Re: Yamaha YZF-R15 version 2.0

If you don't want to trouble your engine, its best to stick with stock, but if you really want to get a good exhaust system, Leo Vince is much better than the Daytona one.

Re: Yamaha YZF-R15 version 2.0

Thanks Ivin for your inputs.

Re: Yamaha YZF-R15 version 2.0

Thanks everyone for your inputs on it. If the exhaust system is changed to Leo Vince what would or how would it impact the Engine? Sorry for asking you guys more questions.. I am just trying to get uniqueness to my ride... And also trying to understand my R15

And guys here is the pic of the R15 which has got the daemon looks..

Re: Yamaha YZF-R15 version 2.0


Basically the fuel maps that are loaded in the ECU is for the stock specifications , stock exhaust, stock intake. Now when you get a FFE which is a slip on or a full system, one of the variable changes, that is the exhaust part. So the stock fuel maps are not sufficient any more. And there is a chance that the bike will be running lean because of this. So ideally you will be required to use a complimenting map along with the leo vince exhaust. And I don't think you can load a custom map onto the stock ECU of the R15, senior members can comment more about this

There is nothing like plug and play when it comes to hot rodding, so if you change one variable in the equation, it has effect on the whole picture.

Re: Yamaha YZF-R15 version 2.0

Thanks a lot Krishna... That was lot of info. I just checked with one of my friend and he gave the suggestion for better sound. As I was not convinced I came up with the questions. It was very informative before I could spoil the ride by an after market exhaust. Thanks again for that..!!


Thanks

And one more doubt I visited a k&N filter mall that was put up in whitefield Bangalore. And asked them about the air filters for R15 and I was offered with an air filter worth of 4500 Rs.. and the K&N guys promised me a better performance then the Stock one.

So what about your thoughts on it ..??

Re: Yamaha YZF-R15 version 2.0

Hi Royalz

As Krishna mentioned, Change in exhaust effects the exhaust, while change in Air filter effects the intake. Now K&N being high performance lets in more air which if not compensated by the ECU for air to fuel ratio, your engine will be running lean again. So i would say if you are interested in modding your bike, get an aftermarket ECU which compliments these changes. Without which you will be seeing more pain in the long term than gain.

Re: Yamaha YZF-R15 version 2.0

Like I said. It's all about the variables in a equation, you change one variable it changes the whole picture. If you have a free flow exhaust then you need a free flow intake too. Just a free flow filter would only give in more air into the system and with the exhaust part being the same , will give nothing more than a change in sound, which is pointless really.

Moreover these K &N filters do take in a lot of dust particles than a stock filter which is much more restrictive in the matter of filtering out dust. So more dust is never a good option, on a race track it doesn't matter, it's controlled environment, but in our daily commute in cities and all, that is not the right choice to make.

So please do stay away from such marketing gimmicks , there is no limit in what all they will say to convince you to buy their products, which is usually made for specific use only. U
nless you are really planning for a fully blown modded bike , then only consider a full system exhaust, custom fuel maps, bigger bore, free flow air filter and all. That is a totally different world outside the stock reliability.

EDIT : Also i missed out on a very important part, when using the K&N , the bike runs lean , again. Just like when you get only a ffe installed. Which is not good.

Re: Yamaha YZF-R15 version 2.0


Thats was a good write up Krishna. Thanks for the insight about the mods and the bikes performance. That was really helpful.

Thanks Jeevan. I will refrain from having the exhaust and the air filter changed

Re: Yamaha YZF-R15 version 2.0

You can go for free flow exhaust... But you got to change the ecu to powertronics ecu with custom maps suited for your bike,weather conditions... Etc.The full exhaust system and ecu may set you back minimum of 50-70k.. If you are ready to spend that much for a minor bump in power and sound, go ahead. Without changing the ecu, free flow exhaust is a big NO.. And don't fall into the trap of K&N. It allows all dust particles to enter which is harmful in long run even if you have the ecu to remap the values according to free intake.

Re: Yamaha YZF-R15 version 2.0

Thanks Siddharth. I think spending 50-70K wouldnt be a good idea

How about the projector lights? Like the one which is below.. Can I go with it? If yes, Can you guide me to the right place? I got those information from the below site.. http://www.bikervietnam.com/bfrm/sho...m-lt-SGshop-gt This is done in Vietnam and I am pretty sure even we have skilled ppl in banglore as well to have this done. Can someone just guide me to the right place ..??

Re: Yamaha YZF-R15 version 2.0

I had once used the knn stock replacement one once with the air cover on there was not much change in sound whatsoever but the engine would run extremely hot with the rad fan running for longer durations.... the spark plug too showed a chalkish white color suggesting lean mixture
But then I went to the svc and changed the co setting by + one and it became better and again changed it to + two it was ok the pick up Increased a bit but was not worth the cost and the fuel economy dropped by 5-8 .then some one suggested removing the cover of airbox for better air flow I was apprehensive of it and changed back to stock and donated the filter to my cousin who instead sold it to his friend
My 2 cents if u think filter job is plain plug n play then junk that thought of changing the filter and stick to stock and if u r willing to properly get into the matter and get ur hands dirty ( but with a risk of spoiling the engine if not done properly)then do it properly in a logical way


P.S. this is my experience iam not suggesting to go for it or telling to refrain from it choice is upto you

Hello Guys Im New To This xbhp Find it Awesome... I have A Question.. I have r15 v1 and tank is rusted it is clogging fuel pump can rusted fuel tank of r15 v1 repaired(Epoxy) or must be replaced?

Re: Yamaha YZF-R15 version 2.0

holy F...





inline 2-cylinder YZF-R25 that looks as if a beautiful YZR-M1 replica.

well then it's either this or the KTM RC 390 as my next sportbike a few years down the line...

assuming it reviews great like the R15 v2, i think i am sold just on the grounds of being a MotoGP buff if nothing else.

Re: Yamaha YZF-R15 version 2.0



OMG......!!! Thats really a power punch.. Sure will have goosebumps when you see that video... Holy S*$&..... Crazy

Thanks aditya for that video ..!!!!!!
