Tappet settings are not required for FI , the FI adjusts optimum fuel-air ratio without any settings required, however if u install a FFE or FFF then ECU remapping and/or tappet setting is necessary if your engine is running lean.

Tappet settings is very much required for the 220 Fi. The Fi only adjusts the AFR, not the Tappets.

Check fuel mix for top end speed, the bike can reach 145 max speed but its a false speedo reading, true max speed is not more than 125-130.

True top end for a Fi is about 135!

Tappet settings is something which is essential for a bike as it is with which the bike breathes in and out to be precise. Tappets themselves really last long, but need periodic adjustments which are essential because, too loose or tight tappet settings may adversely affect the engine's performance and life.

Tappet settings have unique setting regimen and it's best to let them in the PBK for a proper setting. I don't remember the mm gap that's required. But maybe Praful or others can add throw some light on that one.

AS the AFR is adjusted by the FI would tappet settings be as necessary as in a carb version ?
Where are the tappets exactly placed ?

The top end speeds I got from the PBK here in pune, they say the top end for FI is 130 and for carb is 145

Tappets are a mechanical part of an engine. They transmit the motion of the cam to the rocker arm which in turn actuates the valves. Here's is the simplest diagram I could find for your understanding -> Click!

The part #12 is the Tappet. Now due to wear and tear of the valves, the tappets need to be adjust once in a while as the clearance of the valves changes with wear.

Now is it clear?

As I mentioned earlier the irrespective of Fi/Carb they will need tappet adjustments once in a while.

Well I wonder what will PBK say when they see a 220Fi do 140+ and a Carb 150 on the roller bench that most PBK's had

What could be the reason why rocker arms are breaking now? 2 P220 carbs have had them replaced. One at 47k km and the other at 15.8k km.

The funny bit is, that these were replaced at a regular service, not after a breakdown. I mean, how can the bike still keep running AFTER the rocker arms have broken.

Anant, in my case it was the pins that broke off from the rocker arm, not the rocker arm in itself, refer to the figure in the reply you quoted, the part number 20 is the pins that broke off, it saw the pins when they drained the engine oil.

In my bike's case the bikes engine is producing soo much of noise when it is hot especially during the idling the sound is like sewing machines sound got irritated with that sound but in the higher gears and at higher rpms say above 4k the sound is negligable so took the bike to the svc the mechanic after listening to the noise finalised that the rocker arm should be replaced inorder to eradicate that sound.I didnt listened to his words and forced him to do the tappet adjustment to my surprsie the sound is same didnt find any difference so as the bike is in the still warranty asked them to change the both rocker arms now the sound has gone and the bike is smooth and very responsive than the earlier.

That gives me creeps! I've been pondering about the same. I know, one being 47k kms it's okay to get it changed, or is it?

At 17k is what I am getting concerned now. Or is it Bajaj for us? Damn!

But Krish, how did the bike run if the pin itself was broken bro? I am confused and getting paranoid?

What sort of performance issues did you feel before changing the rocker arm pair and what sort of sound and issues were you experiencing. Can you elaborate a bit?

The bike wont run after the rocker arm has broken, unless the arm just fractures but still stays in place still actuating the valves!

And guys chill dont start worrying about your rocker arms.... hello 87K run P220 here and just run its been ripped and ripped and ripped from the start. Everything is still intact!

Beats me mate, i asked them many times, what might have caused the pins to break, they dint have an answer apart from that newer vehicles are having them changed very often now.
Then i asked if the engine could get any kind of damages, for that they gave an instant answer NO.
I saw the pins myself when they drained the oil. Had to step behing the glass wall by the time they opened the head, the service manager was making a fuss about me standing there.
And he did mention there were 2 of them , so maybe one is enough to work, or maybe the rocker arm works fine without the pins apart from the noise thing. But then why is the pics there in the first place. Dunno man..even im confused.

but let me tell that i felt no difference in performance at all, before pins breaking, after breaking and after getting it replaced.

So i gather that the pins breaking off doesnt hamper its working in a major way to cause any damage.
Am i right ?

That makes it clear. But still a broken chip is always a thing of concern. Sigh!

That's the exact word I wanted to hear at least from someone. Sigh again!

Well, then that sums it up I guess, but still need to cautious I guess.

Sometimes I get so elementary that I want to get to know everything from the basic all over again. Manufacturing defect for me I guess

Yes! And I get it now, you can see that unless the rocker arm itself isn't in two pieces then you have an issue. If it's just fractured, not to the point of giving up, then I guess it will run. But still a fractured rocker arm is a major issue, I guess. I mean you just can't trust the bike for a long trip with a fractured rocker arm. That's disaster in middle of nowhere.
