Expert Motorcycle Performance & Machine Shop Services
M/T Performance has been a leader in motorcycle performance and machine shop services for over 35 years. Founded in the late 1980s as JDM Fabrication in Chicago, we built our reputation working alongside industry pioneers like Ray Bellucci and Kent Stotz. Since relocating to Ashland City, Tennessee in 2007, weve continued delivering precision engineering under our current name, reflecting the partnership of Mark and Teresa Brown. Our expertise spans transmission undercutting, micro-polishing, cylinder head porting, and engine rebuilding for road, race, and ATV applications. We serve dealers worldwide with a direct approach that eliminates middlemen, ensuring the fastest turnaround times in the industry. Our racing heritage informs every service, from multi-angle valve jobs performed on Serdi equipment to carburetor and throttle body boring.By combining decades of experience with cutting-edge techniques, we enhance gear performance through friction-reducing micro-polishing that increases horsepower and component longevity. Our comprehensive offerings include connecting rod rebuilding, camshaft work, and custom cylinder block modifications. With a legacy rooted in competition and a commitment to innovation, we provide tailored solutions for vintage and modern motorcycles across all makes and models. Our clients trust us to optimize their machines for peak performance, backed by a deep understanding of both traditional craftsmanship and modern technological demands.

Services
Transmission Undercutting
We perform precision transmission undercutting for all motorcycle and ATV makes. This process strengthens gear teeth while reducing noise and wear. Our direct-service approach eliminates third-party delays, ensuring completed projects return faster than industry standards. Clients worldwide rely on this service for both vintage restorations and modern racing applications.
Micro-Polishing
Our micro-polishing service eliminates abrasive surfaces on gears and shafts. This specialized process creates ultra-smooth finishes that decrease friction and heat buildup. The result improves horsepower output while extending component lifespan. We integrate this service with transmission work to maximize mechanical efficiency for street and track vehicles.
Cylinder Head Porting
We offer comprehensive cylinder head modifications including porting, decking, and welding. Our technicians perform multi-angle valve jobs using Serdi equipment for precision sealing. This service enhances airflow dynamics, improving engine performance for both racing and street applications. We also replace valve seats and guides to restore factory specifications.
Connecting Rod Rebuilding
Our rod rebuilding service includes resizing, crack testing, and bearing surface restoration. We maintain strict tolerances to ensure proper alignment and durability. This critical service revitalizes performance components while maintaining structural integrity. We service rods for both vintage motorcycles and modern high-performance engines.
Carb Boring
We precision-bore carburetors and throttle bodies to optimize airflow. This service improves fuel delivery and throttle response for racing and modified street bikes. Our technicians maintain exacting standards to ensure smooth operation across RPM ranges. We service both single and multi-carburetor setups for various motorcycle platforms.
