  Cometic Top End Gasket Set

  Titus in AZ

  Way better than I thought

  Doing a rebuild on my entire motor needed just a head gasket so got this thinking I should replace all my seals for the price I wasn't expecting everything to be this amazing all the rubber seated perfectly definitely worth the money.

  Wiseco Piston Kit

  Jack in ID

  Great pistons

  I love wiseco pistons. They always fit well, they look great (which feel reassuring when doing the top end rebuild). I will always buy wiseco pistons.

  Steahly Heavy Flywheel Weight

  Wyatt in AZ

  11oz really mellowed out the YZ250X

  Changed the riding characteristics of the bike completely. Really mellowed out my YZ250X build. Still hits hard up top but much more single track friendly down low.
