Re: Honda Dio, Activa and Aviator

Well it turned out to be a lose wire, the light is working fine now

Re: Honda Dio, Activa and Aviator

some svc's might refuse to use the oil you provide, while some won't create a fuss. if you have a good rapport with them, you could easily have them use the oil of your choice.
another thing you could do is, in case the scoot hasn't racked up sufficient km, maybe you could ask them to skip the oil change.. and later on change the oil yourself or from a local mechanic with the oil of your choice.

Re: Honda Dio, Activa and Aviator

I am having too much trouble with my aviator , first the battery was fault which was replaced in warranty, still it was giving issues .Took it to electrician the relay was changed ,now again the it gives issue in self start the first time , after that the self works sometimes and sometimes doesn't (the sound it makes when battery is low).
Am not able to understand the issue

Re: Honda Dio, Activa and Aviator

Hello, I have an old Activa (2006 or 2007) and it's completely lost its peppiness, the kilometring is quite low considering the age ~25K

The problems I face are:
1. At the first start of the day the scooter usually doesn't stay running after starting unless I give it a mild throttle stimulation or use the choke and even then it'll shut off sometimes and then it needs both the choke and accelerator though having to use both is very rare.

2. The scooter throttle lags heavily for a while when using after the initial start of the day but subsequent usages the throttle is fine. Like you know, you slow down to take a corner and then get back on the throttle and you get nothing for a few seconds and then it comes back.

3. The pickup is basically dead, with a pillion I have to twist the throttle fully to get it moving and then I can roll off after its in motion.

Is there a way to make it peppy again?

Re: Honda Dio, Activa and Aviator

So I got my rear tyre changed on Honda Activa with MRF 90/100-10 METEOR M - TL. The stock tyre had to be changed after crossing 12000 kms. I wanted better grip on semi gravel roads and pothole filled roads of my area. My first choice CEAT GRIPP was not available in tubeless variant. Meteor M is a tubeless variant. The cost was Rs 1500 including GST and fitting charges. The Valve was not changed as the dealer said that there is no such problem in the valve



The problem is that now I am loosing air pressure very fast. In the morning I fill it up at 36 psi. By the time evening the pressure is about 29 psi. and by the day after in the evening it is about 9-10 psi.

Re: Honda Dio, Activa and Aviator

Your scoot needs a through inspection and service..these are the things to be checked and cleaned/replaced as required:

1. Carb - disassemble clean and retune correctly.
2. Valve clearances - check and adjust to spec
3. Open left side casing, disassemble, clean and inspect the variator rollers, drive belt, clutch shoes, springs, belt, face plate,clutch bell. replace if any of them seem to be worn out (especially the rollers if they have excessive flat spot, and the clutch shoes if their material is worn out). put them back together making sure NO grease is used on the rollers.
4. New Air filter (probably the cause of the hiccup in throttle response), and also clean the secondary air filter (sponge type located on the rhs)
5. Fresh engine oil and gear box oil
5. correct tire pressure.

so you replaced the original intended tube type tire with tubeless?? you actually have an option in appolo for a tube type tire with similar tread pattern.. i am using it, pretty good imo.
now coming to your issue, hopefully it is not a puncture.
Try to get the tubeless valve and see if that helps and also check around the rim if it is sealing properly. otherwise you need to put a tube in.
go back to the dealer and get it fixed.

Re: Honda Dio, Activa and Aviator

My original rear stock tyre which came with Activa, were tubeless MRF 90/100-10 Zapper, but they lasted only 12000 kms. The central groove line had literally vanished. My original front stock tyre still has life in it.
For the loss of air pressure. I had gone back to the MRF dealer and it was found that the Valve was faulty, i.e. it was leaking air from the place where the valve meets the rim. The value was replaced. Till now I have not been loosing air. So It was not a puncture.

Re: Honda Dio, Activa and Aviator

yep, the zappers at the rear do go out at around 12k km.. they are softer compounds.
these mrf meteor should last you a bit longer.
and glad that it was just a valve replacement that fixed the issue.

