@samarth You are a P180 owner and R15 has better low end than that. This is the reason you dont agree that R15 is bad on low end. R15 has got nothing on the low end if compared to RTR. I didnt get a chance to Ride RTR Fi but I think it would be much better.

Tell me how to make the LED lamps.. I am game to try. hmmm, when can we meet for that?

Horn tuning, pull out the star screw driver from the tool kit, reach for the horn (I believe I did it from the top, if difficult, just open the black panel on the top LHS). There will be a screw on the horn (not the center one). Turn in quarter turn or less at a time either side and test the horn at each step... u'll get to tune it to the sound you want.

BTW, the tuning has a very short range... if u turn 1.5 to 2 turns, the horn won't sound at all.. gotta turn it back. Also, remember which side u r turning and how much so that you can set it back to the initial setting if nothing else is better.

Also, this is the same process for every electro-magnetic horn.

Thanks for the Guide. Can we a get a Manly voice from R15's horn by doing this?

nope... can either become a little sharper or coarse...

Thanks for that helpful guide, will try it out in the morning, too tempted to do so now itself though!

And regarding the LEDs, there's a shop here at chandanagar that sells LEDs for use as aux lamps. They cost 20 bucks each, but are multi-colored(keep changing colors, blinking and fading and crap). So, kinda looks cheap, and I hate them for that reason. But the good thing is, you can take the LED holder from that setup,along with the built in resistor and dispose off the stupid LED. And then, we can buy white LEDs from anywhere for around 7Rs each, and fix them in the already available holder :P

PM me about your home timings, and we can meet for sure

thank you ! hmm i thought the injectors might get clogged over time (just a thought) and would need maintainance.

hmm the rusting seems to be common , i guess ill give her a paintjob rightaway when i have it instead of waiting for the rust to come . prevention is better than cure


as far as making LED lamps , be sure that the LED's get a lesser voltage than recommended, (use a resistor for the voltage drop) , use a capacitor + I.c 's (small tiny ones) for making the power delivery smoother , otherwise even a small duration of overvoltage will fry the LED's (the bandgap is no longer there for photon emission, the LED just heats up then without a glow)

the circuitry isnt complex and the resistor has to be before the postive lead of the LED for it to safeguard the LED from overvoltage. its because unbranded cheap LED's really cant take much abuse unless you're lucky

ahaaaan the autowallahs put n such LED's to make their rides jhinchak

also ive seen these on some bikes

I'm available... tell me when it's possible for u!
I already have a pair of those disco LED's

Well, injectors DO get clogged over time(not entirely, but grime and slime you know), thus resulting in poor acceleration.But they can always be cleaned, it'll take years for such a situation to arise anyways..so no worries . And you can always use fuel like XtraPremium once in a while to "clean" the fuel system.

And regarding the circuit you suggested for LED, space is a very strict constraint here..so staying away from ICs is better. LEDs anyways dont need such a smooth regulation. They are just diodes, so they can take in large amounts of voltages easily, and conduct them with as low voltage drop as possible. An LED only fries away when the current figure goes crazy beyond 20mA. So, we instead use a simple current limiting resistor of about 190/200 Ohms to take care of limiting the current. And anyways, if we STILL fry an LED out of pure bad luck, we can always replace it with a new one for just 7 Rs.

Yeah, those "jhinchak" ride LEDs only!

LMAO! Didn't know you love disco LEDs too apart from pink!! Just kiddin, don take it seriously now .
So, as you already have the disco LEDs(let's call them so from now, would make it easier for all of us) we can throw away those discos and retain their holders+resistors, and buy a pair of new White LEDs for about 20 Rs together at the max..and i'll do the fabrication part for you. And you'll have cool looking LED Aux lamps that Yamaha thinks can sell for 500 bucks!

See how people try to make fools out of us, just a little bit of electronic knowledge is all that it needs! an MRP of 500 Rupees for something that can actually be made for under 20 bucks!


And well I have college from 9AM to 4:30PM, evenings are always better for me. Do buy those white LEDs from Gujrati Galli if you think it is possible for you (They're called 5mm white LEDs)

at least not expected here at xbhp.

A personal attack shows your feeling of 'inner revenge' . It doesn't look nice by making such kiddish comments on such reputed firms. You are directly throwing on Rahul Bajaj. Secondly why comapre bikes when thread name is 'yamaha R15'. User is expected to post his problems, experiances related with R15. For comparisons, make separate threads.
Why bajaj should drown in bucket full of water? have u any words for answer? Do you know its meaning?
I have gone through threads and have found that Thread starts with a motive and in between motive is lost. Then starts comaprisons of bikes and personal attacks. In seconds you finishes R&D of these bike manufaturers and think that you are super genius. Then take data frm different bike megazines, check their comparisons, post it here . This is R& D!!! What the hell is going on here??

and you are adding to it .. there's no reason to post crap on this thread and everybody is entitled to their opinion. (your post was crap in my opinion).

If you are offended kindly PM the person concerned. if you have something to add about yamaha R 1 5, do so on this thread.

I was going to post my experiance of yamaha R15 and i thought of reading others members views abt ownership. If i am not wrong Its ownership thread and why moderators don't delete the posts which are not related with 'experiance of owing?' it just de grade the title of thread..

post your experience .. mods will do their jobs in due course (hopefully ). Just try to ignore OTs as your reply will be another OT. As has been the last few posts which will most likely be deleted ( Aryan and MG have been deleting posts for the better part of their lives now ).

I replied to your post as you are new here. Ignoring henceforth.

Sir, it is but natural to compare two machines, be it on a thread here in xBhp or in real life. And I don't really mind throwing anything on any personnel of Bajaj; what the end user (read customer) wants is a performance machine, not something which even being a so called 200cc cannot even keep up with a 160cc mill. Now THAT's a real shame, if you seriously think about it!

And I am NOT a super-genius, I have never ever said I am, neither can I be one. I JUST asked Joel to clarify certain facts that I somehow already knew, which somehow seems to have not gone down too well with you. Anyhow, let us not take the OT realm further, if you want to discuss it, let's use the PM/ User messages; it's better that way.

I agree with most of your points but I still feel that even after you change the tyres of the RTR and hand it over to a professional racer to compete against an equally able rider on a R15, the R15 will come out on top on most stints around the track, if not every single time. I base my opinion on the feedback i got from Killer who until recently was the proud owner of both the RTR as well as the R15. As he has quite a few race wins and championships under his belt, I do tend to take his feedback seriously. In his opinion, no other Indian bike can really challenge the R15's supremacy on the track for no other bike inspires the same level of confidence on the curves.

Secondly, I myself have put both the bikes through the grind on my religious weekend trips to Lavasa valley (My bro owns an RTR). And although RTR is indeed a brilliant piece of machinery and by far R15's closest rivals when it comes to handling, the R15's super gluey tyres, sturdy chassis and aerodynamics makes it just so easy to charge at every corner, put your knee down and exit at speed you never thought were possible..and not just once but consistently.

I agree our tests were carried out on the RTR and not its FI variant, but as far as handling is concerned I don't think there is much of a difference between the two.

However, as I base my opinion based on results rather than assumptions, I decided to ask you for the track results for the RTR Fi and the R15.
