Hello all. I installed a HM quickshifter and also a speedo. The speedo is up wire from it im pretty sure but not too far away. Will the HM interfere with the speedo reading being fairly close to it? I was so into downshifting using moto gp shift and the quickshifter I didnt realize till late in the ride my speed gauge was reading 8mph. I went one tooth down at front sprocket which is 15T and kept rear stock at 43T. I used the calculator and it gave me something like .864 to put in speedo. To me that doesnt seem right and possibly isnt. Or maybe its getting interference from the QS. Any advice would be greatly appreciated. Also i kno this is for another thread but does anyone ever hear a hissing sound at 60mph? It sounds to me like an overheated radiator releasing air.
