so what parts did your famous mechanic change ? did he install some relays or has he increased the battery charging rate ?

Hi Chinmay,

Congrats for ur new machine. I did feel that only one headlight at a time was a lil disappointing but its only look wise. Been riding for more than a month now and never felt the need to have both lights ON. Ya people do tell me ke KAANI lagti hai bike and all but its ok, I am happy with it. I someone wants to see the bike with both lights on I just press the pass switch for a few secs.
I dont mean to disappoint you but there would be quiet a few potential FAZER buyers reading this thread and the message is :
Functionality wise one headlight at a time is good enough.

fz looks good

Headlight issue electrical trms demistified

Buddy... did't we ever studied about Serial and Parallel connections in our physics.. ???
Thats The change that has been changed with my bike electricals..!!
The exact PArts newly used are:-
1. A spocket.(Square cubicle box type)
2. 2 double wiring supporting bulb holders..
2. Some new wires.

Guys.. this solution increased the power of my headlights by almost 30 % .(Now its super bright with no changes in the original bulb)
My advice is.. Because the bike is new.. wait for some time till car/bike electrical mechanics get used to this bike's system and then go for the kill.!!
In my case the mechanic was an intelligent one with his theory and practicals at top notch.
He had already worked on 10-12 fazers prior to mine.. (he had studied the complete system off circuit design).

Yup .. he used 2 spockets and 2 new relays. !!
Plus as i figure out he changed the wiring from serial to parallel.. so that battery may sipport the increased load.. as we study in physics..

Thanks buddy for your well wishes..
but using 1 headlight as given or changing two both is a personal perspective.
i like mine with both on..
And if some cutting or damage or say chedchaad was being done with my bike for the change.. i would have never gone for it..
But because i found the solution good enough.. so i did it.. By the way i myself is an engineer.

Jaipur AKAR YAMAHA not providing leg guards.

well buddy yehi to problem hai.. my yamaha dealer is not providing me with the leg guard.. and the more so idot mechanic there is saying ki leg guard on the fazer is not even possible because of its fairing(i know he is wrong because i hav seen pics of fazer with leg guards). So ab lets hope ki some local shops be he solution to my problem..

Whatever you have done, the fact is that your bike now runs a 70W load instead of the 35W load. How long since the mod is done? And do you drive in traffic, where rpm < 3k rpm most of the time? If yes, I doubt this thing will work without the battery discharging.

And if it does work, it means Yamaha has put some generous safety margins in the alternator's designed power output!

Let us know after a week!

yes althaugh its has just been .. 4 days till now.. but lets see... i hav full confidence on this measure.. all else the time will tell. if it still works for me even after 30 days from now on. I think then we hav a jackpot solution.

please enlighten me whats a spocket ?

I guess it would be a socket/connector!

Lets study some physics now.

Assuming bike battery voltage = 12V

Each Bulb wattage = 35W
Calculating Resistance(R) of 1 Bulb:
Power(P) = Current(I) x Voltage(V);
35W = I x 12 V
I = 35/12 A = 2.9 A
R = V/I = 12/2.9 = 4.14 Ohm

Case 1: Both Bulbs in serial connection:
R = R1 + R2 = 4.14 + 4.14 = 8.28 Ohm
I = V/R = 12/8.28 = 1.45 A
Power required by battery:
P = V x I = 12V x 1.45 A = 17.5W

Power Supplied to each 35W bulb = 17.5 / 2 = 8.75
Inference: Both bulbs run at 1/4 Illumination, i.e. Reduced illumination as compared to stock, decrease in battery discharging rate 17.5W as compared to 35W

Case 2: Both Bulbs connected in Parallel:
1/R = 1/R1 + 1/R2
(Cutting the Carp)
R = 2.07 Ohm
I = V/R = 12/2.07 = 5.8 A
Power required by battery:
P = V x I = 12V x 5.8A = 70W
Power Supplied to each 35W bulb = 70 / 2 = 35W
Inference: Both bulbs run at full illumination with improved visibility but with increased battery discharge rate 70W instead of 35W.

Conclusion: If Yamaha hasn't considered that users will be doing such mods, you are running towards deep shit (Dead battery + no kick starter + Middle of the night)

Exactly! Let's how much safety margins Yamaha keeps! Nice calc there. Was too lazy to come up with them!

Hey dude give me some idea to do sticker work on my Black Fazer!

guys any suggestion where i can place "46" on my Yellow Streak FZ?

im thinking in the rear under the Yamaha logo?!
