• Carb Kits -- all flat-slide
    • 38mm Mikuni
    • 39mm Keihin FCR
    • 40mm Mikuni w/ accelerator pump
    • 42mm Mikuni pumper

    • Microsquirt ignition control, BUT - Complete carb kits with throttles and cables that reach and perform.
    • Push and Pull cables that are hooked up. Sorry, but ALL Bigtwins LLC goods are all black with very few exceptions.
    • The Problem is that the MicroSquirt does not have Pulse Width Moulation - which inexpensive devices such as the Arduino 2560 R3 do possess.
    • Look for a combination of Raspberry/Banana/Organge PI and Arduino combos to handle fueling. The MegaSquirt is a minimum of $1100.
    • In the meantime look for 42mm and 45mm HSR Mikuni Systems. Yes, I understank that FCR systenms can squeese out smoother a power-band and higherr peaks, but it is a nit-picking job that is almost as much work as EFI.

  • Microsquirt(maybe)-based EFI and ignition control
  • Ecotrons-based EFI and ignition control

  • Ignitech ignitions and other controls

  • Big Bore Kits

  • Stroked and Balanced Cranks
    • 75mm V Star - Several in stock
    • 84mm Probably - Not cheap
    • 87mm Unlikely

  • Needle Bearing Heads -- Cams and Rockers

  • Exhausts

  • XV-Friendly Tools
    • Valve Spring Compressors
    • Pullers
      • Crank
      • Rocker Shaft
      • Alternator Rotor
      • Main Bearings

  • Machining Services

  • Double Row Bearing Kits

  • Stainless Hardware Kits

  • Titanium Studs

  • Compression Releases

  • Kick Start Kits? Unlikely

  • Four Valve Head Kits -- Expensive!

  • Shaft-to-Chain/Belt Conversions -- Eventually.
