Threebond is a rubber based gasket paste. It will seal as much as a paper gasket if applied evenly.
Thanks for the info, any idea where we can get this Threebond paste in bangalore? Is it available in any auto accesories shop?

Try at any two wheeler spare dealer. It's not that hard to get. Yamaha showroom may also have it.

How does reducing the thickness or the paper gasket from the cylinder head increase the bhp by 1.5. I guess this power is measured at the crank?

By removing the cylinder base gasket ,and applying 3 bond in its place ,you reduce the piston head clearence by 0.5 mm(the thicknesss of the base gasket),increasing compression and increasing power/

All engines will benefit from higher compression. However just check if you have the right tolerance to play with. In all cases you can blindly go for a 0.5mm reduction on all bikes, from a CD100 till a Karizma.
Venu has made it clear above.

Base gasket, the one between between the block and the crankcase.

yesterday i asked my mechanic about this mod(remove gasket with threebond). And he told me two things.

1. By removing gasket i can increase the compression ration but it also looses the timing chain as well. And this could cause the fast wear and tear of chain and chain tensioner as well.
2. Threebond is not a 100% replacement of gasket.

So my only concern is point 1, As everybody know how much a karizma's chain tensioner cost

1) Cam chain tensioner would take up that slack. Use new Karizma's chain tensioner.
2) If not threebond, you can use anabond silicone rtv sealant. Definitely a complete replacement for gasket.

Looks like your mechanic is more knowledgable than a motoGP engineer.
The 2 solutions are,
1. Yes, u will increase the compression and FYI the cam chain tensioner can accomodate upto nearly 2mm of extra slack easily.

2. Threebond is not a sealant? Threebond is used in sealing crankcase bottoms/cylinder head covers(which ideally require more sealing compared to a cylinder base....which does hardly any sealing job) and have very high heat resistance.
I'm just giving a few short cut tips to get some kicks out of your karizma.
