Re: Honda Dio, Activa and Aviator

System G is supposedly for 4 wheelers as per the manufacturer.. System 23 is for 2/3 wheelers (and its hard to find system 23, last time i had a chat with petrol bunk owner he told me that since hardly any two wheeler guys buy it, they dont stock system 23)

Re: Honda Dio, Activa and Aviator

Yes, for half of the mentioned checks the service incharge told me that they would have to open the engine and since im not having any issues its not recommended either.
Those bastards took my scoot for a wash and stole some petrol too . And in the name of gear oil some liquid from a shabby little container was used, I was charged an exact amount for that (rs.63) however the gear oil amount was very arbitrary.
Shame :thumbdown:

Re: Honda Dio, Activa and Aviator

Some guys have been using it in their Fi/Carb bikes for quite some time and they are only pleased.

Lets see if I can get my hands on one of them bottles.

Re: Honda Dio, Activa and Aviator

Lol i was once charged around 90-100rs for the gear box oil.. and i wasnt even sure what oil that was (it was in the small plastic squeeze bottle that they use for general lubrication)
I just raised an objection but did not take it up with Honda, since I was tired (and also happy about the work carried out by the mech - rear wheel bearing change/coneset replacement) - so just paid up the bill and then had the gear oil changed at my local mech the next day(i usually keep a bottle of half litre of ep90 gear oil which costs about 100rs and lasts for 3-4 services and general lubrication on my bikes ) - for the gear oil you dont have to worry about measuring the capacity while pouring in.. since all you need to do is, fill it up till just starts to drip from the filling hole :-) (on the older dio/activa 102cc ones, the capacity is 0.12L i.e. 120ml - and its mentioned near the fill hole)

You can find System G at most BPCL bunks. Do let us know how it works out.. cost vs benefits(hopefully no loss ;-) )

Honda Activa(2013)

I am new to the 2 wheeler world with the Honda activa(2013) being my first vehicle. Would like to know how the engine(air cooled) is cooled? The engine is inside the hood and I was wondering where from the cooling air comes from.

Re: Honda Dio, Activa and Aviator

Sorry Guys, I was in delhi for few days and did not get time to read and reply. I assume your problem is not solved till now. I had also faced this same situation in the past. The issue was with the rollers in my activa for the scratching noise.

Now, talking about that noise, the cause can be either the rollers inside the variator or the belt. It can also be the clutch liners rubbing against clutch cover.
Firstly, I want to aware you about using grease in variator. This is a wrong practice. After reading many forums and watching videos on youtube om CVT transmission, i decided to experiment all three situations as under:

1. Greasing Rollers (not recommended):
Most of the A.S.C grease the rollers indside the variator after cleaning the variator with petrol. After starting my activa it feels initial smoothness which is limited to few kms till the grease is scraped out with centrifugal force. This grease which is thrown out can be picked up by the drive belt making it smooth and slippery which is not good. The left over grease inside the variator, generally in the corner areas attracts the dirt, which is again not good and gives poor ride quality.
For the inspection I had opened the variator after driving few 100kms and it was dirty just like before the service.

2. No Lubrication:
This time I had cleaned the variator and did not use any lubricant. The variator had already developed scratches and also rollers looked dull and scatched because of grase + dirt. Took some time to smoothen out the scratches.
This thing worked out good, no issues at all. Infact, after opening the variator after riding 100kms it was still clean and good.
Probably, the factory fitted variator has no lubricant inside it.

3. Lubricating Rollers using graphite powder:
There are many people who recommend this. So, this time I rubbed a pencil lead to rollers and inside the variator. this made it all smooth and shining as my variator had scratches before. Now, my activa was very smooth without any noise and smoother ride than before.
Even after riding 100kms my activa was still smooth. The variator was clean and shining. But there is a controversy for using graphite powder that the extra powder can be picked up by the drive belt to make it smooth and slippery.

The best practice is that no lubricant should be used inside the variator.

The rollers should be replaced every 10000kms. They are not expensive at all.

The gear oil (final drive oil) should be replaced every 2 years. It should not be replaced in every service, simply not required. Even after 2 years the gear oil will come out clean unless rear wheel bearing goes kaput.

Re: Honda Dio, Activa and Aviator

That's what i implied in my prev posts.. grease/lubrication not there from factory & not necessary (maybe just a wee bit like rubbing tilak on ur forehead with your finger will not do any harm)

Roller's are to be replaced only at around 20000 - 25000 kms (not sure on the exact number but its definitely not 10k km !)as per the manual. I noticed flat spots at around 28000 kms and replaced them much later. It all depends on how the scoot is ridden/maintained. And I think they cost me 350rs for a set (again can't remember the exact price will need to check the packing)
Btw.. let me try the pencil trick this time ;-) - will probably being going in for service on Tuesday

Regarding gear oil - Yep, the manual says 2 yrs or 15k km something.. but I prefer to do it every service approx 2500km, it takes hardly 2 mins to drain n refill and costs less than 30rs. Call me obsessive :-)

Re: Honda Dio, Activa and Aviator

Yes, you are correct lubrication is not necesssay.

