No, I havent replace the pulleys. And the sliders have given good results with faster acceleration and lower rpm at 90-100 km / hHistory first...
I see you fitted new cylinder and piston recently fitted.
Did you ever replace the worn pulleys?
If not then you are not getting best available from power you already have.
Dr.Pulley sliders won't increase your power, but along with other new CVT parts may possibly improve response times.
(Pre-2007 Burgmans are known to "use" some engine oil - Increasing performance + revs will likely make that situation worse).
1. Sliders are changedTo get more power from a 400cc single requires a LOT of work.
Sometimes its a lot easier to gain performance in other ways, playing with items like:
1. Slider weights.
2. Contra spring.
3. Overall weight of bike and rider.
4. Retuning of fuel and ignition.
The best and probably much less expensive way to get a faster Burgman is to trade your 400 Burgman in for a 650 Burgman. That said, look into making the engine sensors lie to the motor computer by inserting resistors in the sensor wiring so it thinks the air and coolant are cooler than they are which would make the fuel mix richer.No, I havent replace the pulleys.

Oil consumption is now at a normal level after the replacement of the piston and cylinder. I have also installed an oil catch can that the crankcase ventilation passes and that will catch the oil mist, but I have not yet received any oil in it.
What I am looking for is if there is any method to increase the engine power. Is it possible to make changes to the control system?
I agree with this. I have a (carbureted) DR650 thumper and while acceleration is a little better and it has more "grunt" (and I know many differences between the two), top speed with that engine is virtually the same as the 400. That tells me they're wringing out about all the power realistically possible....
The motor in stock form produces a about 1 1/3 HP per cubic inch. I don't think there is that much more to be had from the Burgman 400 and still have a reliable long lived motor.
