Re: Honda Dio, Activa and Aviator

The kick pedal does not come up on its own after i kick,i thought it might be due to lower compression what is your take on this?.(Thats the only reason)

Cheers.

Re: Honda Dio, Activa and Aviator


I am no expert on DIO, but as a layman, the kick not recoiling back should be due to a worn spring connecting the kick, if shown to an FNG, he should just replace the defective spring.

Re: Honda Dio, Activa and Aviator

kick getting stuck doesn't mean low compression.
have the left side case opened and you will find the kick mechanism with a spring+gear kinda thingy. since most folks never have the left side (clutch side) opened and cleaned, over time the kick mechanism can get stuck. any mechanic who works on these scooters should know how to check it.
Have it cleaned, inspected and if necessary replace the required parts.

Re: Honda Dio, Activa and Aviator

Can anyone here care to reply to my post that I have made a few days back?

Re: Honda Dio, Activa and Aviator

its standard 35 watts bulb.
fuses, relay and rectifier along with battery are all located in the front.

Re: Honda Dio, Activa and Aviator

What about the rest bulbs! Indicators, brake/tail light?

I need the type of bulbs like:

Brake Light : P21/5W 12V
Indicators: PY21W 12V.

Are these the ones for Activa 125?

How does one change the rear bulbs (Tail light and indicators)? Process I mean.

Re: Honda Dio, Activa and Aviator

Since you are getting the scoot shortly, you will find info on changing the bulbs in the owners manual.
You can also ask the spares guy or mechanic to show you the bulbs if necessary and the process to change them. The headlight is a h4 type iirc and to replace the bulbs in the tail section you would need to unscrew the lens.

Re: Honda Dio, Activa and Aviator

brake lights are always standard ba15d/1157 socket.
indicators are possibly ba9s

Re: Honda Dio, Activa and Aviator

Thank you for the response.

I am looking at converting then into LED'S. Hence is my question here. Shall get more information after I get the scooter in hand.

Re: Honda Dio, Activa and Aviator

Guys I need some expert advice regarding my Honda Activa old model (2006). Since one year I am facing severe starting problem. The problem only happens at the morning when the engine is cold. It takes around 20-25 kicks to start the activa. It is used by my sister and it gets impossible for her to start it at the morning so every morning it has became my leg exercise job.
This issue has been addressed to local mechanic several times, what he does is clean the carburettor and spark plug. The scoot runs fine couple of days then the starting problem arrives again. The mechanic also changed the jet kit with original honda oem jet kit and made some money out of me.

Some observations : I have inspected the spark plug myself and it comes out clean.Mileage is superb.Primary air filter changed recently so it is almost new. (paper type)
Secondary air filter also cleaned by myself.
AFR mix is good. It has been tuned by me. No carbon deposit on spark plug. AFR is on leaner side.No mis firing seen till now.Engine not smoking. No visible white smoke.Kick starting with choke also dosnt help. It seems that the scoot has its own brain and starts only after requesting it 20-25 times.Once it get started in the morning then it runs the whole day perfectly. Whole day it starts with single self start. Even without opening the throttle single push of button is enough to start the engine.At the morning even the self start also fails to start the engine. Battery is in good condition.
One more point : The Indicator Flasher gets heated and shorted out multiple times. The indicator bulb is good, only the flasher gets shorted every time I change it.
Is there any electrical issue ??
Should I personally open up the carburettor and inspect ??
I dont have the owners manual and dont remember the recommended spark plug. In last regular servicing I insisted the mechanic to change the spark plug. The market was almost close on that day unfortunately and the spares shop gave me Bosch UR4AC and said this will work. I was in doubt and dont know the recommended spark plug model. The scoot as usual worked fine for couple of days and started with one kick at the morning then stared to fail after few days.

Kindly give me some advice guys.........

Re: Honda Dio, Activa and Aviator

first get yourself the stock plug (champion prz9hc) from Honda service center.dont use these plugs that spares guys push. I am very happy with the stock plug and the ngk equivalent cr6hsa. they costbaround 80 bucks and are good for atleast 15k km.
next get the valve clearances adjusted to spec. this in most cases fixes cold start issues.

if that doesn't sort out starting issue, it could be a bad carb tune, faulty ignition coil (try swapping with another one)
for the indicator flasher cooking out, its probably a wiring issue or short somewhere.. only on inspecting the wiring would u know what's happening.

Re: Honda Dio, Activa and Aviator

Thanks a lot for the help brother. Will get the recommended spark plug from Honda service center. Brother can you please recommend which one is the better quality product between champion and ngk. Let me check with the new spark plug if it dost help then we will try the second option for the valve clearance.Carb tuning is good I can assure you because I have been tuning bikes since school days. Throttle response is crisp and pickup is also good.I forgot to mention this in my previous post that I have already checked the Ignition coil and it shows 4 KOhms and it hasnt built up high resistance so I think thats healthy.Checked the CDI as well swapping it with another one but CDI seems to be healthy and its not the culprit.I will change the spark plug to the recommended one and report you back with the result.

Re: Honda Dio, Activa and Aviator

Btw, how is the compression when you use the kick ? wrong valve clearances will sometimes make the compression weak when you kick start it.
Both the stock champion and regular ngk (not the platinum or iridium) are good. have been running the ngk for around 12k km now and haven't had any issues.
Prior to that my Dio (2007, i.e. same as old model activa) had run on stock plugs (replaced every 12k km) for around 48k km. So yeah at 60k km my dio still runs fine without any major engine work. The only 'major' part that failed & was replaced was the RR unit around a year ago. Most other replacements were from regular wear & tear and preventive maintenance's.

Re: Honda Dio, Activa and Aviator

Its hard to explain about the compression brother. Actually I havnt cross checked it with another old model activa bcoz I dont have access to one of those. The new HET model activa and hero Pleasure that i tried kick starting has a different feel as compared to my 2006 activa.When I kick start mine , First kick feels nice and tight, then couple of 4-5 kicks goes loose, after that 1 kick goes strong and tight as if kick starting a motorcycle, then again 4-5 goes loose and then 1 goes strong and tight. Sorry bro its hard to explain lolzz

Even if we have to do the valve clearance then also changing the spark plug to recommended one is a must , so I think we should proceed from the very basic and if it dosnt help we'll advance step step.

Next week If i get time I will personally open up the carburettor and inspect it. I wont change the tuning but only inspect if the jets are not clogged then we will be sure from the carb side. Will clean the primary filter as well if I see some dust. I will change the secondary filter as well bcoz it has gone super old and is about to fall apart.

Re: Honda Dio, Activa and Aviator

i understand your explanation of the compression, it seems ok.
sometimes sticky piston rings will affect the compression.. the trick is to squirt a little(say around 3ml, which is around half the capacity of a 5ml syringe) oil in to the combustion chamber.
one way of doing it is via the vacuum pipe connection when the engine is running (on main stand ask someone to hold the throttle so it revs a bit higher than idle so it doesn't shut off) and use that oil can with the spout to connect to the vacuum pipe and squirt a bit of oil and rev the engine till you see the blue smoke vanish.
if you aren't able to do this, then you could open the spark plug hold and put in a few drops of engine oil and give it a few kicks (without ignition) and let it sit for a few minutes and then start it and hold the revs a little higher till you see any smoke vanish. clean the spark plug after this routine.

and yes you are right, go step by step in the order i mentioned. btw, where did you get hold of the carb repair kit and what were included in it ? sometimes a faulty float setup might also mess with cold starts, if its not the valve clearances..my money is on the carb float.