In my activa i was not sure about flat spots but the top speed was limited to 65-70km/hr due to wornout rollers. At that time Odo reading was 41000kms and FE was drastically reduced to 30kmpl. Suprisingly, ASC never bothered to change them and unfortunately the old manual has no such information for roller replacement in maintenance schdule. My mechanic changed the rollers with hero pleasure ones which costed around 20rs per piece (edit: not sure it might be 30-40 per piece). Now my activa is easily doing 85kmph and feels relaxed.

Re: Honda Dio, Activa and Aviator

I am not sure if its in the manual but its on the workshop manual and i learnt that from a honda factory trained mech about the 'ideal' replacement intervals. (not the bossy attitudish mechs but someone who was knowledgeable and willing to share right info and not bull*hit ) - he was right in saying that 'sir, they will last a bit longer if ridden/maintained well, but ideally its recommended/safe to replace the belt and rollers around 22-25k km to restore optimal performance) and he also told me that the original rollers and drive belt were made in Japan (this is True since i remember reading about this) - but he wasn't sure about where the replacement parts were made. But they definitely cost more than 300rs for the honda..maybe cos they are still 'imported' or just that honda wants fatter profits
Surprised that the pleasures rollers cost just 20rs a piece.. that's 120rs a set.. less than half the cost! But are they of the same dimensions/weight (11grams) as a stock activa rollers?

Re: Honda Dio, Activa and Aviator

Thanks a ton Lokesh027 for the detailed information about rollers & variators.Very much appreciated.
I am out of station now. But as soon as i get to Bangalore I will ask my mechanic to remove the remaining grease, clean it up & I will say NO TO LUBRICATION as you mentioned. But how do you smoothen out the scratches on the variators?(if there are any that is).

Re: Honda Dio, Activa and Aviator

After reading few last posts, I decided to take a look at the hero Pleasure which acts as a home transport here for last 5 years (44K on ODO). Its a 2008 model and runs on same technology discussed above. Apart from being colored last year no major service are carried out afaik.

I was surprised to see that condition of air filter Probably changing for first time, OEM spark plug and broken suspension Bush

So started by changing engine oil and transmission oil to Honda 10W30 JASO MA. Is it recommended to use JASO MB in Hero ?
Parts replaced : CVT Belt and packing, Rear Break shoe, Air filter, Suspension Bush, Clutch bush (Rollers), Spark plug
Though the Original spark plug was a Champ P-RZ9HC the replacement used is a P-RZ7HC, and probably a counterfeit :/ can't do much there as i did not bought the spares earlier.
The Bike was having cold start problem on self so a Lower rated spark plug probably wont help there.

After changing the rollers the top end is much smother at 60-65 Km/h and pick up is progressive, before around 55-60 it was having hiccups. Though original Hero parts for Variator bush could not be found i choose for other branded parts which cost 240 for 6 rollers. FE is around 50s and high 40s with Oil draining period of 3K but i was surprised to see hero recommend a 6K drain period with JASO MA Oil oO. Is it wise to drain at each 6000 km ?

Here the Spark plug Condition after 40K

Re: Honda Dio, Activa and Aviator

Its better to use jaso MB oils in scooters as its best suited for dry clutch vehicles. Jaso ma is for wet clutch motorbikes

Re: Honda Dio, Activa and Aviator

The original belt is of Bando made. The same belt is shared by hero pleasure too. Btw Honda spares are way expensive. Replacement with OEM parts makes sense.

I don't remember the exact price of pleasure rollers. It could be something around Rs. 20 to 40 per piece some 2-3 years back when it was replaced. One thing I remember well that some set of aftermarket rollers costed only Rs. 40.. I think they won't last long.

The pleasure rollers are same in dimensions and its weight is 12grams (still i need to confirm this). The 12g rollers might be reason my activa feels relaxed without compromising much on torque and acceleration.

Has anyone here tried experimenting with different weight combinations of rollers.

I had used a emery paper of high grit size probably 240 to remove those scratches inside the variator. I did not remove extra material.

Welcome. Good to see that you have maintained your pleasure well by proper replacement of parts. The spark plug is a small issue P-RZ7HC is colder than P-RZ9HC. This could create problems like cold starts, more carbon deposits. Keep check on the condition of new spark plug. If required replaced with recommemded one asap.

For the engine oil, its time to switch over to semi-synthetic. Shell Advance AX7 10w40 is very good, far better than Hero or Honda oil. In Indian market we don't have much choice in Jaso MB grades, so you can use Jaso MA or MB. Just stick to the recommemded grade 10w30 (10w40 will give better protection).

Re: Honda Dio, Activa and Aviator

I was going to drain the JASO MA gear oil to refill with JASO MB but after checking with hero Maintenance guide i will let pass this time
Bike maintenance tips, bike maintenance, bikes maintenance - Hero Motocorp Ltd. It specifies SAE 10W30 SJ Grade (JASO MA)
I hope these are official tips
BTW i used OEM Honda Mineral oil SAE 10W30 and Does it recommended to drain engine oil at 6000 Km interval ?
