The art of the engine tuner
Tuning and building high performance motorcycle engines is a matter of combining and balancing many complex factors, together with the application of a great deal of knowledge, experience and expertise.
Modern motorcycle engines in stock form are highly-advanced achievements of automotive engineering. Rev ceilings that were once confined to racing engines have now become standard and are covered by warranty with 10k service schedules!
Because of this, the work of the engine tuner is now often a matter of refinement – altering characteristics to suit specific applications – rather than simply chasing massive output gains.
The engine tuning and development work we do at JHS Racing commonly begins with the use of our dynamometer to accurately measure the engine’s output. We then interpret this information, in combination with our knowledge and experience of the techniques that are available to improve the engine’s performance to fulfil the customer’s requirements.
Of course we are known for specialising in certain engines – notably Suzuki’s SFV650 twin and the Triumph 675 triple – and renowned for our accumulated expertise, and proven success, with optimising these powerplants for track and racing applications. But we can undertake tuning and development work on just about any make and size of engine or type of machine.
Overcoming the limits to performance
Whilst modern stock engines have attained extraordinary levels of performance and durability they are, nonetheless, still constrained by inherent limitations: factors such as manufacturing cost and the practicalities of production, as well as the rigorous demands of legislative compliance, all impose limits upon achievable performance. So, If you’re prepared to expend time, effort, and make an investment in superior quality components, these engines still offer scope for improvement in the hands of a skilled engine tuner.
