Trick 10.8 valve springs Restrictor plates clone High Flow filter cup with choke hold
  • The "Red Stripe" spring is the strongest 10.8 lb spring on the market and thus rightfully named Heavy Duty. The Heavy Duty clone spring will allow the engine builder to custom fit their spring kits. Having been through a specific process, which will reduce the amount of spring pressure loss from running in the engine, this spring will allow the engine to run a higher RPM before experiencing uncontroll ed valve float.

Electric Starter Clone / Honda Stroker kit


Our Stroker Kit for the Honda GX200, BSP, and Clone engines is the basis for building a +.175" stroker. This kit saves you more than $40 off the price of buying these items seperately!!! The kit includes:

  • ARC 6572-C 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, wrist pin, and cir-clips.

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 remove all the compression release components from your camshaft. 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)
