ENGINE—PERFORMANCE KIT (EFI inc GT) EFI and CONTINENTAL GT PERFORMANCE KIT
EFI
The graph above shows the BHP and the graph below shows the torque of a standard 500 EFI and the same bike with the 90601 kit fitted.
There is over 32% increase in BHP while the torque is impressive throughout the rev range.
We have spent several years developing and proving the 500 EFI engine. A lot of what we have learnt transfers straight over to the new Continental GT although we have spent considerable time developing these parts further, (It was the GT that pushed us into purchasing our own dynamometer, a “Dynojet 250i” with load control). We now have a fully proved and tested basic performance package which can be fitted in stages or as one complete kit. The standard back wheel horsepower figures are not consistent between models and also not very high in relation to expectations. For the purpose of comparing we will give you average actual percentage increases that we have achieved at the back wheel.
FITMENT GUIDE
E5 + G5 ELECTRA EFI C5 CLASSIC EFI B5 EFI
CONTINENTAL GT 535cc GT
We have 2 packages for the 500 EFI engines and 1 package for the 535 GT engine. Amongst other smaller parts, all kits include a replacement K&N
air filter, performance valve kit, cam and pushrod set and the all important Dynojet Power Commander. The 500 kit has an option of a 535 big-bore conversion, these parts are shown and described below and on the opposite page. As there are a few choices of freer flowing silencers these are not included and must be purchased separately if you do not already have one fitted. Please see our exhaust section of this catalogue to see the selection.
90601 £715.00 500 EFI 90602 £1125.00 500 EFI but with 535cc big bore kit 90605 £715.00 535 GT
DYNOJET POWER COMMANDER
The first step to tuning your Bullet is to fine tune the fuel to air mixture that the engine receives along with the ignition timing. With the older carburettor models this is fairly easy but with the EFI models it is all controlled by a factory set “ECU” (engine control unit). Even with a standard engine we have found that the mixture ratio and ignition timing is not always perfect and can not be adjusted. In conjunction with Dynojet UK we have developed a “Power Commander 5 System”. This works by piggy backing the existing ECU and makes changes to the existing settings to deliver the optimum ratio of fuel and air and ignition timing at any given throttle position and engine revs. Whilst this can offer some improvements on a standard model, it is essential when tuning the engine with different silencers and air filters etc.

The graph above shows the BHP and the graph below shows the torque of a standard 535 GT and the same bike with the 90605 kit fitted.
There is over 40% increase in BHP on this bike and again the torque is impressive throughout the rev range.
