    Carb Kits -- all flat-slide
  1. 38mm Mikuni
  2. 39mm Keihin FCR
  3. 40mm Mikuni w/ accelerator pump
  4. 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 Modulation - 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.
