.625 Goped Sport / XPED Long Drive Spindle

Does not fit G320 or marine/watercooled engines. 

This is a new Zenoah 28mm stroke crankshaft. This crankshaft was removed from a stock G290RC engine that was converted to a 30.5cc. These cranks may have light surface rust and will need to be cleaned before use. 

Fully ported GP460 engine complete with carb and clutch.

Complete fully modified/ported GP460 / GP470 long block for goped use. Long blocks are complete as shown in picture with reed crankcase, crankshaft and fully modified top end. Exhaust is not included and we recommend a Jetpro Rhino pipe to match.Transfer bowls have been modified so that a stuffing mod is not required like a stock case to increase power. Intake tract, reed valve and transfer bowls were in-house flow tested and dyno tested to produce as much power as possible. You can expect to see a lot more torque and mid range power then a piston port GP460 or GP470. We've used high quality carbon fiber reed petals for more power and longer life then fiberglass petals. 

Porting/machining:

intake port filled and 2 boost ports added

piston lightened/reshaped w/dual windows to match boost ports

all ports resurfaced

transfer port bridge knife edged

exhaust duration advanced

exhaust port widened and flowed

Replacement intake manifold gasket. Fits all CY and Zenoah engines from 22.5cc's-30.5cc's. Not compatible with G320/340 engines.
