Rolling Wrench  /  GY6 Swap Program

The GY6 Ruckus
Build Guide

Fourteen decisions, made simple. Work through each system in order, and we'll spec a complete, compatible GY6 swap, engine to exhaust, built to the standard we'd put on our own.

01Engine

GY6 150cc Engine

 

The foundation of every GY6 swap build.

View Product

Spark Plug

 

Because the engine comes with Chinese low grade spark plug, it's always a good idea to upgrade the quality so you don't run into any issues. This is a really nice Japanese NGK spark plug.

View Product

GY6 Brake Shoes

 

Because our engine does not come with brake shoes, you'll definitely want to add a set of these to your order.

View Product

Gear Oil

 

Because we ship the engine dry, you will need gear oil. This is pre-measured to the exact amount you will need.

Engine Oil

 

Because we ship the engine dry, you will need engine oil.

View Product

Short Axle Shaft Kit

 

If you're running a GY6, the stock-length axle sticks out too far. This shorty axle kit gives you a clean, flush fitment.

View Product

Gear Box Gasket

 

A gear box gasket for 150cc and 125cc GY6 4-stroke engines. Good to have on hand any time you're opening up the gearbox side cover.

View Product

02Engine Mount

Retains factory tire width and includes 8", 10", and 12.5" stretch options.

GY6 Wide Tire Center Shock Mount

 

This fully adjustable CNC billet aluminum engine mount with vibration dampening is our top-tier mount.

View Product

03Carburetor

CVK Carburetor

 

Simple reliable and eco-friendly carburetor setup. This is good for fuel economy, rather than performance.

View Product

PWK Carburetor

 

Performance focused carburetor upgrade. Best bang for your performance buck.

View Product

FCR Carburetor

 

As far as carburetors go, this is by far the best choice for performance. In short, this is a PWK style carburetor with an accelerator pump.

View Product

Electronic Fuel Injection Kit

 

This is the top-tier option. No carburetor tuning, 100% plug and play. All the performance with none of the jetting hassle.

View Product

04Clocking Flange

150cc Basic Flange

 

If you need a simple, budget-friendly way to level your carburetor, this clocking flange gets the job done.

View Product

Pro Flange

View Product

05Harness

✦ Recommended: Tailored Build

Tailored Wiring Harness

Our most popular option. Build your harness component by component, matched exactly to what your bike already has, with none of the compromises of a one-size-fits-all adapter kit.

20 Minute Harness

 

This is by far the quickest and easiest way to wire up the GY6 on your Ruckus. This is simply an adapter harness. You would choose this option if you plan on running a carburetor.

View Product

EFI Harness

 

This is by far the quickest and easiest way to wire up an EFI GY6 into your Ruckus. This is simply an adapter harness. You would choose this option if you plan on running Electronic Fuel Injection.

View Product

MetRuck Harness

 

This is by far the quickest and easiest way to wire up the GY6 on your MetRuck. This is simply an adapter harness. You would choose this option if you plan on running a carburetor on your MetRuck.

View Product

Lithium Scooter Battery

 

Although you may already have a battery, the GY6 requires a lot more amps to turn over. This is the battery we recommend.

View Product

06Throttle Cable

CVK Cable

 

This cable is designed for stretched Ruckus builds running a CVK carburetor.

View Product

PWK Throttle Cable - Fits FCR/EFI/PWK

 

This cable is designed for stretched Ruckus builds running our EFI system or FCR Carburetor.

View Product

07Brake Cable

Extended Brake Cable

 

Required for stretched GY6 builds running a drum style brake.

View Product

Cable Clocker

 

If you choose a wide tire drum brake option, definitely add this cable clock. This will keep the cable away from the rear wheel in a nice stylish way.

View Product

08Shock

Lowered Shock

 

If you're going for that low wide look on the rear end, you will want this lowered rear shock.

View Product

Stock Height Shock

 

If you're going for that OEM non-stretched skinny tire look, choose this shock. This will not work with a wide tire rear wheel.

View Product

Center Shock Mount Shock

 

If you're going all out with our billet CNC center shock mount, you will need to add this shock. This is custom made for our center shock mount.

View Product

09Rear Hub

FLP Drum Hub

 

This rear drum brake hub is a must with any GY6 swap when running a drum brake on the rear. This will allow an aftermarket wheel to be mounted to your GY6.

View Product

M10 x 1.25 Lug Nuts

 

The drum hub has two options for lugs, M10 or M12. Depending on the wheel you choose, you will need to choose the corresponding lug nut size. The most common size is M12.

View Product

M12 x 1.25 Lug Nuts

 

The drum hub has two options for lugs, M10 or M12. Depending on the wheel you choose, you will need to choose the corresponding lug nut size. The most common size is M12.

View Product

10Kickstand

Billet Kickstand

 

This is a very nice choice if you don't plan on lowering your Ruckus. If you chose a skinny tire setup, you will most likely want this kick stand. This will not work with a lowered Ruckus.

View Product

Lowered Kickstand

 

This is a traditional under-the-left-peg kickstand. One disadvantage to this option is the potential for scraping during hard cornering.

View Product

CVT Kickstand

 

This is a great option for lowered Ruckus builds. The only disadvantage is that it's difficult to flip out compared to the other options, but it won't scrape during hard cornering.

View Product

11Exhaust

ProBld Exhaust

 

Affordable hand tig-welded premium GY6 exhaust with carbon fiber muffler.

View Product

Yoshimura Carbon

 

This is the top-tier option for exhaust on a GY6. Full hand tig-welded header with premium Yoshimura carbon fiber muffler with a more 'bassy' sound.

View Product

Yoshimura Raw

 

This is the top-tier option for non carbon fiber fans. Full hand tig-welded header with premium Yoshimura raw muffler with a more 'tingy' sound.

View Product

O2 Sensor Reducer

 

If you chose to run an EFI system and one of our exhaust systems, you will need this reducer.

View Product

Baffle

 

If you chose one of our ProBld non Yoshimura exhaust systems and want to quiet down the noise level, add this baffle.

View Product

Exhaust Gasket w/ Studs and Nuts

 

This is a must for any GY6 swap. You're going to need exhaust nuts and a gasket.

View Product

12Wheel

3-Piece Custom Wheels

 

This is the top tier choice for wheels. If you want a perfectly true and stylish CNC wheel set, this is the ticket.

View Product

Skinny Wheel

 

If you chose a GY6 skinny wheel engine mount, this rim is perfect. It will replicate the stock look of the ruckus, and also allow the stock tire to be mounted to it.

View Product

Solid Wide Tire Wheel

 

If you're balling on a budget and you chose a wide tire engine mount, this is about as cheap as you're going to get for a rear wheel on your Ruckus.

View Product

13Tire

Wide Tire for 12" Fatty Rim

 

Choose this tire if you're running a 12x8 fatty rear wheel.

View Product

12"/13" Front & Rear Tire Bundle

 

Choose this tire set if you are purchasing a custom set of wheels.

View Product

Stock Tire

 

If you chose a skinny engine mount and are going for that stock look and don't want to use the stock tire off your old wheel, this is a direct replacement.

View Product

Tire Valve Stem

 

New wheels do not come with valve stems, it's a good idea to add them if you're buying new wheels.
