pushed my bike there was a clicking noise and and a bit of metal on the fly wheel so I decided I had to do a complete tear down and clean it out.
I noticed that the cheap china bearings were not smooth I have already bought high quality replacement bearings. Now another issue is was the needle bearing on the bottom end crank broken and needs to be changed but I'm not sure how to get the crank wheel apart any suggestions? I know that I need to pop the pin but it's really in there methods?
