6573-KIT Stroker Kit

Product Description

Our Stroker Kit for the Honda GX200, BSP, and Clone engines is the basis for building a +.175" stroker. The kit includes:

• ARC 6573 Billet Chromoly Stroker Crank
• ARC 6265 Billet Aluminum Stroker Connecting Rod with bearing inserts
• ARC 6618 SFI Certified Billet Aluminum Flywheel with Indexed Adjustable Ignition Timing
• Wiseco 11132PS Piston with rings and cir-clips.
• Arc 6521 Wrist pin

You must cut down the top of the piston by test-installing the parts and measuring to see how much needs to be taken off.  We recommend either the Viton coated head gaskets or copper head gaskets.  The only thing you will have to do with these parts besides proper assembly is hone the cylinder to fit the piston, set ring gap, and set rod oil clearance. The bottom of the cylinder and the camshaft may also need to be ground slightly for clearance depending on your cam and engine block choice.
Besides the regular external bolt-on parts, we suggest the following other High Performance parts for a stroker engine build (not included with kit):

• DJ-1121 25mm Stainless Intake Valve -OR-  DJ-1122 28.5mm Stainless Intake Valve
