I think that what is kept just a bit open are the air intake butterflies, not injecting fuel to the cyclinders. I obviously wrote it wrong in the initial post; my bad.... :smile2:I would be surprised if they are doing it by 'not closing the throttle 100%'. Surely the EuroRegs would not allow that. Or I should put it another way - if, like every other manufacturer, Honda has to make an abrupt and complete fuel switch off when the throttle is closed in order to pass the round-town emission tests, then they surely aren't going to be allowed to put a switch on the bike that then defeats this?
Solid rational thinking Kev. Still, I did a number of trials yesterday, solo and 2- up and still my feeling is that 3 offers more EB. It is hard to achive exact same conditions for each try, though. I have read reviews and seen video-reviews and all say what the book says, but quite exagerated in my opinion. The difference is real subbtle while the reviewers claim quite substancial difference, which I do not feel.My take is this:
The more intervention, the higher the numbers, so:
3 is least power ie max intervention from standard power
3 is least engine braking ie max intervention from normal engine braking
6 is max traction control ie max intervention from direct drive
Engine Braking set to 1 is absolutely the least braking effect. I've been playing around with it and it's definitely 1-least, 3-most. It's a handy feature to have, I quite like being able to choose.You are right Mike, the manual says 1 is the strongest. But I also have the feeling it is vice versa, like Scorch Dugan said.
It would be hard to be a typo, but you never know. I will also do some more throrough checking and come back.
I think having more engine braking helps on dirt, to be able to let the engine help you going downhill without using too much of the disc brakes. Think how much harder it would be with your bike in neutral going downhill and using your disc brakes only.Let's see it from another perspective:
I do not do dirt at all, so the guys that do may help here; In gravel or dirt, do you need stronger engine brake or not?
In the manual ATAS, on GRAVEL mode, the EB is set to 3, so maybe we can draw some conclusion aside our subjective observations.
