Why the new bikes are not having fuel filter ?

Even in the bikes that were released 10 years ago or more, I've seen fuel filter just after the fuel petcock. But in the new-age bikes there are no fuel filter !

What's the reason behind that ?

Is that because all the petrol in India suddenly became crystal clean ?

Or is it simply to cut costs ?

I'm telling about the carb bikes. The FI bikes are a minuscule of the bike population.

Well I have been sitting with my manual and all the stuffs, I really dont seem to find any info about my bike's fuel filter maybe this leaves me to assume that mine doesn't really use one !!

I doubt that. Usually its integral in the feed unit which attaches to the tank. Not the traditional filter midway on the fuel feed pipe.

The new fuel taps have an integrated fuel filter which can be cleaned by unscrewing a single big bolt at the bottom of the fuel tap. And they have strainers inside the fuel tank too. Even the old taps had strainers inside the tank, new ones must be better.

Why is it so ? Does it serve any special purpose ? Or is it simply to save space ?

The old type of filters depend on gravity to do the job.
The dirt particles would settle down to the bottom of the Purcolator (?) and the fuel would flow out of a pipe that is a little higher up in the bottle.

The new ones would have a mesh surrounding the inlet pipe inside the tank.

I once removed this pipe in my Splendour. I don't remember how it was. :(
try the same on your bike and check it out.

The FI bikes typically have an integrated fuel filter and pressure regulator built into one unit.

Now, what about an oil filter? Where would I be able to find the oil filter on my Karizma?

It doesn't have one!

Karizma has only a oil strainer screen inside the drain bolt!

That's interesting. Any particular reason why? Are most Indian bikes built this way or is the Karizma an oddity?

I am not complaining trust me, makes oil changes that much easier! Twist, drain, refill. That's brilliant! On my other bike, I have to drain, take off half the plastic to get to the oil filter, drain more and then put it all back together. Don't enjoy it.

My old CBZ is having total 3 fuel filter one in gas tank fixed on top of fuel tap, one is to deposit the durt particles at bottom of fuel tap and last one is in fuel line which filters those particles which passes through aboved two filters.
Same setup i am running on my RD's.

I don't know the reason for that. Maybe Honda has a great faith in it's engine not shedding large enough metal particles Even the CRF230s don't have oil filter.. same engine.

Many other bikes do have oil filters, Suzuki Fiero, Apache, Caliber, Pulsar etc..

Can you name your bike I just dont understand this process and by the way where is your oil filter located !!

In my bike FZ16 the engine oil filter element is located in right side of the engine. Typically the small circular arch with three bolts near the engine oil filling let !! so there was typically no oil that could flow its way from there.
