This is a Lifan brand 4 speed Semi-Auto electric start engine with lights!
Engine is assembled and ready to install. This engine bolts in the Honda style frame CT70, CRF50/ XR50. THIS WILL NOT FIT A HONDA ST90 WITHOUT FRAME MODIFICATION.  Stock footpegs will not work.  You will need our aftermarket footpeg assembly (TB148). There is a lighting coil in this engine.  This is a 12v CDI system so you will need to review your wiring needs for your application. 

Our engines are specifically made to OEM Honda standard diameter, so there is no special sprocket that is needed for your gearing options.       
Trailbuddy engines have an installed 420 front sprocket not a 428- so no need to worry about modifying or changing the rear sprocket you already have installed.  This will make it easier for you to gear your bike to either top or low end.  You can find the front and rear sprockets under the CT70 section in the subcategory “sprockets”. Our engines are not heavily gusseted by the top engine bolt which allow for a clean and easy mounting experience. You may want to install the motor with new mounting bolts, please see TB128 and TB129B, respectively.

Our engines also have a full wave rectifier which is a more efficient and smoother rectification.  A full wave rectifier is double the half wave because it converts both cycles of AC to DC.  The ripple factor is less in a full wave rectifier, so the waveform is smooth and easy to filter out.

It is highly recommended that you purchase this fuel switch to work with the carb that comes with our motors: https://mytrailbuddystore.com/fueltankswitch.aspx. The carb has a single fuel inlet while the gas tank will have a dual outlet. Also, please note that the electric start is on the bottom of the motor so you won't have to worry about reconfiguring where to place the carb/intake and air filter.  

The motor includes:
25mm Molkt Carb (92 Main Jet installed), intake manifold, gasket, bolts, spark plug, gear shift lever, kick start lever, 45mm black dual stage air filter, CDI, Ignition coil, 12v Full Wave Rectifier/Voltage Regulator.  

We have included additional insurance on all motors. The cost is already built into the handling fee.

***If you are wanting a higher performance carburetor, we highly recommend our Keihin carb.  https://mytrailbuddystore.com/pe24keihincarb.aspx
