Part Number: PRRCMAXS71
Availability: In Stock.

The RCMAX 71 is a legendary engine in our range, proven over many years and recently taken to the next level with our Game Changing Supreme Cylinder! 


This Complete 71cc Dragster engine package comes with everything you need to fit the billet
reed engine into your car and get down the track! This engine is for experienced users only and comes with our Monster 110mm clutch system, custom gear plate and gears plus all new fitting brackets to replace the stock ones on both sides of the car!

Fitment mods needed to the car:

  • You will have to throw away your plastic dragster cockpit cage due to the sheer size of the engine!
  • A small piece of dremel work is needed to the brake mount and top tranny plate as shown in the photos before and after pics. This is to accept the monster 110mm clutch


The WJ71 carb will come preset on rich settings ready for bedding-in the engine while you get
used to the massive increase in Horsepower and torque. You will be supplied a free Yamadude linkage set so you can make up your linkage similar (or better!) than we have done as an example in the photos.
