Is anyone using tubeless tyres in unicorn
If yes which one?
How is Michelin tyre with tube?

Here the dealer told me that tubeless tyres 100/90 18 is made only by birla

Hi friends,

I have a 1st gen H........

Thanks..
Prashant.

Hi Prashant i have been feeling stiffer suspension since i bought the bike in 2013 so i think Mono Suspension does not really work specially with solo rides !
Bumps and pot holes effect is directly felt on back ! However when there is pillion behind suspension does really work well !
I am also looking for solution

The best solution is to give it some time..You will get used to it.. It's been 8 years through all ups and downs ..My back doesn't care about it any more..

I fully agree with our gixxer bro. Piston should have 0.20 mm gap between bore and piston without rings. For easier way to find out a piece of paper from a standard notebook can be inserted and nothing more. This is problem with new HONDA UNICORN and shine.

I have heard 2 shines straight out of showroom having crank sound. Also most shines are smoking in 30-40 k. This was not the case with the old shines. But from 2010 onwards i am seeing this problem. My friends Uni started smoking at 50k. The bore kit was replaced in showroom and after 1k bike started consuming oil. Then he came near me, when i opened the bore the piston has as much free play as your photos and piston was covered with oil as your photos. I then went to my mechanic and he said that all new bores come like this. Only solution was to Bore out or install new bore kit of achiever, we got a first oversize USHA piston and went for boring on boring and honing machine. The bore after boring was so tight with new piston that we have to push it to move, that too without rings. We have it installed and till now he has run another 50k and still no problem.

What Honda is doing is that it is keeping more clearance between piston and bore and rings is what seals the bore. The result is that bike feels free out of showroom, no special need of running-in, and also mileage is more. AS friction is less mileage is more. But the problem is after 10k the top end will decrease, engine will consume oil in small quantities, and what not, also piston slap will occur.

Now do not think me wrong but previous model unicorn(spoke wheels), shine doesn't suffer from this problem, even i feel the new activa will face this problem. Ride a new bike from showroom both Unicorn and extreme, you will see the unicorn will feel smoother and more free to rev than extreme, but after 10k extreme will rev freely and quite fast. Even my extreme took 10k for it to completely open up and mileage also increased slightly after that.

The video that you have posted it looks like a standard piston is sliding in an oversized bore. Your old piston which has run only 1k shows severe oil burning which clearly indicated that oil was seeping into the combustion chamber. This is the case with all shine,unicorns. Also you will hear the crank sound at only 40-50k. Believe me as i have opened a lot engines alone and also with my mechanic.

Even our stunner is feeling like that it is having much less compression than my extreme, i am not comparing it with my Joy as it will feel like no compression with my JOY. May be after another 5-6k i will see that what is the positon of the compression. Its because the stunner is feeling lazy to rev, although mileage is good at 62-65 kpl. Earlier the bike was feeling free to rev.

So the solution is to bore using boring and honing machine, and use 1st oversize USHA piston, get an acheiver bore kit or sell the bike and get another bike from other companies.

after 2 months i gave bike to my cousin he called me and said bike is stopped on road and not starting.
i told check some things, after that he approached road side mechanic, they checked oil level in bike, it was not there/very low.
mechanic opened the cylinder head cover gasket, it was damaged/torn completely at one point.
that's the reason for oil level low. i was surprised for misthinking that it will not cause complete oil leak.
..
i don't want to do major overhaul - cylinder bore/piston rings/valves.
what shall be done minimum to keep it running in decent condition as we don't want to run in this less mileage condition.
