Re: Honda Dio, Activa and Aviator

Changed oil. Used regular Honda oil. Bought a can of servo gear oil.
Changed both myself. Hardly took 10 min.

Recently got to know that no mechanic ever changed gear oil in my 50K run Activa. Ran through all service invoices. No where I could find gear oil change. Hence decided to do fluid change on my own from now on.

Gear oil was thick black paste when draining. Felt bad and cheated. Now will be draining gear oil again after 500 odd kms, just to flush out all debris which had been accumulated over years.

Re: Honda Dio, Activa and Aviator

Any reduction in harshness? Also, why did you not find a good local mechanic instead of putting up with Honda service centers after free service was over?

Re: HeroHonda Pleasure 07

Hello there, was getting mild sound on decelerating in city limits and early morning screech when pulling (10 the year of service and 62K Odo).
Decided to disassemble the Clutch and Variator assembly.
Last time Variator assembly serviced, that was 3 years/18K km ago with rollers replaced. This time rollers have premature EOL with flat sides and Variator housing also have visible worn out grooves. So decided to change both as a set. Clutch housing been opened with little prying and greased the bearings. Clutch shoes still in good shape. Kick leaver have recently sounded clunky but pinion looks good but dry. So Kick pinion got serviced with bearing grease. Lastly oiled the bendix drive of Starter assembly. There was some confusion in Hero ASS over price of spare parts, as they were charging 10% more over MRP in the name of GST. Escalated to higher authority and refunded the overcharged amount with slight hesitation like over charging is normal for older stock. Funny experience. Total setback count 375+(53x6)+ 200 = 900
and a whole total of 5 hours

Re: Honda Dio, Activa and Aviator

A lot of harshness while accelerating is gone [emoji7]

It’s used by my parents and you know.... they get cheated easily.
I was using it recently and found many things un hondaish and started fixing one at a time.

Engine flush and gear box flush on cards after 500 km. Will throw in a new air filter too.

Re: Honda Dio, Activa and Aviator

Hey, thanks. and sorry for replying after so long. I didnt do much mods after that, but just changed the clutch belt, clutch shoe and springs to OEM ones. but now my dio does 100-105. I only have aftermarket air filter and tuned Carburetor. Ive Clocked 22k kilometers now and It's pickup is still better than other scooters in market.(including access125 and excluding activa 12). I've been planning to do porting of valves. lets see how it goes.

Re: HeroHonda Pleasure 07

Thank You man, but I don't think the Pulley type of roller/slider can be sourced here but thanks for the heads up.

Re: HeroHonda Pleasure 07

just stick to the stock rollers and make sure you get the clutch side opened every service (usually every 3k km) and cleaned out and put back together.
it's mostly the lack of maintenance that causes more wear and tear and almost no svc will do this work during a regular service.. I've always had the clutch side casing removed and dismantled every part in there, cleaned and put back with a bit of grease on the starter bendix (don't put grease on the rollers), the rear sheave(which has the big spring). and just for a peace of mind replace the gear oil too every service or worst case once a year and use good quality gear oil from a brand such as castrol, mak spirol etc.. avoid the ones sold in loose/pouches (it hardly takes in 120ml and is a 2 minute job)
this is just my experience on my dio that's now clocked close to 70k km in 11yrs and i've replaced the rollers once just as a preventive maintenance (i think at 45k km).. of course you will notice a bit of a flat spot but that did not cause any pickup/acceleration issues, so keep an eye out and replace as required. i had also replaced the clutch shoes and springs around 55k km iirc , again as a preventive maintenance. .the old parts i throw into my parts bin as spares.

Re: Honda Dio, Activa and Aviator

good luck trying to find those specs i haven't seen them specified anywhere on the manual.
but if my memory serves me right, i think the ones on the old activa/dio (102cc) were 11g (i think i saw something like 11g printed on the packet when i bought the rollers). i haven't really paid much attention to the parts on the later models .. i own the old 102cc model dio and this was also sold as the scv lead in the uk and parts manual/specs are available if you do a bit of searching on the internet.

also am not sure the exact changes between het 2013 and 2015.. changes if any should be minor and mostly cosmetic. what was more significant was with the het initially they bought in offset crank and thinner rings to reduce friction.. later iteration of the het based models did not have any significant mechanical changes i guess.

Re: Honda Dio, Activa and Aviator

Hi,

I recently purchased a activa 125 bs4 model, i am facing vibration @ 55 - 60 kmph. After crossing 60 kmph vibration gone automatically.
what is the reason?

Re: Honda Dio, Activa and Aviator

102cc is also commonly referred to as the 100cc activa/dio.. both share same engine.
i think the roller dimensions are 16x13 on the 102 cc dio. this is from my digging around various manuals/scooter parts sites.. i haven't physically measured the size or weight. i think i have a set of used rollers lying around, ill see if i can measure the dimensions and post that info here in a day or two.

Re: Honda Dio, Activa and Aviator

I recently rode the latest model of Suzuki Access . Found that its suspension is much more better than Activa's in soaking up bumps and potholes on the road. Further unlike Activa, which feels like there is an iron rod in the rear and not a suspension assembly, the Suzuki Access also has a better handling characterstics overall as compared to Activa. I certainly hope that Honda improves upon ride and handling of Activa. But Honda has been know to lag its competitors in terms of features offered on the scooter as well as ride and handling. This has been true in case of cars and two-wheelers. Unless there is a competitor product which offers a particular feature, Honda will not introduce that particular set of feature.

Re: Honda Dio, Activa and Aviator

suzuki access engine is not strong as of an activa,it needs reboring prior to an activa

Re: Honda Dio, Activa and Aviator

Honda Scooters' rear suspension have always been the Achilles' Heel. One who's ridden the Dio in special would know how hard the suspension is. The dated tube type front suspension is hard as rock and the rear is equally tormenting. Though people have changed the rear shock of Dio/Activa to that of Wego (disambiguation noted). As you've rightly stated, Suzuki isn't any better compared to Honda in the suspension department, but they offer good damping though going over a hard bump, one won't feel big a difference between both.

Low speed undulations are very well damped, and the overall front end feedback is positive in the Suzuki when compared to other scooters. TVS offers better comfort when it comes to both H and S and have a decently sprung setup.

Cheers!

Re: Honda Dio, Activa and Aviator

I found some good info on the roller weights from an oem supplier (skf) who are well known in the bearings market.
Parts

The 102 cc models do indeed have 11g roller (i also remember seeing 11g printed on the original part packaging when i replaced it)

The later model from around 2009 onwards i.e. 110cc ones have the 17.5g roller . Later the 110cc became the 'HET', with essentially the same displacement but improvements as i mentioned earlier. So the activa 110cc het (currently 5g for 2018 ) still probably continues to use the same 17.5g roller.


I stumbled upon this link from skf.. pretty useful if you want to search for bearings, coneset for your vehicles.
