Pocket Size Terror – Building a CRG ICC Shifter Kart


We used a heavy duty DID Gold Series O-ring 520 chain on new steel sprockets.  O-ring chains take up a little power and racing fanatics use a smaller non O-ring 420 chain and alloy sprockets to minimize weight and drag but we would rather have durability. 
We replaced the stock tubular steel pedal assembly with this billet highly adjustable pedal assembly from Wildkart.
We had to fabricate a new shift linkage as the TM K9 engine puts the shifter in a different place than a 125cc moto engine. 
The TM K9 engine has a sequentially shifted transmission just like a real race car. Pulling the lever towards you upshifts and pushing away downshifts.  You can play like you are driving a Daytona Prototype or something!  The clutch is used only for starts and is the hand lever opposite the shift lever.  To shift, you quickly lift the throttle for upshifts or blip for downshifts and tap the lever forwards or backwards.  The dog boxs literally sucks the transmission into the next gear. Shift like a wimp though and it will grind. 
The billet brake pedal is super adjustable like the gas pedal and is much stiffer than the stock tubular steel part.  This stiffness improves brake feel. The flex cable on the brake pedal is the safety cable that will allow you to have some braking if the rod fails.  The front tubular bumper is also part of the chassis tuning system. The hardware is designed to let the bumper be decoupled from the frame for additional front flex if desired or to couple the front bumper to make the front stiffer and have more grip. 
We use a MyChron4 electronic dash which is set up to read RPM, water temp and lap time.  It can also read GPS and EGT if desired. It has a warning light and a shift light.
