The Honda PCX / Forza / ADV150 / SH Forums

EasyRider, if correctly understood my message, then a smooth start with the Idle Stop system is comparable or even smaller than the push that gets the engine by increasing the speed of the scooter. Use the Idle Stop system has never doubted her safety for the life of the engine. Smooth run like hybrid cars, completely silently and smoothly. The beginning of the motion of the scooter occurs instantly, as if the engine is not stifled.
In any case, to give an expert opinion on this issue, it is necessary to have tests for a long time.

You are very right.. Time will tell. It may very well work out , but I am concerned about Murphys Law. Most new advances work fine in the beginning , but like you said the constant heat soaking during stops can affect pintle cleaning and take a measure on the engine as a whole. On the flip the engine will have less RPMS over the life of the engine. Dont know yet how that will affect the life. I personally am old school and like an engine purring under my ass and feel more confident when I twist the throttle there will be less chance of any surprises.Motorcycles tend to vibrate more and bounce more and that will affect terminals , electronics and sensors moreso than a smooth riding car.Like you stated however time will tell.

I think Start/ Stop has potential in drag racing, whereby a CTDS (Christmas Tree Detection System) sensor will detect the onset of the Christmas tree's sequence and trigger full bore acceleration.

This same feature could be adapted to a FBTO-TLDS (Full Bore Take Off - Traffic Light Detection System) to detect traffic light change to green, but of course people running a red light may possibly make the Full- Bore feature more exciting than desired.

Also, unexpected FBTO-TLDS activation may be a surprise to an inattentive PCX rider, which is probably why Honda insists on having the hump in the seat. A no-cost "free" and valuable secondary feature for the TLDS would be designated the PCX- IPES (Inattentive Passenger Ejection System).

Don't worry about it !! It's just "better", the techies guarantee it ...... simply a matter of science and simply being open to accept progress and change and - well, a few personal sacrifices while the initial system bugs are worked out.

..... where's my next beer ?

I don't use idle stop but perhaps it's good for long infrequent pauses when caught in traffic jams or not able to filter. In the UK and esp. London, it's rare to stop for more than a minute or so so why bother.

In large cities such as Moscow road lanes wide and the traffic going between the rows, so stops a little. But if you count commuting and stop 3-4 a day for 0.5-1 minute per month will be enough.
With the system Idle Stop funny look at the drivers who are surprised that you are only standing at a traffic light with a stalled engine quieter all and instantly flew forward when the light turns green the signal.

personal sacrifices= $
bugs are worked out = $
the techies guarantee it = Titanic

Its all good !!! LOL

I think the technology is beneficial to owners, especially the way Honda did it with the manual option so the driver can turn it on/off as it makes sense.

Over-all it's a net-sum-loss for most scooter owners since they idle so efficiently, which is also the case for most vehicle engines--especially considering the electronics they have to power. An owner will almost never recoup the cost of the technology in fuel savings. If one considers Total Cost of Ownership, taking into consideration the additional wear on the engine, battery, electronics in general, plus initial purchase cost, it's a huge loss.

The benefit to owners would be best realized by changing the starting system to the start-stop components (for economy of scale cost reduction) and leaving the rest of the system manually activated in my opinion. This would reduce engine wear, technology costs, etc.

Does anyone have the description of the start/stop system from the manual? in my manual the system isn't covered ( US manual)
Thanks in advance!

Save your breath. Common sense and practicalities are lost on them

If you have nothing intellectual nor funny to add, you could stop trolling the forum. There's no issue with you having a differing opinion--that's how we tend to learn things in many cases, but continuing to post nonsensical comments without even an attempt at humor is counter-productive.

I thought it was in the U.S. manual, but here's a link regardless. See page 52-60.

I don't know if anyone mentioned this, I didn't read the whole thread but I explain why my stop idle doesn't work in my long term video review I posted yesterday. I once left the bike on and it completely drained the battery. For some reason, after that, the stop engine light would not work. When I tried replacing the battery with a new one, it worked again. I went back to the old battery because it worked fine and I didn't use the stop engine. That was two years ago. Battery still working fine.

There are some that are outright silly buggers.Pay them no mind.

When I first got the bike I used start stop feature , but when the winter came and had to commute in the dark, the green light on the dash would irritate me so I turned the feature off. I could of stuck some tape over the light but I am also aware that I want the bike to last me circa 50,000 miles so anything to extend engine life the better. Peace out

This season, the idling system does not work so clearly and much less than last season. Charged the battery after the winter, but the idling still does not turn off as often as last season, may have become a little ride or less long stops and the PCX engine does not have time to warm up.

Use mine all the time.

The bike doesn't use a starter motor to fire up. Hence why it's near silent when it fires. If memory serves correctly.

It is nice sitting in complete silence during red light waits. I've had my car for 7 years on a single battery with stop start. Obviously you need to use the bike enough to charge the battery.

In terms of engine wear. I doubt anyone would actually notice given the length of time most people own scooters for?

I'm getting over 140mpg and I've fitted an aftermarket screen. I wouldn't have been able to add after market idle stop if it wasn't fitted at factory / designed for it.

So although I agree. An underseat light and better seat is useful. They can all be added if you wanted.

I love mine!

Could it be that a thermostat fault in the engine cooling system could affect the idling system? The engine is constantly cold and therefore the system does not work. This season, the idling system worked very little, compared to last year, the mode of operation and the route of movement are the same. Battery in good condition. Does the PCX have a thermostat in the cooling system?

The idle-stop feature is dependant on battery condition but is far from linear on volts across a small range - so as the battery ages the idle-stop measuring algorithm may decide to disable idle-stop more often to play safe. According to a UK idle-stop graph I saw in the UK service manual amendment.
I do not believe idle-stop is fitted to US bikes so no, the manual would not mention it.
'I once left the bike on and it completely drained the battery' < with idle-stop enabled and the engine off (no battery charging) the lights stay on, so if you are stopped for long periods the battery will drain and idle-stop may then stop working or over time the battery may suffer.
