I allowed a mechanic to upgrade my 50 cc to a 80 cc . After completing the upgrade he relased it to me. I had it for 12 hours and it stop working. Not wanting to crank, his excuse to me was that i messed up the cylinder head. And i need to buy a new one. Why should i buy a new head when i only had the new 80cc upgrade for one day. Is it my fault? He said because i didnt break it in properly. However should it break in less than 24 hours. Attached is the pictures of my head. Should i buy another head 100 cc this time and allow him to fix it? Or should i take my buisness else where?
