Hello everyone.
I've been riding my second hand Inty for about 1500KMs now. The bike is amazing. I've done a few mods like -

Powerage slipon exhaust
Signature Bench seat
Kemimoto bar end mirrors
Adjustable clutch and brake levers

Now I was looking into getting a new air filter - was looking at BMC or NGage filter.
But my doubt is that, I've read this makes the engine run leaner.
So will I need an engine remap of a booster plug like FuelX etc?

Should I prefer a remap or a FuelX?
And in case of remapping, would you know a good place to get it done in Bangalore?

Also has anyone tried the Way2Speed front suspension kit? I feel YSS and Ohlins are too expensive and maybe Way2speed can do the job just as well but have not seen any reviews.

Custom Db killers

My bike hit the 37 k mark a couple of days back. While heading back home, I heard a funny sound over and above my ear plugs and helmet. This "tinny" sound was "on" above 60 kmph and disappeared below the above mentioned speed.

I reached home and checked the exhaust and found the left db killer was loose. On taking it out, I discovered that I would not be able to put it back as the metal had disintegrated.

My exhaust is Powerage and they operate out of Coimbatore. I remembered seeing a custom made db killer in his brochure a few months ago and messaged the owner regarding availability. These db killers are longer and closed at one end.

They cost Rs.2000 a pair and I got them today. I put them into the exhaust with the given allen key and did a small test ride. The sound is a lot muted and much more easier on the ear and should be more "public friendly".

The odometer reads 37 k

Cheers

Not a mechanic.

Air Filter + slipons without a tune will result in a decrease in low end torque.

Booster plug, FuelX and remap are three different things, each addressing a different problem.

Booster plug fools the air temperature sensor into thinking the air at the intake is colder than it is, causing it to dump more fuel to maintain AFR. From my understanding this works in both open(wide open throttle) and closed (partial throttle) loop conditions.

FuelX does something similar with the O2 lambda sensors on the exhaust to influence AFR. However, O2 sensors are ignored by the ECU in open loop, hence FuelX only works in closed loop.

Remapping obviously gives a much wider control over AFRs in the entire rev range for every throttle input. And it is not limited to AFR and can also tweak timing etc. You can get the ECU mapped directly or install a piggyback like Powertronic.

Racedynamics in Koramangala make the Powertronic and Fuelx, and can also remap the ECU directly.

For what it's worth, FuelX, especially the Lite version (since that is what I have), does not justify its relatively low cost. The only gains you will see are on the butt dyno (if at all) though it may improve engine smoothness, especially if you have a jerkiness at low RPM. However, adding a tooth to the front sprocket is a much more noticeable increase if smoothness is all you are after. Booster Plug cannot be used on Euro5/BS VI bikes, says so on their own website. Remap the factory ECU if your bike is out of warranty, and go Powertronic if it is not (I did).

Thanks for this reply. It makes all the sense that I was looking for. I have been considering the Fuelx pro for a while but wasn't sure. I don't want to go into mapping or powertronic (at least as of now) as I don't feel I'm that big of an enthusiast/rider to invest that amount of money.
I was infact on my journey to make a DIY booster plug of my own. But you're right it won't work on the adaptive ECU of BS6 models. Thanks again.

Incase you have any insights on the front fork suspension upgrades also please do let me know.

That depends on what you want from the suspension.

The factory forks are an archaic damping rod setup that is very soft due to the fork oil weight being low and the springs not being stiff enough either. The Ohlins FSK100 fork kit is the same damping rod setup with preload adjustable fork caps and stiffer linear springs. The Way2Speed kit is also the a damping rod setup, but without preload adjusters and with progressive springs and a 12.5W fork oil. The Ohlins is in no way 3x better than Way2Speed despite costing that much.

The YSS kit is a cartridge emulator kit which simulates modern suspension through valves in the emulator. You can adjust preload, compression damping via the emulators themselves and adjust rebound indirectly through fork oil viscosity and level.

There is also the Andreani kit that replaces the entire fork internals with a modern cartridge setup.

In my opinion, if you know what you are doing and have the patience to experiment, the YSS kit is the most bang for the buck. On the other hand, if you want a plug and play solution that offers significant improvement, the Way2Speed kit is very good for half the price of the YSS.

Do you feel any change in torque in low revs and smoothness? Since you have header pipes that are not stock, I wanted to know how different they are compared to stock headers. I prefer the closed baffles on my bike too and have hardly run the bike with other ones which the mufflers came with. It has good torque and much smoother and mainly a pleasant exhaust note.

