Re: Honda Unicorn

Hi,

Yes it is the same noise/engine strain and i am sure it takes out all the riding pleasure from you as well. Just few points to clarify

Are you also facing this issue only after putting AX7 oil from Shell
Did you do any tappet adjustment and was that useful
How could the engine oil change have an effect on the tappet adjustment

When i went to the service centre, they have replaced the kit valve set, gasket cylinder head, gasket head cover, ringset piston and the guide in valve and including labour it costed 2200 rupees . After this the issue got solved by about 50 percent, but still some engine strain/roughness is there.

Please let me know, if you have or you could solve this issue.

Thanks

Re: Honda Unicorn

Similar video has been uploaded by me just few posts back and a fellow member suggested a taappet check but i m still not finding somone who understand meanwhile buddy please just check my video if the NOISE is similar to urs ? as i am also running on ax7 the oil feels good n works well keep the engine cool

probably its just tappet

Re: Honda Unicorn

Hi,

Sorry for not posting updates on my issues with my bike. So the suspension problem got sorted out by putting extra padding. On the engine noise, as I said earlier, things were very smooth before i filled Shell AX7 from the Shell petrol pump, but after that, the engine noise became high- for a slight rise in throttle it would give big noise/strain in the engine. i have uploaded the video with the engine noise also(https://www.youtube.com/watch?v=zne8pzSCz9Q).

I showed it to the Honda showroom, they said the work to be done in the cylinder head, ie some valve would be bent and it should be straigthened by lathing. After doing this, engine noise has got lesser but somehow still the bike is not as smooth as it used to be before putting the shell oil. But the ride is not very irritating, somehow manageable but it is rough. the linear exhaust note, which i used to get is not present due to some strain in the engine.

Not sure what to do- but i have started to live with it. One alternative which i have is to buy a new bike. But then i test rode bikes like FZ, Suzuki GS 150 R, Gixxer, Discover 150, but none satisfied me like even my present unicorn. I have simply got addicted to the smoothness of Unicorn and cant bear the roughness in other bikes. I can only think of buying another unicorn may be Unicorn 160 but not immediately, as i will use this for another couple of months and see. Thanks again for all your help

Re: Honda Unicorn

Hi, Thanks for your reply. Yes there was some discomfort due to the helmet also, which i was using for the last three years. It was a bigger one and used to jump and fall on my neck bone. I got it changed with a new studds 3g ninja helmet and the pain slightly subsidised but not completely. But according to the advise in the thread, i got the padding up done in my front seat to provide the extra cushion, which solved my issue to about 90 percent. Some niggles are still there which are fine to live with. Thanks again.
