Description
TSP’s unique TPI Injector Relocation Kit (IRK) combines the best of TPI with the best of TBI in one package.
The TSP IRK kit moves one injector to the intake (TBI) and leaves one injector in the stock TPI location. Combined with the TSP custom ECU mapping which is designed specifically for the TSP IRK, the power delivery is next level and allows us to deliver the best of both worlds… the smoothness on/off the throttle of the TPI combined with the mid range and top end power increase of the TBI setup. The TSP IRK kit allows you to run premix, or you can continue to run the stock oil pump. The kit comes with all the necessary hardware for a simple installation… including fuel hose, hose clamps, an injector blank (installed in the right side of the cylinder) and a 3D aluminum printed injector mount. You will need to disassemble the stock fuel line and utilize some of the existing components, however there is no modification required, so it can always be put back to stock if necessary.
It is strongly recommend to install this kit with a TSP ECU re-flash and TSP head to take full advantage of the relocation benefits. With your ECU, we have control over the injector timing & phasing, which will drastically improve the smoothness & reliability of your TPI bike. The fuel pooling in the video example cannot be changed unless we change the ECU mapping. We also have access to fuel, ignition and oil maps to make the bike much more responsive, smooth and predictable, while offering more power and reliability over stock.
For customers who have previously purchased a TPI power kit that want to purchase this injector relocation kit, we will be offering the ECU re-flash update at a significant discount to these returning customers.
If you choose to run premix, not required, you will need a TSP Oil Pump Delete Kit plug and play loom available for purchase as a separate kit on our web site.
