OHV or OHC

[4950cycle]

Doe's anybody know if the 4 stroke 50cc Honda/HauShangs (Red motors) are over head valve (OHV) or over head cam (OHC) ? I know the HF 79ccs are OHV. They ,OHV have a more limited rev range than an OHC motor. OHC motors hp comes in at a higher rev range usually. Doesn't seem to effect me though. I guess the Greyhonds OHV rev range is broad and high enough with the governer removed for my riding.

They are over head valve....not cam.

The smaller Hondas (GX35 and GX25) are overhead cammers, according to the Honda site:
Honda Engines - GX35 Mini 4-Stroke Engine

The 49cc Hondas are indeed pushrod, OHV engines.

Thank you for the info guys. I thought the Honda 49cc may have been overhead cam. I guess not. I wonder why they have a higher rev range than the 2.5 OHV Greyhound according to Gunter ? Must be the way their cammed ?

The little Honda revs so fast because it was designed to replace the standard 2-stroke weedeater type engine. Short stroke, and light parts capable of high revs
