Start with the motorcycle

Which bike are we building?

Choose the exact make, model, and year. We’ll save the bike, then continue into performance options built around the motorcycle and the goal.

Build power around the way you ride.

Street torque, touring power, or a complete motor build starts with the exact motorcycle, current combination, riding use, performance goal, and reliability priorities.

Start with the goal

A combination should work together.

A useful performance plan is more than a list of popular parts.

Tell us how the bike is used, where you want the power, what is already installed, what problems must be solved, and what matters most after the build. The answer may be a focused upgrade, a supporting change, more diagnosis, or a larger combination.

Build the combination. Prove the result.

Plan before parts

The current setup is part of the build.

Engine condition, intake, exhaust, calibration, clutch, gearing, fuel quality, heat, and rider use can all change what makes sense next.

Send the complete current combination. Unknowns stay visible until they are inspected, measured, or confirmed.

Performance paths

Choose the goal, then build the supporting system.

Every path begins with the motorcycle and current combination. Parts follow the plan.

Baseline

Condition and current setup

Document the bike, engine, mileage, existing parts, symptoms, and current behavior before choosing the next component.

Send the combination

Airflow

Intake, exhaust, and calibration

Treat airflow and calibration as a connected decision, with emissions and configuration boundaries kept visible.

Plan the system

Valvetrain

Cam and supporting parts

Match the cam path to the engine, riding use, current combination, required companions, and installation evidence.

Discuss the goal

Motor

Complete build planning

Define the target combination, supporting systems, unresolved measurements, and verification plan before the motor comes apart.

Street-first decisions

Useful power has to live on the motorcycle.

The right build depends on where the bike is ridden, the rpm range that matters, expected service life, fuel, heat, noise, and the rest of the drivetrain.

We keep those tradeoffs in the conversation instead of reducing the plan to a single peak number.

Performance. Reliability. Rideability.

Building it yourself

Use AVT for the parts, the plan, or the complete job.

DIY riders can start with the exact bike and upgrade goal, then shop the governed Engine and Performance catalog. When the project needs inspection, assembly, calibration, or a complete shop handoff, send the same context to AVT.
