Yamaha FX 140/ MR-1 Engines, TPS adjustment made easy, No need to pull the fuel injection Assembly to adjust and install, Watch HOW to DIY, @ Yamaha TPS HACK, YouTube.com/watch?v=0FtXKjvPaaw, I will replace the duct Tape with Nylon plugs later and use silicone to seal them. No more hassle to adjust TPS or Replace it!!!
