I supply and use exclusively Dynojet products for EFI tuning – either the Power Commander 5 in conjunction with a Dynojet 250i dynamometer or the Power Vision flash tuner for either narrow or wide band auto tune sessions. Both of these options provide an individual custom built fuel and timing map which is essential for any performance built engine. Cylinder head work creates additional airflow which in turn demands additional fuel in order to run at maximum efficiency and operating temperature. This is not just a one size fits all canned software download as you are sold at the dealers, this is a map designed in real time on the dyno or on the road whilst monitoring and correcting the air/fuel ratio of your engine so that you get the very best out of it. If you have a dealer supplied SEPST tuner then that also can be tuned. I can provide the full custom mapping service that the dealerships cannot. The final tune can make a substantial difference to the power output and engine life. At the very best you are losing out on power from your new build and the worst case is potential engine damage due to overheating. Engines have been destroyed by running without air/fuel ratio correction after porting work. Carburated bikes can also be dyno tuned. Contact me for more information.
Fast Lane 95, 103, 100, 110 and 117 inch Big Bore kits - Bigger IS Better!
It’s a well established fact that the foundation of any performance project is always the available capacity of the engine. With greater cylinder capacity comes more available compression which when combined with performance camshafts and improved gas flow through the cylinder heads results in a serious performance increase. The early Twin Cam 88 engines can be increased to 95 cubic inches by boring the stock cylinders or 100 cubic inches by using the new S & S steel lined four inch bore cylinder kit which simply drops into the stock 1999 – 2006 stock crankcases. Similarly the Screamin Eagle 110 and 117 inch bolt on kits allow massive increases in displacement for the 2007 onwards 96 and 103 inch engines without any crank case boring. There’s great news for CVO owners as well. These underpowered stock 110 inch engines can now grow to 117 inches – this is potentially a huge power increase once mated with matching cams and head work. See the Power Packages page further on for various performance and fitting options.
