  • Lectron High Velocity Adjustable Power Jet Carburetor Kit

    John in TX

    Best upgrade ever!!!

    This carburetor is simply awesome. Purchased for my 2006 Honda Cr250r. I constantly had jetting issues with the factory carb. Could never get it quite right, and really had me lacking the interest to ride anymore. After about 6 months on the fence about purchasing this carb, finally pulled the trigger. Was kinda tight to install but so is the factory one. Other than that, no issues. Filled the bike up up with fresh premix, two kicks and it started. Idle was a little high for my liking, turned it down which is easy to do and wow is it crisp! Don't know how they do it but is amazing. Took it to the track the next day and wow. I had to basically relearn how to ride the bike. It has so much bottom end now and simply screams. Can't wait to go out next weekend. If you're on the fence like I was about buying it, just do it. The smiles it gives you far out weighs the cost. If I ever buy a newer 2 stroke, this would be the first upgrade I would buy!

  • Tusk Cold Start Jet Kit

    Shon in NV

    Solid Upgrade!

    I picked up two of these. One for a TTR50 and one for a KLX140L. They work perfectly. Before these I would have to run the choke on both bikes for a long time... now it’s literally less than a min even after not starting them for a few days. Such a solid upgrade for super cheap. I’ll be buying more for the rest of the bikes as well.

  • JD Jetting Power Surge 6X Fuel Injection Tuner

    David in OH

    Helped gnarly and RK Tek

    This product worked well for me to compensate for performance modifications on a 2019 300 TPI. Adding the gnarly pipe, RK head, and turbine core exhaust left the bike lean, this controller allowed the addition and removal of fuel injected to the mixture at critical points throughout the powerband.

  • Tusk Air Adjustment Screw

    Craig in WA

    No tools needed

    Nice to adjust without needing tools, a little larger knob would help when wearing gloves!
