Default Honda Unicorn Help

Hi All,

I own a Honda unicorn, which is of five months old. I need one help regarding the vibrations coming from this bike. I used to travel almost 60Kms/day as a part of my daily travel to office and back. I cruise on this bike from 50-60Km/hr. The problem pop up when the speed exceeds 45Km/Hr. A slight amount of vibrations start coming up from the back break pedal and from the petrol tank, These vibrations remains there as long as the speed is above 45Km/Hr or the RPM is above 3500. When I took it to the dealer he says that these vibrations are normal and keep away your foot from the back break pedal to avoid these vibration reaching in to your body (I think once the seat start the vibration, then he may suggest that don't sit on the bike to avoid vibration reaching to the body). If I cant keep my leg over the back break pedal on the speed above 45Km/Hr then how will I manage in case of emergency stop? There are two different dealers are here in my native place, Both the dealer have the same answer to this issue, "Normal vibrations". Because of these vibrations and long distance travel my leg started getting small amount of pain. It would be great if any one of you can help me sort out this issue. Even if these vibrations are there the, I really love the bike. The bike is so smooth that you won't really feel any kind of discomfort if you travel at speeds 40Kms or so. If I can rectify this vibration problem then this bike would be great bike for me which satisfies all my requirements.

Thanks and Regards
Manoj

Default Rubber Spacers

[quote=Manoj]Hi All,

Hi!

There are rubber spacers below the tank to reduce Vibration check if they are worn-out, in general service the remove and check the rubbers, there are chances that the rubber spacers is missing or worn-out and about the back breaks check if the break leaver is too close to the foot rest or in contact with it. you can get this checked at any local meck or do it yourself.

Hi Hellcat,

Thanks for your reply, I will check these things, but how the foot rest can be in contact with the back break pedal? Or is there any rubber bush is there in between these two, During the first few hundred Kms the vibrations from the break pedal was not there, Or since because of the speed restriction, I may not have noticed. The vibrations start coming after the second service (>3000 Kms). As there were no speed restriction, I used to travel bit fast, I remember, the dealer saying that all the parts in this bike is kept using rubber bushes. So is there any possibility of having a worn out in the rubber bush between the break pedal and the frame of the bike?

Thanks and Regards
Manoj

Hi HellCat,

Thanks for the information. I talked to HONDA people in Bangalore. Regarding the petrol tank vibration: As per the bike design the engine in the bike is centrally mounted and there is no underneath support for the engine. The engine is like a hanging element on the bike frame. So once the engine starts vibrating these vibrations will pass on to the bike frame and these vibrations will get reflected in the petrol tank. As per their reply this is not a problem and it can not be rectified too. The person whom I have talked to itself have the same problem in his own bike. so no other way, but to suffer, Then regarding the break pedal vibration issue he will get back to me...

Thanks for the information hellcat.

Ok so that's all he has to say a design flaw by Honda I was in an opinion that Honda makes good quality bikes....but I guess that is only for the other market and not for India, i guess since its India its that Chalta hai attitude like the other manufactures in India. I think u should go to the bottom of this problem bug the hell out of the Honda engineers till they solve your problem....dont let go with the chalta hai attitude like every body does. Send them mails tell them ull go to the consumer court if needed. Its a five month old bike if you are getting all kind of vibration imagine the condition of the bike may be after a year or so.

the engine is fitted using rubber bushes.so if these bushes are in order no(not too much) engine vibration should reach the body.

i have used it for abt 9 months and i dont feel wht u have felt...it feels as vibration free as the best bike thats available in the market...unless and until ur vibration pblm is specific...

Tank vibration is there but negligible...u r getting too much concerned ...i think..


I havent experienced any vibrations in the brakes...i can assure u that...

all the best..

Hurry Home

I have been in to the HONDA Showroom, They again said that these engine vibrations are normal. What ever the slight body vibrations are passed on to the back break pedal too. Nothing to worry. They allowed me to test drive another two three bikes which are parked over there. All of them have these same vibrations in their petrol tank and back break pedal. So I think this is normal and I have taken it too seriously...

Change the oil gasket and check. I think that would be the reason.

Open the head and change the cylinder head gastket. That will solve the issue.

Is your Unicorn 2005 or 2006 model?

Please do the following(as I also have a 2005 Unicorn and I experienced the very same problem last month and has rectified it absolutely). The reason for this oil leak is a worn out valve cover rubber packing which allow the oil sprayed by the timing chain to leak through it. THIS IS NOT A LEAK THROUGH THE CYLINDER HEAD GASKET.

1.Loosen the valve cover bolts(2 numbers) located on the top of the valve cover. This can be easily done after removing the fuel tank by loosening the single bolt located below the seat(mind you, there is absolutely no need to open the cylinder head or change gasket)

2.Replace the rubber packing with a new one(not head gasket)on the top of which the valve cover is fitted over the cylinder head.A new packing will cost Rs 50/- at Honda.

3.Tighten the bolts removed.This will definitely stop the oil leak.Period.
