so like, i want to rebuild this za50 i got. it works, last i checked, but it has like 12k miles on it and was getting "chattery." i have another bottom end to use for parts. plan is to get it all set up with new bearings and a new crank and match it to some little kit. probably an airsal. i'm at the point where i feel like i almost just want to pay somebody a bunch of money to do it...like a few hundo. it would have to be somebody really well known and respected within the community...like, i wouldn't do it unless i was really sure they were gonna do a better job than me. i "can" do it. im just lazy, and za's r hard....
