Every motorcycle is different, as they are all just machines, built to acceptable tolerance levels by the manufacturers and built to satisfy stringent worldwide emission laws. Although the manufacturers build tolerances are good, they are not perfect, and so ten identical bikes will actually put out ten different power outputs. Here at Custom Tuning Aberdeen, we offer a truly bespoke tuning service to get the most out of your individual bike.
For the perfect ignition burn, you need a ratio of 1 part fuel to 13.2 parts air for most bikes. Very few bikes are actually running this exact ratio straight out of the factory, and so we can tune it to a far better ratio for you. If you fit a hi-flow air filter (eg K & N) or an aftermarket exhaust, it can cause your bike to run lean which means too much air going in for the amount of fuel, so the ignition is not as great as it could be, as the ratio has changed. An ECU Remap or a power commander will remedy this, and give you greater power and torque, and better ride ability.
Our full custom remap is carried out on our state of the art dyno, and the work we do varies model to model. Most modern bikes are very restricted by the manufacturer in order to pass Euro4 emissions tests. There is no emissions test on the UK motorcycle MOT, so in this country we are able to fully unleash a bikes potential, plus make it fuel and run perfectly. It’s unbelievable how badly a lot of bikes run straight out of the factory. Snatchy throttles, limited power, poor fuelling, and poor fuel economy are pretty much par for the course on new bikes. If your bike has an aftermarket exhaust fitted, the custom remap will benefit you even more, as the bike will have much more air flow than a standard restrictive exhaust, and so the potential for improvement is greater. Some bikes are restricted in the first 3 gears from the factory, so we remove the restrictions, as well as having badly mapped throttles which results in a very snatchy throttle that is hard to control at slow and medium speeds. We make many more changes too, but these are the main ones, and the ones which are the easiest to explain. This work takes roughly half a day.
