Stage 1 Hop Up Kit for GX240, GX270, 9/11hp OHV, and 301
Basic kit for improving the performance of GX270s and 270/301cc OHVs. Simple to install, you can expect significant performance increases!

Kit Includes:
  • Race/Open Air Filter & Adapter
  • Heavy Duty Valve Springs
  • Offset Timing Key
  • #95 Main Jet
  • Optional Ignition Coil
  • Optional Twister Camshaft
  • Optional Header/Exhaust

*Note: UT2 series Hondas (2012 & up) have rev limited coils and will require a new coil to exceed 4000rpm. The UT2 coils (4 wire) can only be used with stock flywheels. If billet flywheel, you must run a UT1 style coil (single wire). Most “clones” & 301s have UT1 style coils already (however, some Lifans have a rev-limited digital ignition).
*Picture is for reference only and may show optional parts. See above description for actual content. Header not included unless specified.

Main Jet supplied works best with older Hondas and most clones. Newer Hondas (UT1) may require a bigger jet.
Filter should be sprayed with a K&N type oil, especially in dirt applications. Oil not included - click here.
Billet aluminum flywheel recommended. Stock flywheels, especially "clones", are prone to failure and are very dangerous!

WARNING: Header/pipe should be supported with a bracket/brace to either the frame or the engine; otherwise, pipe may fracture or break.
