Stage 1 Shredder Head and Carburetor Bundle

This all-in-one head, carburetor, and accessories bundle saves you time, money, and takes the guess work out of building a powerful setup for any kart or minibike. This high performance induction bundle includes the following: 

• Assembled and ready to run PORTED Shredder Stage 1 cylinder head with 10% more flow than Stage 0 and upgraded valvetrain for higher RPMs.
• Head flows 90CFM and will take up to .400" max lift at the valve.
• Precision machined port matched billet cylinder head to carburetor adapter with stainless button head hex screws and o-ring seal. 
• Special thick ribbed fiber reinforced silicon rubber boot in your choice of five different colors with clamps.
• High quality 28mm PWK style carburetor with jet kit included.
• Large high flow cotton gauze air cleaner element with clamp. 

Everything you need from the head and induction side to get your Predator 212, 224, Ducar, or other small block GX200 style engine blistering fast! You can use stock length non-hemi pushrods with this head and intake combo and everything will bolt together perfectly. Add a billet connecting rod, flywheel, and Dyno 308 or 356 cam with stock length non-hemi chromoly pushrods for 20+HP. Remember that our Stage 0 Shredder head is equivalent to the other guy's Stage 3 heads. Our Stage 1 head flows an additional 10% over a Stage 0, and has 60lb dual springs setup at .947" for 34lbs of seat pressure, titanium retainers, medium groove keepers, lightweight lash caps, a laser cut steel guide plate, and heavy duty steel 1.2:1 rocker arms. 

If you are bolting one of these heads on any non-hemi Predator or other Rato engine you'll need our stepped head dowel pins to adapt the 11mm holes in the block to the 10mm holes in these heads.
