  • Throttle positioning sensor?

    I'm going to have Duke do my TPS on my HSR42 - I was just going to order a new one but they are $150 on RRP. I'm not opposed to just buying one, especially since my stock carb is 19 years old. But, the question is, do they actually wear out and it would be fine to use the one on the stock carb or is buying new the best choice? What say you?

      I just bought a stock Roadstar carb with 25k miles on it complete for $50.....I sure as shit would not spend $150 on one tiny little piece that wasn't broken.

        Jaybo, the Suzuki SV650,SV1000, and the V Storm TPS will work but you have to extend the wires. I'll get one off EBay that's going for $26.99 right now. I'll check it out and extend the wires.

        Just ordered,

        The TPS have a very good reliability record, and I haven't heard of any going bad.

          You can test the TPS with a multimeter. The procedure is in the manual.

              When setting up your carb, you should make it a standard procedure to check the TPS.

                i finally got a chance to put some miles on my bike yesterday after the TPS mod. I had previously put the Harley VOES sensor on and when I did it it seemed to work fine. If you did the VOES or left it off when you did the HSR 42 carb, you are missing out. There is an obvious difference in performance. much improved throttle response, everywhere. Didn't do much for my mileage since I was hitting on it pretty hard on my 150-ish mile ride yesterday. It was making me giggle too much! Especially after hte last ride being that dog turn HD Road Glide in Mexico... Well worth every single penny I spent having Duke set me up! Thank you sir!

                  Your more than welcome Jaybo. I enjoy doing this stuff on our Road Stars.
                  I'm really glad it's working out for you and your happy.
                  The best fuel mileage I've had with the HSR 42 is around 40mpg cruising.
