  Boyesen Rad Valve

  John in CA

  The best upgrade

  I put this on my yz250 and when on the track I was blown away with the power and response. More low end and more over rev and crisp throttle response. I dropped the main jet one size to a 175 and pilot jet one size to a 48. It also has a pro circuit pipe...The bike feels like a whole new bike, jumps I had to click into 4th can be done easily in 3rd now with throttle to spair. If I could give it 10 stars I would.

  Helix Racing Products Fuel Line

  Wyatt in AZ

  Good

  Good quality fuel hose. I have not had fuel in the line for long periods of time and cannot comment on how well they hold up to fuel with ethanol added. It functions well and is at a price point where if it discolors can be replaced at a reasonable cost.

  Tusk Carburetor Vent Line

  Matthew in MD

  Good Option

  Worked well to replace vent lines on carburetor rebuild for 2006 KX450F. The red color is truly red - not the clearish pink you might see on some bikes.

  Tusk Fuel Mixture Screw

  Michael in CA

  tusk fuel screw

  Heard a lot about these screws having a habit of falling out of my YZ400F OEM carb, but decided to give it a shot anyways. I love this thing so much better than the OEM mixture screw. It will sit really close to the carb drain plug though. Been about 8 months and still has yet to fall out or lose adjustment.
