Here we will teach you how to put in an old bike engine kit onto a bicycle. Before we start, it is essential to understand what you are getting into and everything you want to be certain setup goes as easy as possible.

Sprocket and Wheel Clamp Assembly:

Many sprocket clamp assemblies arrive with nine nuts and bolts, two rubber grommets, and one set of metal plates (although some engine kits might have 2). Most clamp assemblies arrive with 10mm bolts and studs, which means you will require a socket wrench to finish this area of the setup.

If you are using a coaster brake, first begin by taking away the coaster brake arms (be careful not inadvertently to disassemble the whole axle).

  • Cut a straight line between 2 of the holes on one of those grommets (not equally)
  • Afford the metal plates out of your meeting and align them on top of this grommet within the wheel and then align the sprocket using the grommets to Be Certain the spokes and grommet holes are aligned
  • Beginning from the inside of the wheel then ship every bolt through the grommet and sprocket and fold down them (Note: This helps to torque them at a star-shaped pattern)
  • As soon as you're done tightening the sprocket, and clamp assembly then set the wheel on the bicycle and bolt it down with high tension on the bike chain.

Note: We highly recommend using caliper or disk brakes even if you've got a coaster brake wheel. Due to the rates, you are going to be getting around. You will want to be certain to have additional stopping power compared to a coaster brake.

Mounting the Engine:

Mounting the Engine
  • Eliminate your front engine mount and engine mount bracket
  • Set the mounting plate to the motor over the empty engine mount stud vents
  • Mount both position bolts to the engine mount stud vents

To install vibration motor mounts:

  • Eliminate your engine mounts and engine mount brackets
  • Utilize the studs which came with all the newest mounts to fill in the engine mount stud vents
  • Twist the initial motor mount back to the studs, and then the shaking engine mount along with the
  • When those pieces are installed, it is possible to install the engine mount stud nuts.

Installing Your Clutch:

Installing Your Clutch
  • Take your inventory handlebar grips off the handlebars and slide onto the clutch lever
  • Twist the heat shield spring across the other end of the cable and then slip the cable through the clutch foundation screw
  • Twist the clutch spring across the cable, then slide the cable throughout the clutch arm on the motor (Note: loosen the clutch arm twist before sending the cable throughout the clutch arm)
  • Twist the clutch arm, so it is flush with the motor (i.e., it points back) tighten the pressure of this clutch cable so that it remains, then stretches the clutch down arm twist
  • Using your clutch arm pulled, you can pedal your bicycle as usual since the engine's disengaged. As soon as you release the clutch lever, then your motor will engage.

Chain Installation

Chain Installation

For easier installation of this string, begin by eliminating the clutch case cover (together with the clutch plate) and the drive sprocket situation cover. Doing so will assist the drive sprocket and clutch twist efficiently. Then get rid of the master connection in the string

  • Quantify the string on the back, and front sprockets subsequently get rid of any unnecessary connections (you will need a motorcycle string breaker to eliminate links). Note: you will want to depart.5" of slack on the string so that it does not snap
  • Reinstall the situation covers and elements
  • Put in the pulley in your back fork and put the underside portion of the string on top of the plastic idle wheel
  • Align the string so the upper and bottom parts of the series run across a straight route. If the chain Isn't right, it can slide off the sprockets and harm your spokes (and you, if you are not careful)

Throttle Installation:

Throttle Installation
  • Twist the beaded end of this cable to the cable jack from the throttle grip
  • Insert the clasp to the kill button casing, then slide the grip to the handlebars
  • Line the pin in the top of the kill button to the vent you've drilled, then twist the top and bottom portions of the kill button together, forming the throttle and kill switch assembly

Electrical Wiring

The spark plug, magneto, and the kill button have been already installed, so all you want to install from the CDI. It's possible to mount the CDI anyplace in your framework, so long as it is close enough to the spark plug to attach to it.

Now everything is prepared to cable, let us get it down:

  • Connect the black cable in the CDI to the black cable in the magneto and the green wire in the kill button. All these are your ground cables which can complete the circuit
  • Connect the blue wire in the CDI into the blue cord on the magneto and the yellow/red wire in the kill switch
  • Note: kill switch wiring coloring will change between motors and motor providers. These colors might not be your colours, but so long as you understand that floor cables you've got, it is merely a process of removal in which your cables are.
