New 44mm head for Honda Hobbit, PA50, Camino, etc.
Oversized head increases cooling potential. It also features angled spark plug hole and eliminates the decompression valve. This may make your bike tougher to start unless you install a kickstart or pullstart assembly. It also eliminates the possibility of a leaky decomp.
This cylinder head is thicker than your stock Honda head. Longer studs or bolts may be necessary for installation. The cylinder stud holes are now 37.5mm thick.
New design measures 154mm wide and 145mm tall.
