HOW TO UPGRADE YOUR ENGINE
|
REMOVE THE GOVERNOR
The first modification should be to disable or remove the governor. The governor restricts the engine to 3600 RPM. With the governor disabled or removed, the RPM will increase to about 5200 resulting in a substantial increase in performance. There is a very easy way to disable the governor. see How to Remove the Governor
|
|
HIGH FLOW AIR FILTER
|
|
HIGH FLOW EXHAUST
The stock exhaust is also very restrictive. A favorite among Kart Racers, the RLV Header Pipe and Silencer will give you a substantial boost in power and that great sound for a low cost. You will need the Locking Collar to fasten the silencer. Also available for use on both Karts and Minibikes are the Fatty Exhaust and Stinger Exhausts Headers for Maximum Power and Awesome Sound

STAGE 1 KIT
|
CARB JETS: Upgrading the Intake and Exhaust usually requires re-jetting the Carburetor. If you have to play with your choke to get your engine to run properly, you need to adjust the Carb Main Jet. For the Stock Carb see
Honda Main Jets. The .035 Main Jet seems to work best but you may want to try .034, .035 and .036 to see which works best for your engine. For our Mikuni Carbs see
Mikuni Main Jets 120-140 for Curved Intake, 170-190 for the Inverted Intake. Open the Float Bowl, unscrew the jet and put in a larger size. see Mikuni Tuning Guide |
|
TOP PLATE
You will be removing the gas tank as part of your build. In addition to its billet aluminum good looks, the Top Plate supports installation of the Fuel Pump and optional Throttle Control. (if using a Mikuni Carb, you do not need to use the throttle control)
|
BOX STOCK KIT
Box Stock is the Beginner Class for Kart Racing. The Box Stock Kit has everything you need to upgrade your stock engine to the Box Stock Class except the exhaust. Kit includes the Top Plate, Chain Guard / Heat Shield, Angled Air Filter, Billet Air Filter Adapter, Fuel Pump, Fuel Line, Throttle Linkage and Hardware and more. Add the RLV Exhaust to complete this kit
|
|
UPGRADE THE VALVE SPRINGS
With the governor removed, the stock valve springs will be too weak to operate properly at high RPM. Installing stiffer 18lb Springs will prevent the valves from floating at high RPM
|
SPARK PLUG
Installing a 3910X Spark Plug costs about $7 and can add an amazing 3/4hp to your engine. This plug is longer than the stock plug and creates more compression. Also, this plug does not need to be gapped or indexed to operate at optimum performance
|
|
HEAD GASKET
We have seen thick stock head gaskets on an increasing number of engines. Replacing the stock gasket with a thin .010 gasket will decrease the size of the combustion chamber thereby increasing compression
|
|
FLYWHEEL
Before going any further with your engine upgrade, we recommend replacing your heavy 7 pound stock flywheel with a much lighter and better balanced
Billet Aluminum Flywheel. The stock flywheel is prone to failure at high rpm, which could result in serious injury. The lighter weight will boost your horsepower and acceleration
|
ROD
As the RPMs continue to increase, replacing the stock rod with a much stronger and lighter billet aluminum rod is needed to get from 5600rpm to 7200.
The ARC Rod is the best choice. It can be ordered stock length or It can also be ordered .010 or .020 longer to increase compression without machining the block, a big boost
|
CAM
For the Box Stock Class, use the CL1-Improved Cam to follow the racing rules. If you don't care about rules, you can use the Superbox CM .275 Cam, which is as hot as you can go without Rocker-Arm upgrade
|
SUPERBOX UPGRADE KIT
The Superbox Class is the advanced Clone Kart Racing Class. If you have a Box Stock Engine (Box Stock Kit installed) this Superbox Upgrade Kit will provide you with all the parts needed to upgrade to the more powerful Superbox class
|
