First of all my regards Sid ji.
Sorry I'm quoting an old post but couldn't find anything more perfect to explain my problem.
As you explain in your post my battery's voltage is shooting up to around 16 volts.(on idle itself)
My bike's battery isn't supporting my button start. Showing 13.7 v but on pressing start, goes down to 2/4 v.
I'm on a service battery which I procured after requesting the Amaron service guy.

Also please take into consideration that I won't be able to perform 'the rr unit swap' & simply check.
Will shift to pm later to explain further

This isn't normal. You need to get the charging system checked to ensure the battery is being charged. One of the two components that could go bad are the stator coil and the regulator+rectifier unit.
And remember if you let a good battery run flat a few times, it will eventually kill the battery (i.e. not hold charge as designed to).. a failure of one of these parts(stator or rr unit) will cause the battery to go flat. So you need to find the root cause rather than simply swapping batteries. And I hope the battery you are using is of the correct rating.. if it's an old model (i.e. 102cc first gen) then the battery should be a 12V 5Ah .. the latter models started coming with a lower capacity battery.

Now how does one check the charging system:
1. A Good battery should read at-least 12.7 V approx (i.e. just the battery without any connections)
2. Start the scoot and at idle measure the voltage. It should go up to around 13 V
3. Next hold the throttle half way and measure voltage, The voltage should increase by around 1~1.5V (i.e. should now be 14-14.5V)

If you don't see the voltages increasing then it could be a faulty rr unit or stator coil. also note that too much increase in voltages(say it shoots up to 16V) also indicates a fault. An easier way to rule out a faulty component is by swapping it with a known good one where ever possible.

I've had the RR unit go bad on my 2007 Dio (after 8.5 yrs) and I confirmed it by swapping it from another Activa at my local mechanic. The RR unit will cost around Rs.550 and is easy to replace, the stator coil might require more labor.

I have a few questions I wanted to ask, if anyone has any views on them please feel free to answer.
Firstly, the engine, an additional foot rest and side stand are all on the left side, does that make the scooter left side heavy and affect balance of the scooter? If so is there any way to balance the scooter properly, like adding a right side foot rest(seeing they contain metal parts)?
Secondly, about mods, can I add a windshield? There isn't exactly any place to attach it... What about extra led lights on the front? Does adding the 'inner box' or 'glove box' on the scooter hurt your knees?
Thirdly, just out of curiosity, is there any performance mods?
edit:Its a Honda Activa 4g BTW.
Thanks in advance

Man, did you change the battery in your Activa. I had the same stalling issue due to weak battery. It fixed after changing to a new one.

Update: After spending too much time, had to sell activa it was stalling like 4-5 times in traffic and honda svc were not able to solve things.

Bought yamaha ray zr (disc variant )

Hi,



I concur with the Sd1 views,Its a very good practice and you should continue. Although I recommend you to keep it for 2-2.5Min as opposed to 1min as discussed in other threads the Engine Oil takes about 2 odd min to reach the heads and hence recommended to wait for 2-2.5 min.

Also about the kick start,Its also a very very good practice and will not strain the battery on a cold start.

I do both myself and recommend it !

Regards.

Guys, I just bought a used April-2014 manufactured Honda Activa I HET model with 3500 KMs on the ODO. This is for my wife and my ride is a Dream Yuga which has been serving me well for the past 5 years. Since this is my first experience riding an auto gear scooter I wanted to check if the mild woosh/whiny noise coming from transmission when closing the throttle at higher speeds like 30 km/hr and above is normal for honda scooters.

sorry buddy, i can't help you further without actually listening to the sound. a lot of folks here keep complaining about different raga's, tunes, tick-tocks and it's almost impossible to say if it's a normal or abnormal sound. Please ride another activa and see if you notice similar sounds.

Thanks for the reply. I will get the nuts/bolts tightened. But the exhaust noise you mentioned happens when the engine is off right? I know that sound but I was actually worried about engine noise which can only be heard when the engine is very hot and running. If I switch off the engine for 5 minutes then start, the noise is gone. The noise is a much lower note tick sound than exhaust one. More like tock than tick!
Fuel economy I got between the last 2 fuel stops is 52 kmpl. I am slightly surprised even though after buying it I was expecting 60 kmpl as company mentioned! Then came the shock of course. But after the last check I am quite happy with this.
Thanks

For the vibrations, get the nuts/bolts tightened (panels/floorboard/side stand).
The tik-tik-tik sound is normal and your svc mechanic is right. It's the sound of metal (exhaust/catcon) contracting. Occurs on almost every scooter motorcycle especially when they are new. Nothing to worry.
The fuel economy you are getting is perfect. Enjoy riding it and do not worry much or try to fiddle with something unnecessarily.

But last one month I have noticed buzzy floor board vibrations after 50kmph. The vibrations have increased last few days due to hot weather conditions I think. Also there is a tick tick noise coming from the engine if it gets hot after riding for a while. I told this at the service centre but they said its normal!
