Performance Machine Works

Welcome To Our "Performance Machine Works" Page by Matto Cycle In Where We Specialize In Cylinder Head Work For Applications Such As MX/Offroad, ATV and Race Bike Engines and General Purpose Riders Our Work Is Designed To Increase Performance and Efficiency For Your Honda, KTM, Yamaha, Suzuki, Kawasaki, Polaris, Can-Am, Beta, Gas Gas, Triumph, Harley, Indian and BMW Cylinder Heads. Most of The Performance Comes From "Multi Angle Valve Seat Machining" This Improves The Profile of The Valve Seat and Increases Air Flow Velocity and Extends Valve Life.

For Racing Cylinder Heads We Use Copper Beryllium Seats and Titanium Valve Set-Ups, These Are Softer and Lighter Parts, So They Wear Faster, But Provide A Very Powerful Performance and Increase Acceleration. This Set-Up Is More Designed For Pure Racing, If Your A General Purpose Rider We Do Recommend The Standard Set-Up of Stainless Steel Valves.


Once We Receive Your Engine We Completely Disassemble, Clean, Inspect and Replace/Repair Parts That Are Needed Such As Cylinder Head, Cylinder, Crankshaft, Bearings, Clutch, Gears, Camshaft, Timing Chain, Oil Pump, Water Pump etc. We Re-Assemble Your Engine With Fresh New Gaskets/Seals and The New/Reconditioned Parts, We Rebuild and True The Crank, Ball Hone The Cylinder, Install New Piston & Rings and Install The Reconditioned Cylinder Head (See Above)
