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

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.
