Re: Honda Dio, Activa and Aviator

how is hp gear oil of same grade

Re: Honda Dio, Activa and Aviator

should be good enough, and it's better you buy it from a petrol bunk since these guys always stock the genuine stuff. Just remember the grade is ep 90.
these gear oil's easily last an year in the gearbox.. but since the quantity, price and ease of replacement (not to mention, fresh oil is always better) it's always a good practice to change it every service (i.e. 2500~3000km interval).

My activa 125 suddenly making abnormal sounf

I have a activa 125. It's 1.5 year old & has clocked 9700 kms . It was running smoothly till last week. But since last week it had developed a harsh sound initially & now that sound has become unbearably loud.

Re: Honda Dio, Activa and Aviator

hello every one,

my new activa 3g is giving very low fuel average. i didnt find the actual value but it is around 30km/l.

ANY SUGGETIONS TO FIX THIS.

HOW MANY TURNS TO GET LEAN MIXTURE ON AFR FROM FULLY CLOSED POSITION.

I HAVE DONE 500KM ON ODO ONLY. SHULD I WAIT BEFORE SETTING THE AFR.

THANKS

Re: Honda Dio, Activa and Aviator

Please DO NOT meddle with the carb. And calculate mileage properly using tankful to tankful method.
Fuel economy depends on how the vehicle is used. Frequent short trips (say less than 5km) will return low FE. Normal city Fuel economy will be around 37~42kmpl and If you ride it 'hard' (always whacking open throttle to get off the line) expect lesser.

well, without a audio clip it would be impossible to pinpoint the cause. at-least a description of the area from where the sound comes from might help us assist you.
please get it checked by a mechanic. some possibilities could be damage to the drive components (clutch,springs, belt etc..) or a some nut or debris in the fan area or something under the seat (tool kit) that's rattling

Re: Honda Dio, Activa and Aviator

Hello

got these for changing.

On sunday.

Honda Dio TopUp Modification Helps

Hello this is Zee !
Just entered into modification,
Have a decently modified dio with all the graphics and a small upgrade of changing my spark plug to NGK IRIDIUM . I would like to receive any good modification suggestions for my bike to get a upgraded pickup and performance I would like to get suggestions from everyone with their experiences .This thread will be everything about HONDA DIO MODIFICATION

Re: Honda Dio, Activa and Aviator

Can anybody help me out. My friend has a honda activa around 4 years old. it would be very helpful if you can tell me a few engine oils that are suitable for the activa.

Re: Honda Dio, Activa and Aviator

Refer to this post http://www.xbhp.com/talkies/motorcyc...ml#post1250240

What's important is regular oil changes (2500~3000km) to keep the engine healthy. Don't expect miracles changing oil brands if the engine damage has already been done due to previous neglected services/oil changes.

It isn't easy sourcing parts for performance mods around here in India.
For a scoot, the parts that would be required for a basic mod would be a different variator/rollers/springs.. a change in these could possibly make the scoot a little more peppier. But again it's a trial and error.. so good luck sourcing and playing around with these parts.
More radical mods involve playing with the block/piston (big bore kits) and carb's. Again you can't parts off the shelf here in India.

My advice, leave the scoot stock and enjoy it.
if you are bent on mods, then get hold of variator rollers is different weights (but the correct size for the stock variator) and springs of different ratings, and then mix and match and try.
Now, If all this sounds greek and latin to you, leave it or go ahead and read up on this topic of rollers/springs and how they affect performance.. Here is good source on these topics:

Re: Honda Dio, Activa and Aviator

Wifey has a 2008 Activa which has a low odo reading (25xxx kms) but serviced regularly. Does duty perfectly for milk and school runs, or has been doing before the battery bug bit and bit badly. The stock battery, which was replaced by an AMCO one 4.5 years back ran w/o a hitch even though most morning starts were push button electric ones. When that finally gave up after 4 years last Sept, I got another AMCO from Haiku Honda at Indiranagar where we go for regular services. It was the so called maintenance free ones and became discharged in only 3 months! Invoked warranty but got the same battery back after 2 weeks after they did some R&D on it with identical results after 3 weeks, only this time I used it and not the wife and kick started at every opportunity.

Gave it back ti Haiku with clear instructions that I am not accepting the same piece back and also got them to check the alternator which they say is fine and was given an Amaron as back up, again a MF one. This one also gave up after about 3 weeks. The scooter runs about 30 kms a week, which has been the case pretty much throughout. Shall I try and get one of those 'non maintainence free' ones? The scooter runs fine and the experience of late has been marred only by the battery issue.

Re: Honda Dio, Activa and Aviator

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.

Re: Honda Dio, Activa and Aviator

Thank you for the detailed response. I can confirm that the battery being used is of the correct spec. I had taken the Activa to Haiku more than once and asked them to check the alternator to ensure its charging correctly, but had not known enough to ask them specifically to check the RR/ stator coil unit. Can you pls elaborate if there are any other symptoms of the RR/coil frying themselves? I mean the headlamps, indicators all work as expected.

Re: Honda Dio, Activa and Aviator

A motorcycle/scooter usually has a stator coil and RR unit (RR because mostly both the regulator and rectifier circuits are housed in the same unit). There is no 'alternator' like in a car. And any mechanic with basic knowledge will know to do the tests I mentioned above.

In my case, with a fried RR unit the battery simply went dead in 2 days (i.e. say around 10~15 starts). The headlight and indicators will work but will be dimmer.

I was a fool in that I replaced the battery without checking.. the battery (exide mf) in my scoot was around 2.5 yrs old and I wasn't using the scoot much (my dad uses it for short rides). One day he told me that the self start was not working and I thought, ok battery must have conked out (happened once earlier at a similar age of battery which was a regular exide battery). So I went to the battery shop and asked him to recharge the battery.. at the same time I was temped to replace the battery with the Amaron MF one. So I simply told him to give me a new battery Happily plugged in the new battery and went home. Two days later, Dad comes back and says 'again the self isn't working' !
Bang my head, go back to the battery guy ask him to recharge the battery and check voltage then head to my local mechanic with the recharged battery and we check the voltages and swap the rr unit from another activa and poof.. it's the rr unit that's bad.

So get the basic charging circuit checked before changing batteries. And also check the wiring/fuses for any damages/short circuits that maybe causing a current drain. If possible unplug the wiring at the various points (lights, rr unit, ignition etc) and inspect, maybe spray some wd 40 or contact cleaner and put them back together.
Maybe in your case it is some minor current drain that is causing the battery to go flat after a few days.
And i assume you do not use any aftermarket horns or lights on the scoot.

Re: Honda Dio, Activa and Aviator

Yes, complete stock. Its the wife's, meant for milk and school runs

Let me take it to Haiku and ask the clowns to check again. Is there any way I can check the RR/stator coil? Will a multimeter help?

Re: Honda Dio, Activa and Aviator

yes, all you need is a multimeter to do the checks I mentioned. Do the voltage checks I mentioned in my first reply and let me know the values. Since you mentioned the battery lasts a few days I won't be surprised if there was a slow parasitic current drain (there is a different way to check if this is happening).. But first let's start off with the multimeter measuring the voltages.
