Stage 4 Hop Up Kit for 208cc DuroMax
For serious engine builders looking for great power and good reliability, we offer our Stage 4 kit. This package is similar to that of the Stage 3 kit, but adds a ported and milled head, stainless valves, billet rockers, a flat-top piston, and a great all-around cam package.

Kit Includes:
  • Ported & Milled 22cc "Clone" Head
  • Approximately 11:1 Compression Ratio for Use with Pump Gas
  • Stainless High-flow 27mm Intake & 24mm Exhaust
  • 37lb Springs
  • 1.2 Ratio Billet Rocker Arms
  • Chrome Moly Pushrods
  • 280-0611 Camshaft
  • Stud Kit
  • Lash Caps
  • Billet Rod
  • 70mm Flat-Top piston
  • Piston Rings, Wrist Pin, and Clips
  • Billet Guide Plate
  • Full Gasket Kit (Not pictured)
  • Choice of Carbs (Or use customer supplied carb)
  • Optional Flywheels

*Note: These kits are intended for experienced engine builders. Some clearancing, fitment, or other engine building "tricks" may be needed. This kit will not fit Harbor Freight 212cc (Predator) engines. Please see our 212 Predator kits for those applications. Picture is for reference only. Actual content is based on above description and customer selections. (In other words, the flywheel shown is optional.) Filter should be sprayed K&N type oil, especially in dirt applications. Oil not included - click here. Aluminum flywheel REQUIRED. Stock flywheels are prone to failure and are very DANGEROUS.

Due to the head work involved in this kit, please allow 1 week before shipping.
