Fully trained engineers carefully assemble all our engines in a purpose-built, dust-free room with no machine tools present. This ensures that the engine components and the partly assembled engines are not contaminated.
We rebuild engines to be used, be reliable and give thousands of trouble-free miles. In addition, we guarantee the engine for a full 12 months of unlimited mileage.
HOW MUCH DOES IT COST?
Before we commence the rebuild on your engine, we inspect it for wear and damage. An estimate is then compiled, listing all new parts, engineering work and repairs required. We include a list of options such as exterior cosmetics and other valuable modifications & options, for example, Needle Roller bearing conversion, dynamic balancing, lead-free conversion and tuning options.
HOW TO START THE REBUILD
If you are sending a complete engine, you will need to build the engine into a substantial wooden box. Then contact us with the weight and dimensions of the package, and we can organise the collection. We will use the same box to return the rebuilt engine to you.
BRING THE WHOLE BIKE
We offer a complete service in which we will remove the engine, do a complete rebuild and refit the engine back to the chassis. We would then put the bike on the rolling road and set up the ignition timing and carburation.