Re: Honda Dio, Activa and Aviator

I am not looking for long life. I am looking for better grip, more effective braking and more stability in wet conditions. I do not mind changing tyres frequently as long as these are met. The dealer informed me that the MRF Meteore that I have installed will give me better grip as compared to the MRF Zapper that I had. I wanted a soft compound rubber and not a hard compound rubber. I hope that I am not wrong in choosing MRF Meteore for this.

Re: Honda Dio, Activa and Aviator

Now, Activa 109 cc is emitting white smoke on increasing accelerator.

Earlier it was giving black smoke, but it stopped after valve seal change and valve polishing.

Please suggest if change of bore kit required or simply the change of only ring & piston may do the needful.

Can smoking be controlled by some other way ?

Can there be some other reasons for a smoking Activa ?

How to check the ignition coil , plug cap & wire (it produces yellowish feeble spark and sometimes misses as well) whether they are working okay, then spark plug gets blackened easily and the machine gets shut.

regards

Re: Honda Dio, Activa and Aviator

time to dig into the block/valves and see if they are causing the issue. sometimes just replacing the piston/rings might fix the issue, but again it's a risk and difficult for one to simply make a guess without inspecting the parts. considering the labor involved and risk.. most simply go ahead with plonking in a new block+piston and valves etc... if it is smoke with a bluish tinge that you are seeing, it is oil burning.
another thing that comes to my mind is, why not try and plonk in a new head gasket and see if that fixes the problem before going in for a top end rebuild.

Re: Honda Dio, Activa and Aviator

Thanks for the reply /suggestions.

Today, I opened the engine (DIY enthusiast, inspired & guided by [MENTION=28527]sibun[/MENTION], [MENTION=29030]Pinaki[/MENTION], [MENTION=53807]paul.1911[/MENTION], n many more) again.

Earlier, I had opened the head, polished the valves and installed new valve seals. Bike has run for around 65,000 km.

So today a next oversize ring set (0.25) was installed by hand-grinding using a 320 grit waterproof sandpaper, on the existing stock (standard size) piston assembly. Only a small gap was kept so as to just let fine streak of light to pass through the new rings (0.25) in the existing bore. Everything installed back. (older standard ring had developed gap of 2mm.)

After a test run for 15 kms, the white bluish smoke being emitted had completely vanished and the spark plug was found dry and threads had also dried up.

Now only black sooty deposit on plug was evident, which was cleaned and reinstalled.

Activa has now been tuned optimally.

Another test drive would confirm if the problem has vanished completely.

As the spark is yellowish red in the plug, next on the platter is checking up of the HT Ignition Coil & wire with plug cap. With that I suppose proper spark would be restored in the bike.

Thanks again & regards.

Re: Honda Dio, Activa and Aviator


Finally a guy who followed what we said in forum. Love your enthusiasm and labour to correct problem. All must learn from you. Other wise most are busy in changing oils and expecting wonders.

As for coil, you can check it by opening spark plug cap and testing the spark strength to body, if that is bluish and strong then your culprit is plug cap and spark plug.

Re: Honda Dio, Activa and Aviator

i would have first gone with new stock size rings, but anyway do keep an eye out and let us know how it holds up.
also maybe you could run say 20ml 2t oil to a tankful of fuel (20ml in 6 liters of fuel approx)i.e. for around 200-300 km to give it some upper cyl lubrication during run in due to the oversize rings you've plonked in.

btw, did you get oversize rings from honda spares itself or was it an aftermarket one like usha ? and how much did they cost.. a bit of details on the spares would help us.

changing oils and expecting wonders.. spot on !
btw, i still have one ngk plug remaining from the ones you sent me a few yrs ago love the quality and reliability of these ngk plugs.

Re: Honda Dio, Activa and Aviator

Hahaha good old days.

Yeah remember.

Had sent the plugs.