On the old baffles, is the blackening due to carbon deposits or the plating has just burnt off.

The sound is very pleasant compared to the sound with the original Powerage baffle. There seems to be better torque at low revs , smoothness is definitely there. The plating has come off to a large degree on the old baffle plus there is a mild trace of carbon. I did a ride today morning where I did 6000 rpm in 6 th gear and the bike feels very pleasant.

I am Curious and have a few questions,

1. Are these Aftermarket exhausts even legal in India ?
2. I assume, without any tuning there is no specific benefit of a custom exhaust?
3. Do these custom exhausts adhere to pollution norms ? or is there any way to verify a manufacturers claim?

PS: Post is made out of curiosity and not intended for any conflict.

1) No,they are not legal.

2) No, there is no benefit other than the sound.

3) I have done PUC check after Full System Installation and it was all clear.

1. Short answer - no they are not legal. Legality depends on the noise and pollution norms. If your aftermarket exhausts are in limits of both, you won't be in any trouble with the authorities.

2. There is little performance benefit from a slipon exhaust change only. A full system exhaust change will make more of a difference, also goes more towards the illegal side.
- There is weight reduction
- Better airflow - potential performance gains
- Improved throttle response
- Louder (maybe better) sound

But your ECU is mapped to the same old stock exhausts and to follow BS6 norms. So that's limiting the full potential of the aftermarket stuff.
Tuning will get
- better AFR making the bike cooler and safer.
- Performance gains of about 5BHP
- smoother throttle
- Safer for the valves, piston etc of the engine

3. Full system exhausts will not pass pollution tests. I don't think Manufacturers even claim that their exhausts will follow the norms.

1. No.
2. Yes. In fact, increased airflow without adjusting fueling, even if it gives a minor performance bump at the top end, will usually reduce low end torque.
3. Depends on the bike. If the cats are in the midpipe, then yes. In the case of the Interceptor, probably not, since the cats are in the endcans. However, you won't fail a PUC if that is what you are concerned about.

My full system exhaust DID pass the emission test. Do scroll above if you want to see the emission certificate.

Friends i need to brainstorm with you guys and find a solution.


I have had my 2022 Interceptor Mk II for 2.5 years now and have just clocked 20k on the odo. Earlier, in April, i got a serioes of long planned upgrades on the machine:

• Full system Powerrage exhaust
• BMC High performance filter
• NGK iridium spark plugs and cables.

the idea was to make the motorcycle breathe better, and hence return better power figures. I havent had it on the dyno, but the bike feels lighter, more nimble, but while the top speed remains the same (speedo indicated 170-ish), the way it gets there now is a lot more dramatic.



I rode around in the city for about 200 odd kms, before i embarked on a 3500 kms round trip. On the first day of the trip i clocked 1973 kms between delhi and Arrah in Bikar. Much of this was on three expressways - Yamuna, Agra - Lucknow, and Purvanchal. As expected, the milage returned was 19 kmpl.







The next day, i had to ride 511 kms mostly on state highways and then on NH 27, and guess what, the milage shot up to 29.



During my stay in my hometown i made trips to The hills (Kalimpong and south Sikkim) and tanother 300 kms day in the plains of North Bengal. The hill ride have me a milage of 26, and the one on the plains, 32! yes, i did the maths thrice over.



But here's the problem:

Before the return trip, i took the bike to the local RE service station in Siliguri, and they had to top up about 500 ML of engine oil. I had gotten servicing done in december 2024, and dince then the bike would have done less than 3k kms.

On the return ride (Route: Siliguri - Araria - Muzaffarpur - Gorakhpur - Lucknow - Delhi), i got a milage of around 30 for the first two days, which were the highways, and around 20 on the third day, which was just two e-ways), but i kept noticing some WHITE SMOKE from the left side muffler. Is that normal?

Additionally, i got the engine oil checked and they had to add another 500 ML. Thats 500 ml engine oil consumed in 1600 kms. now way is that normal.

My guy tells me to go back to the stock setup and send the bike to the service centre as it is still under warranty.

Before i do that i wanted to hear what you folds think? Could the mods have contributed to some sort of an issue with the engine?

Please help!

You did close to 2000 kms in a day on that seat?

If the engine oil is reducing, it is quite possible that the engine is burning oil since you mentioned one exhaust has white smoke from it. There were some posts earlier of oil reducing otherwise too. If it is still pushing out visible smoke on idle and normal riding, it is better to get it checked.

oh... i actually like the seat. i got it with the bike itself, the deluxe touring seat. also 1000 kms in a day haha. but again no issues with it
