How parking spots and credits work
Assignment permanently activates the credit’s included motorcycle-profile benefits, whether or not you run a diagnostic. In the ordinary credit-based flow, the diagnostic allowance remains available until used. Eligible license holders can instead use a credit to open an extra spot beyond their allowance; diagnostics during the active license are covered by the license. A spot holds one profile and its records; archiving does not free it. Existing occupied profiles remain when a license lapses. Included benefits, license-only tools and new capacity depend on your entitlement.

Is this useful if my bike is running fine?
Yes. The toolkit includes pre-ride and general health checks, battery testing, motorcycle references and records. Your account also includes an Oil Change Tracker for the motorcycle in your starting spot. Paid access depends on the plan you choose.
Does anything connect to my motorcycle?
The diagnostic method follows symptoms you can observe through guided questions. Nothing plugs into the motorcycle, and the app does not read live sensor data or clear codes. Some checks and repairs require ordinary tools and appropriate experience.
How do I buy and use it on the web?
Open V-Twin Diagnostics on the web, iOS or Android, sign in and choose your plan. Use the same account across platforms to access your entitlement once the purchase clears. An account is required.
Home Mechanic or Professional Shop—which license is for me?
The Home Mechanic License is the starting recommendation for riders and home mechanics. The Professional Shop License includes everything in the Home Mechanic License and adds professional intake, comprehensive checks, estimates, catalog-wide torque lookup and Change Orders, plus ten included parking spots. The Smart Service Scheduler is a Professional Shop Tool.
Does it guarantee the cause of a problem?
No. Guided diagnostics help narrow a probable cause. They do not certify that a component has failed or that a motorcycle is safe to ride. Use the findings to inform the next check or a conversation with your mechanic.
Can I choose a one-time purchase?
Yes. Assigning a Diagnostic Credit activates its included motorcycle-profile benefits even before you need a diagnostic. In the ordinary credit-based flow, its diagnostic allowance remains available until used. Assignment is permanent; credits do not expire through passage of time. Home Mechanic Tools and Professional Shop Tools require their respective yearly licenses. Store refund rules and applicable consumer rights apply.
