Kart Engine Rebuild & Chassis Service

Your engine is in the hands of people who know every part inside it. We never rebuild on guesswork: before any work begins, you know exactly what your engine needs and what it will cost.

Kart engine service

How your engine service works:

1. Inspection: We strip the engine, measure all relevant parts and document their condition.
2. Findings: You learn what needs rebuilding now and what is starting to wear. That way you can plan your next rebuild instead of being caught out by a failure.
3. Cost estimate: You receive a quote for the work required.
4. Your decision: We only rebuild your engine once you approve, exactly as ordered.
5. Return shipping: Every engine is cleaned and safely packed before it goes back to you, together with a data sheet showing the key technical data and settings.

Documentation and root-cause analysis

Every rebuild includes technical documentation. We record existing damage and irregularities. If an engine has failed, we look specifically for the cause so the same damage doesn't happen again.

Genuine parts from stock

For the engines in our range, around 95 % of parts are in stock. That's why your engine is usually back with you within a few days. We use only genuine spare parts and high-quality branded products. Every part is inspected on arrival, before it goes into stock or into your engine.

Optimisation and tuning

Race engines are built for performance from the factory. Finding extra tenths takes experience, patience and precise measurement. What counts in the end is not just peak power but also driveability, reliability, a power curve that suits the track, and compliance with the regulations.

Discretion

Many of our customers race. What's inside their engine and how it's set up stays with us. We never disclose customer names or set-ups.

Chassis service

Set-up and baseline settings

A properly set-up chassis is the foundation of fast lap times. Modern chassis react sensitively to small inaccuracies, and the tyres' temperature window keeps getting narrower. A chassis that overworks its tyres loses pace quickly. Only a cleanly built, well-balanced chassis delivers consistently fast laps.

Inspection and repair

A light knock or a touch with another kart can be enough to bend a frame. Our workshop has specialist tools, measuring jigs and factory specifications. We use them to check and straighten chassis without compromising their performance.

Personal advice

You'll talk to a real person who knows the parts. For difficult technical questions, the boss advises you himself. For complex topics, email us with photos so we can answer your question in detail.

Sending in your engine or chassis

Please call or email us before sending anything, so we can prepare your order. If you are outside the EU (for example in the UK or USA), please contact us first about shipping and customs.
