Who is KMT?

We are Motorists – Scooter and Motorcycle enthusiasts. We love machining complex parts and have been in the manufacturing industry for almost two decades now.

The Team

• Our Precision Manufacturing team consists of two engineers:
  • One is a scooterist, who loves vintage Lambrettas and Vespas, and is a timed-served engineer, programmer and setter.
  • The other an experienced Fanuc Custom Macro B CNC, CAD/CAM programmer/setter. The use of these programs enables us to machine complex shapes, for quick tool changeover, reduced cycle times and we parameterise some of the fields in order keep the cost down.
• Part of our team is a motorcycle mechanic with a wealth of experience in building and re-building a variety of two-wheel machines.
• Our office is managed by professionals who ensure all queries, accounts and concerns are dealt with promptly.
• We have two casual staff members who help us bag the components and ensure everything is ready and despatched on time.
• Our R&D team consist of a mechanical design engineer, part time electronic engineer and an automation engineer who comes in occasionally to setup test rigs to carry out flow/pressure/humidity test. All of whom, help develop new ideas to help make carburettors to work even better than they currently do.

We love what we do and we work hard to produce the best.

How we do it

Our manufacturing team selects the highest quality raw materials.

This is then fed into one of two £250,000 multi axis high precision CNC sliding head lathes with multiple tool stations.

The machines are warmed up in a controlled environment and all the axis tooling is then clocked and other tools set before we can begin manufacture. The drills and reamers we use are from the same manufacturer that makes the drills for the watch industry in Switzerland. Clocking them precisely, and aligning it with the spindle so that all the inlet/outlet venturi, counter bores and jet holes are concentric with each other. This means that the parts are highly accurate and don’t require any additional mechanical process to remove micro burrs (a consequence  of misalignment).

All the machines are regularly maintained and checked for backlash, alignment and squareness by manufacturing test pieces and appropriate instrumentation to make sure they are accurate to tolerance and  specification. All the collets/sleeves used for work holding are periodically cleaned and are replaced before they become fatigued and worn.

We check the jets continually on setup during and after manufacture with the appropriate calibrated instrument and gauges. We section a percentage of those produced at specific intervals to inspect and ensure that each and every venturi,  chamfer and brake edge are in their  place and the required surface finish is achieved with use of projectors and digital microscopes.

The jets are made to very tight tolerances with the critical dimensions ranging from 5-10 microns. Most other machine dimensions range from 10-30microns and only a few dimensions are made to 50-100microns. (1 Micron=0.001mm)

After the jets are machined they are degreased in a seventy thousand pounds enclosed solvent degreasing plant. The process involves submersing them in solvent, with mechanical agitating, recirculation and ultrasonic processes to remove and flush any contaminant such swarf & oil deposits. The final part of the process is vapour degreasing and vacuum drying, followed by air blasting to make sure the jet holes are clear.

Once they are cleaned, samples from each batch are checked again before being prepared for  packing.

The final product is spot-checked, to ensure everything is in order while they are being counted and bagged ready for shipping.

What are we up to now

• Our R&D team are currently working on several types of OEM replacement jet including complex pilot jets.
• Some are currently on trial, carried out both by us and our professional partners on various bikes and scooters. Once these have been completed they shall be released/scheduled for manufacture. We will be rolling them out over the next few months, along with other products that we shall be adding to our range. So please keep a look out.

Thank you for taking the time to read about us.

Please take a look at our jets and put us to the test.
