  • JD Jetting Jet Kit

    Eric in NY

    Like having a whole new bike!

    All the forums said to use the JD jet kit in my 2006 Honda 250x and I was a little sceptical. But after installing it and riding they weren't wrong. This kit works great throttle response is excellent and it starts and runs so much better then it did before. My biggest issue was was hot starting and it completely solved that issue.

  • Tusk Fuel Mixture Screw

    Eric in NY

    It really makes adjusting the idle mixture possible!

    The fuel screw works really good. On my 06 250x it is still a bear to adjust even with this screw but now possible. The screw itself works great but on the bike there is very little room to get your hand in there. Overall I am very happy with it.

  • KTM Offroad/Bad Fuel Dongle

    James in CT

    only 2 modes for a 2019 690 Enduro R

    I have a 2019 690 Enduro R. Whilst it's handy to have this for offroad use, when I'm going between rides I have to use roads, sometimes in rain, and I'd like rear ABS engaged at that time. With this dongle attached, you can't. The alternate starting sequence for the engine (as included in the instructions) only applies to older models. So now I have to either take the seat off and unplug it, or I'm going to have to hack it and install a switch. Ridiculous.

  • Shindy Carburetor Repair Kit

    Michael in NC

    Inexpensive kit for mu sputtering bike

    I bought this bike which had been sitting for 8 months. The bike would barely Idle and would die when the throttle was twisted. I thoroughly cleaned the carb after removing all the components > i replaced all the jets, needles, springs, gaskets , and Orings. The bike started right up and is running great after changing out the bad fuel. Great value!
