GP35 4-Stroke Engine (Go-Ped Variant of the Lifan 139F)

GP35 Engine (Go-Ped Variant of the Lifan 139F) 4-Stroke 35cc, 1.5hp.

The torquey GP35 engine begins the Gen 4 era and answers the call of many Go-Ped enthusiasts for a 4 stroke version.  It also accomplishes adapting to new regulations phasing out the importation and use of 2-cycle engines.  The engine is much cleaner running, quieter, and far better fuel efficiency (running on straight unleaded gasoline)

Interchangeable on Go-Ped models using a 78mm motor mount.  

Note:  The motor mount requires the 4 stroke version motor mount billet housing (PN: 2121300714) Internal motor mount parts (bearing, clutch drum, snap rings) are interchangeable between the two stroke motor mount and 4-stroke motor mount.  

A small modification is required to the frame's motor mount bracket on 2-cycle model frames to allow the engine to pivot sufficiently to properly adjust the chain (photo to come).

 IMPORTANT!  The engine mount bolts for this engine are shorter than the 2-stroke engine bolts  M6-30 rather than M6-35.  Using the longer bolts will damage the engine!!!
