Two stroke porting kit3/19/2023 I have been around motocross since 4-strokes were popular the first time (1968). Heads modified with Torque Grooves improve combustion efficiency thus reducing octane requirements, reducing the chance of detonation in which overall performance is increased. I also port and modify Rotary Valve engines as well. This will enhance every portion of the RPM's power delivery from off idle to top end. Intake and transfer flow will be improved by matching the transfer passages to the case. It is recommended that the Head be modified with Torque Grooves to reduce the chance of detonation, thus reducing octane requirements, giving you even more power. Over the years I have developed and field tested performance porting specs, which places priority on a wide powerband with a good back up torque. To accompany Race Porting, the Head should be modified with Torque Grooves to reduce the chance of detonation, thus reducing octane requirements, giving you even more power. Race porting gives you more power in the mid and at higher RPM's than basic trail porting. My Race Porting delivers maximum power for all out competition. So with that being understood, I can "taylor" your porting to suit your desired style, whether it be casual trail riding where you just want an increase in mid-range grunt or all out race where higher RPM power is desired or somewhere in-between. More Mid-Range to Top End is ideal for outdoor motocross, especially for intermediate to expert riders. More Low to Mid-Range is ideal for stadium style Supercross, off-road, or novices. I can (and will) truly taylor the porting working work to meet the specific type of powerband you are looking for. Changing the port shapes increases or decreases the flow, thereby changing the RPM and torque characteristics of the engine. Powerband Choices: Note that changing port timing and shape in a 2-stroke is in effect like changing cam shaft timing events, intake manifold design, carburetion and the exhaust system in a 4-stroke all in one complex operation. Combining this knowledge with the equipment needed for generating the best port shapes for maximum power without sacrificing reliability and ride-ability of your machine is one of my areas of expertise. I know the correct specs on how to modify intake, transfer and exhaust areas for increased power levels. Years porting successful race engines has provided me with a wealth of knowledge on the right type of cylinder modifications. Modifying the ports to higher power levels requires larger port areas for increased performance. No matter if it's a vintage motor or one of today's highly developed two stroke engines, you need experience to improve performance. All 2-stroke porting packages include complete porting, not the fake fluffy junk that most "In and Out" Porting or big time "SoCal" hop up shops offer. I perform all the porting myself and have worked with porting tools since the 1970s, porting countless cylinders and cases. Rich’s Taylored Porting offers all-inclusive porting packages for all types of 2 & 4-stroke engines used in Dirt & Street bikes, ATVs, Snowmobiles, Watercraft and Shifter Karts. Porting a modern 2-Stroke engine can improve the ride-ability of your machine as well as improve the power. Whether you’re into racing motocross or recreational dirtbikes, ATV or Snowsleds, for maximum performance, 2-Stroke Cylinder Porting from Rich’s Taylor'd Porting puts the “power” in powersports.
