Liked that bit of honesty in the post where u said low end has detiriorated.

Appreciated.

4800 rs -- what i would do ???

3000km ride , i dont care if i had a stock ehaust or no exhaust :-)
Thats my take .
Santa

Thanks mate!
3rd service is due in next 200 Kms.. Had already planned to get the chain cleaned properly.. Hope the issue gets resolved with it..

good suggestion.but i dont think anybody in trivandrum yamaha service center will have the equipment or the knowledge to do an a/f alteration.even i do not have proper knowledge on the same.i read in different threads about ecu remap,k&n filter and stuff. ecu remap is a risky affair.if done incorrectly all hell will break loose. besides how many even know the technical stuff associated with ecu s.ecu remap,FI,airfilter and such stuff are fairly new to the indian biking scene.even the head mechanic at the yamaha service centre admitted this honestly.they belong to the old school.we need some young talented guys like joel to set a new trend.coming to air filter how many r15 owners know that the machine has no o2 sensor to exploit an air filter. k&n is a big hit among r15 and pulsar owners in tvm. no one knows their stuff out here including me. what i am telling is that right now i have no plans for any other alteration on my bike. i did the exhaust because a FFE and a sparkplug are the easiest and simplest way to enhance performance.right now i do not have the time or the money to experiment like joel.the r15 is an awesome machine the way it is made. many designers might have spend so much of their energies in designing such a machine.i like my machine the way it is.all these are my personal opinions. i am sorry if i am boring all you guys.thats the way i always have been

The stock ecu is not remappable.
The FID tool is available at the SC. There is a manual with that.

Old school guys also can adjust the AFR :-P
Its really eazy.

Yes there is no o2 sensor on r15.
Santa

you gain something by loosing something

I dont know what makes people here feel that I get some free money or rather I have some super deep pockets. I need to admit here that I'm all on my own and all my engine and bike exploits have been off my salary account month on month and little by little. All these years I have saved nothing except for the knowledge I gained in the bargain. Not a penny otherwise.
Only my racing projects are funded by the team.
neither do I have any time in the world to sit idle and plot an engine hack lazily. I really wish I had all that money and time though

Dude, you have got a few things mixed up here.
Let me go point by point.
*There is no hell that can break look with an ECU. FYI, the R15 has an open loop module. The R15 is mechanically limited to a large extent!
* Changing the AFR is not easy again. Even with the FID you need to know what you doing. Then there are mechanical changes that need to go in as well.
* Most people here already knew there was no O2 sensor on the R15 as I have mentioned it a lot of times here and even if there was one, it cant vary over 5%. You need the tools to play to make it stoich!
* Any free flowing exhaust made by any Tom, Dick and Harry will make the engine rev quickly and will improve some range of the power. Well a tuned pipe will give what u want. Also I never quoted anything for my designs. I said generally people quote 10k, but your message conveys a direct blow on me. I got a few calls and messages on this, to clarify
* The R15 engine is still less potent than an RTR. So lets not talk about engineering on this machine.

How I know all this, coz my job involves working on the R15 engine for extracting every drop. I have done every possible permuation and combination on the R15 engine, that one can imagine. And I know how much more potent is my 2-valve RTR engine coz I push both to their limits.

Here we go.
I aint comparing anything here. Unto each his own. Please dont say somebody is inferior to me, be it even you. Nobody is God, its just that some excel at a different level. As humans, we are all almost same.
There is no frustration here man, its simple physics that people are not following. Yamaha has a good pipe, but its overpriced. Then we have some mumbai guys who build a straight pipe with a wrong design yet demanding 10k, then we have the likes of automech and KRP who have always learnt the art of making a straight pipe header pipe and shoving a canister and calling it a performance exhaust. I aint here for selling anything. I might not selll anything at all from my end. Its just that people are paying for something that any tom, dick or harry can actually fabricate inhouse. Trust me, its not any pain for you to fabricate a similar pipe as the Automech you have, in your hometown for less than half of what you paid them. When you paying that kinda money, you ought to get the right stuff. Any pipe with no baffles WILL make the engine free revving. You WILL feel more acceleration. But only a dyno will tell you the actual story. Which nobody follows anyways in India.
I dont have to talk about what difference my stuffs make, coz its got enough data to support. From v-box to dyno results. Right from the days of evolution, one man has tried to outpace the other, so the same goes to tuning. Same applies to me as well.
About your points.
* Any gasoline ECU will not break any hell loose on a given engine. Its always a marginal 5-8% normally, inless its mostly forced induction. Thats not hell in any means. Diesel boxes however make a more significant bump due to their nature of combustion.
* The FID is no miracle either. Its just a diagnostic tool. Cant do much to tune the R15.
* It just sounded a little different earlier, hence
* The R15 is indeed a good bike. No wonder we all own it.

Sorry for breaking the chain here.. Just need some help..
My bike needs some work done at the service station and I went there for the inquiry yesterday. I was thinking of putting Yamaha Fazer's horn to my R15. Will it have any adverse effects on the machine? I asked the service engineer there and he said they can be fitted(because that was the primary concern that can twin horns be fitted to R15 as it comes with just one horn as stock).

AFAIK there may be some battery issues due to double horns but other than that will there be any other effect on the bike?

Kindly help.

Thank you in advance!

LOL...i too had to post something but after reading the heated discussion here thought i should wait!!

so the guys who have removed the cat con say its not worth the effort...dropping my plans now!!

I found out a thing worth billions for "exhaust guys" and "CatCon guys" here..

There's a seperate universal thread on Exhaust..
Go there, burn the floor!!!!

I kno, I kno, that u already know bout exhaust thread, but if you know then hell use it man!!! And let the poor guy post his querys.
:-P
:-)

P.S. - Just kidding! Read light hearted.

Shanz

man oh man...u crack me up man..lol

You can fit the double horn,just make sure you add a relay so that it doesn't load the circuit.

And that you don't mount them on the radiator. No battery issues.

i apologise for boring everybody with some one-on-one with joel.please go ahead and post your queries

guys chuck the exhaust . Better if you guys meet up and discuss this issue

I have last 5 pairs left out of 15 HIDs . 3 Pairs of 4300k H4 HIDs are going to meghan in mangalore .

2 pairs left . All are H4 4300k single beam HID . Grab it asap.
