Picked up a 1980 Yamaha yz80 for cheap, PO mentioned bike was dumped then would not start/run and was put away for approx. 2yrs. I cleaned out the mice nest from the airbox, carb was somewhat rebuilt and tank was cleaned. It was dropped on the left side, so the shift lever is slightly bent and the clutch cable perch (I think) was a little bent. I put a new plug in it and tried to bump start it with no success. What's odd is when trying to kick start in neutral, the bike will go into gear. Any ideas on where to start to get it started/running? Thanks.
