  • Race/Open Air Filter & Adapter,
  • HD Valve Springs
  • Offset Timing Key,
  • Main Jet correct for application
  • Pilot Jet
  • Choke Hold Down Bracket
  • Optional Header/Exhaust

Picture for reference only and may show optional parts. See above description for actual content. Header not included unless specified.

Filter should be sprayed with K&N type oil, especially in dirt applications. Oil not included click here

Billet Aluminum flywheel recommended. Stock flywheels, esp "Clone" are prone to failure and very DANGEROUS

Note: UT2s series Hondas (2012 & up) or have Rev Limited coils and will require a new coil to exceed 4000 rpm. The UT2 coils (4 wire) can only be used with stock flywheels. If billet Flywheels, 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)

1 of 5 Hop up kit for 9hp August 27, 2018
Reviewer: robert mcmullen from Maryland  
This ad is misleading because payed $71.33 for a filter an 2 springs I could have went to go power sport an payed $35.00 for the filter I didn't need any springs. The reason I brought the kit because I thought the muffler came with it. You need to redo this web page very misleading.😩
