Potential Modifications
New Frame / Fuel Tank etc
- Mainly making it into a Powercube
- Could also in theory make it into a generator cart type thing, or a generator in a hush box
New Air Intake
- Uncertain how much it would help, but could use a Cold Air Intake type thing
Fuel Injection
- Would need an Open Source ECU , a new Wire Harness , a Fuel Pump/Rail, and the nozzles (probably plus either drilled+tapped holes, or a custom milled/cast cylinder head
- Port Injection, Direct Injection , or Dual Injection
New Piston
- Could have it DLC Coated (also potentially WPC treatment etc)
- Could REALLY benefit if you also used a 3D Printed Internal Combustion Engine Piston
