Pitbike head and piston change (YX 160)

We had some valve issues and we decided to update head to HC.
New engine snapped the valve and that lead to smashed piston and head so we decided to order new piston and cylinder with head (high compression).
Parts were ordered for YX 160 engine.
Part list:

    That bike is not running correctly, the rpms are floating. And are you sure there isnt any metal parts that flew to to the cases when the bike blew up? Might cause some damage in the future.

    Great video I didn’t think you could rebuild the pit bikes and sold mine when the compression went low now I see i made a mistake selling it saving for a mx bike tho

    hi, you can get it from ebay or aliexpress. Rubber boot mounts on intake with screws, but depending on intake you can use silicon hose in necessary diameter.
