Kits are grouped by the job on the bench, not by part number. Buy the bench you’re working — every kit includes the leads to land its sensors on the dongle. All kits are Coming Soon: listed now so you can plan the bench, sold only when they’re real.
THE HUB · EVERY BENCHCOMING SOON
The Pesky Dongle
The one piece everything else plugs into. Bluetooth hub that carries every sensor’s signal to your phone, keyed by its own serial number — that serial is your authenticity anchor and your support gate.
What it is
- Bluetooth dongle — pairs with your phone once, then reconnects on its own
- Sensor inputs for every kit on this page
- Unique serial number, registered to you at first log-in
- One dongle serves every bike in your garage
The bundle: buying the dongle includes one free month of everything — all diagnostics live, history saving, multi-bike, guided tuning. The clock starts at first serial registration, not at purchase. See below.

BENCH 01 · SYNCCOMING SOON
Carb Sync Kit
Balance two, three, or four carbs off one reading. A VStar is a two-carb bike, so this same kit covers it — there is no separate VStar sync kit.
In the box
- Vacuum / MAP pucks — start with a pair, expandable to 3 and 4
- Vacuum hoses and fittings for the intake taps
- In-line restrictors for a steady needle
- Leads to land each puck on the dongle
BENCH 02 · FUELCOMING SOON
AFR Wideband Kit
Know your mixture instead of guessing at it. The wideband O2 sensor reads the exhaust and the AFR diagnostic turns it into jetting decisions.
In the box
- Wideband O2 sensor
- Exhaust bung for a permanent mount
- Controller lead from sensor to dongle
- Heat-rated cable routing sleeve
BENCH 03 · TEMPCOMING SOON
Temperature Probe Kit
Four temperature stories at once — oil, head, intake air, and exhaust gas — so heat problems show up before they cost you an engine.
In the box
- Oil temperature probe
- Cylinder head temperature ring sensor
- Intake air temperature sensor
- EGT probe for the exhaust header
- Probe leads to land all four on the dongle
BENCH 04 · ELECTRICALCOMING SOON
Electrical & TPS Kit
Charging health and throttle position — the two electrical readings that explain a lot of “runs fine, then doesn’t” problems.
In the box
- Battery voltage lead with fused clips
- TPS breakout lead for live throttle sweeps
- Leads to land both on the dongle
VStar CV40 note: the TPS adapter for the single-carb conversion is not sold on its own — it ships only with the full manifold kit below, so it can’t be separated from the conversion it was built for.
BENCH 05 · ROLLINGCOMING SOON
Tire Pressure Kit
Pressures at a glance before you roll, and a warning when one starts walking away from the other.
In the box
- Valve-stem pressure sensors — front and rear pair
- Seals and spares for the valve caps
- Pairing card — the caps talk to the dongle, the dongle to your phone
BENCH 04 · ELECTRICALCOMING SOON
Compression Sensor
Cranking compression through the spark plug hole, read by the dongle instead of watched on a needle you have to be crouched next to.
In the box
- Compression pressure sensor with plug-hole adapters
- High-pressure hose
- Lead to land the sensor on the dongle

BENCH 02 · FUELIN VALIDATION
CV40 Single-Carb Conversion Kit — VStar 650
The Single Stack conversion: one Harley CV40 in place of the stock pair, on a printed manifold with the vacuum port built in. The TPS adapter ships with this kit only.
In the box
- Printed intake manifold with M6 vacuum port, insert pressed and hole drilled
- 0.062″ flange gaskets (RTV optional, per the instructions)
- 4 bonded washers
- Strip of Rescue Tape for the 40 mm adapter joint
- M6 vacuum barb + O-ring — or M6 bolt + bonded washer plug for AIS-deleted bikes
Why it’s not on sale: no kit ships until mid-range and top-end jetting is validated on the dyno, with the TPS connected. Validated jetting comes from a genuine Harley Keihin — results on a clone CV40 may differ.
BENCH 06 · COMPLETECOMING SOON
The Complete Bench
The whole store in one box: the dongle plus every kit above. For the rider who wants the full instrument panel live on every bike in the garage.
In the box
- The Pesky Dongle
- Carb Sync Kit · AFR Wideband Kit · Temperature Probe Kit
- Electrical & TPS Kit · Compression Sensor · Tire Pressure Kit
- One case that holds the dongle and every lead
Tony’s value anchor: dongle + six months of the platform lands around $120 all-in, against roughly $500 for equivalent standalone tools bought one at a time.
