If any Impulse / Hunk / CBZ Xtreme owner is in need of the cylinder & piston set, pm me. Done 70 kms on a new impulse and replacing with big bore kit.

Ohh, good, but replacing with what?

Also let us know the complete detailed process with pics...

Yes it was all hanging when i lifted the bike - SC mech said this will happen if i dont remove and clean the pads every 2k -they changed the pad and disk plate put new oil in it -for a long time after that incident i didnt touch my front brake at all - only used the rear brake - only recently i started using the front disk again .

My front forks when it goes through a pothole makes this sound - it sounds like a chirping bird .

Rings are available and it is game by ASC for selling of bore kit. Since you will do the work in vellore, do a small home work. Get there early. Go to place where there are a lot of lathe workshop. Ask them where is the shop that sells pistons and rings for bikes. Go to them and ask rings for extreme/hunk/unicorn as all are same. Get GOETZE,MAHLE or USHA rings and fit. OE rings are available and let me ask my retailer friend tonite and i will post.
Usually on the packet of rings the manufacturing date is printed.
There is nothing wrong for you to sell the bike. Just ring change will make the bike fly. If possible go for big bore kit from Joel as he provide stronger rings and they will last.

I ve already taken the pics, but they are in my PC. Will upload this weekend, when i go home.
Yess, man. DIY is a one way trap. Once in, you will only go deeper and deeper.

No what I meant was how did it happen?? You just pressed the front brake lever and the disc shattered into pieces? (i interpret that the disc was 'blown' off jusy like a bomb blast ) And how does 'removal'/cleaning of pad help? Cleaning it required for lesser abrasion/friction and improve braking performance. Pistons are kept lubricated by topping up/changing of DOT3/4 brake oil. But how can a mechanical piece like that just blow off???!!
Sry dude, if I kept repeating the same thing. All I'm interested is in - HOW!

Disk blew off ? How ? Was the brake pads low on friction material ? Was any work carried out on the disc earlier ?
Please let us know what exactly happened so that we can take necessary precautions to prevent that from happening.

sarbanoxley,
Check the caliper bolts (the fourth picture here) now, tighten it properly and forget it.

Actually it happened at the worst of times - was coming from funeral of my family doctor - no sleep and crying for 2 days - i thought my life couldnt get much worse than this and then on the highway while returning home i had to avoid this truck so jammed the front real hard - and heard this sound from the front and BAAM the lever offered no resistance at all - i only had a fraction of time to react before i was smashed like a pumpkin - jammed the rear as hard as i could but at that speed it was not working well - so closed my eyes and went off to the side of the road - mowing down this innocent guy in the process .

I was too concerned about the injured guy so didnt give much attention to the bike - only thing i knew at that time was the front disk failed - people helped me get the bike to SC - and the bill now that i remember was more than 1.5K - i think the disk alone cost me Rs 900 (sorry for the confusion) .

wow thats awesome guide - ididnt know it was that easy .

yeah thats a possibility as it was hanging - couldnt look closely at that time - will check if that bolt is tightened properly .

Sooraj dude...where r u? It is weekend and I hope you remember that the disk pad replacement/cleaning pics are due! :P

Hi Guys!!
need help regarding time periods/KM's after which certain parts needs to be CHECKED/CLEANED/REPLACED in our rides.It will be very helpful for all of us :
1)Front Disc Pad/Oil
2)Rear Disc/Drum Brakes
3)Carb Cleaning
4)Tappet/Timing Chain
5)Spark Plug
6)Air filter
7)Carbon on cylinder head

aside my accelerator is not revving freely(spring action is not there).where and how can i adjust it?? i have even tried removing side weight bar.

1) Front disk pad if not replaced in time can damage the plate so i change the pad every 8K just to be safe . I dont know how to take the pads and clean it myself so i just use water at high pressure to do the job . Rear i try to remove and clean it every 3K .

2) Front disk oil is DOT3 i replace it every year dont count the kms - this time i am going to try DOT4 but dont know where to find one - motul has dot 4 brake fluid.

3)Air filter i just take it out myself and hit it hard on the floor repeatedly thats it - i saw this is what they do in SC they just tap it on the floor couple of times and put it back in .

4)Tappets are tricky so dont touch it unless it needs the attention.

5)spark plug i never cleaned it but change it at 8-9K kms .

6) Cylinder carbon removal no idea mate .

also lube the chain every 500Kms with a good 90 grade oil.

going to buy this book and try to do little bit of servicing myself from now on - unlike you city boys i have to travel a lot to get anything done :

ABC of servicing And Maintaining Your Honda Unicorn 9381576731: Book: REGOS (9789381576731) | Flipkart.com

the book says procedure to adjust the clutch /front and rear wheel servcing etc for the uni. - bet its the same procedure for the Xtreme - if some day sinbun writes a book like this for the xtreme i will buy that too .

@sinbun today only i noticed white smoke when i revved the bike hard on neutral - will get the rings from unicorn and fix this once and for all this week .

Nice me too waiting
