  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.
