Does a QT50 cylinder head and piston fit on a YT60 engine?

[200XMichigan]

I saw that people were putting YT60 engine top ends on QT50 mopeds. Mopeds are really common in Europe so I figured someone would sell a whole kit. Wouldn't this kit work on any YT or YF60 and just take it down 10cc.

There are kits for QT50s, and QT50 riders do use the YT60 top ends so this should work.

I have a fleet of QTs with YT60 top ends, they run great, if anyone has any oil injectors or YT cylinder heads laying around I am interested. The YT heads help the cooling and our QTs get way hot with the PW80 carb on there.

Yep, I had posted that link a while back to see if anyone had tried that kit on a Tri-zinger.. That would be nice with a Jemco pipe on a Tri-zinger

It really should work, pretty much all of the parts interchange between YTs and QTs in the engine department, The only difference I know of is the lighting coil on the moped stator and I believe the YT60 has a little wider clutch (haven't verified that though).

I know the YT top end and intake will work with QT50s and surprisingly enough a 2004 PW80 carb slides on to the intake with no modifications. Not sure how the throttle and choke cables would work with the tri zinger though.
