Is anyone running their R15 with NGK Iridium Spark Plug without Spitfire Cable?

Any observation on what's the effect of NGK Iridium Spark Plug with and without Spitfire Cable.

Yes I am.. But mine is v2.. Better (crispier) acceleration and better fuel economy.. Nothing else..

I second that. But never happened on my v2. I thought nothing has been changed. I used the same bulb for about a month. And I used them double beam (both high and low). Never had any battery issues though. Strange. Then is anything so different other than the tail light?

I knew it was 15w+25w. Pilot lamps are 5 watts each.

Ya read it in the R125 community. So it was you who installed the R125 RR unit and rewinded the stator. Good. You on FB? :P

Pilots are 5W each, tail lamp is 5W and brake lamp is 21W on R15 V1

Yes, I am on FB. Check your PM.

^^^ it's not so simple as it being a 'broader / wider'. Putting a broader/ wider tyre does not automatically give you better grip or stability. Along with the increase in width, there also a considerable change in the 'profile' of the tyre. Depending upon which make of tyre it is, there will also be a increase in the 'height' of the tyre. There is also increase in weight of the tyre.

All the above have some type of implications. For example the increase in height will change the weight distribution of the bike while so changing the ride height. These In turn will change the handling dynamics of the bike considerably. The increase in tyre weight translates to increase in unsprung weight. This in turn affects the suspension dampening and rebound rates.

Ok I checked the link but there is no detail regarding the shipping to India. Neither can they calculate. How much did it cost you? How did you get it to India?

20 quid + shipping, but I had a stator coil along, so can't accurately calculate shipping.

But in the R125 community you said R15 comes with 19AWG and you rewinded with a 18AWG. Someone also told me R15 v1 comes with 20AWG. Confused. Please confirm. Here is the link to your post on the R125 community. R125 Stator Assembly On R15? | Yamaha R125 Worldwide Forum

The one mentioned in the R125 forum is correct, I checked the gauge with a micrometer. Age has taken it's toll on my memories :P

Any link? Please?

So when you say you upgraded the harness, what gauze wires did you use for that? Or is there any plug and play upgrade available for the harness?

I had some Teflon insulated wire (heat resistant) around house, it was about 75% thicker, I didn't measure the gauge. It was just a precautionary measure. The female connector got burnt, but I was able to find a better quality replacement for that at S.P Road. If you happen to be in Bangalore, visit S.P Road, you'll get all that you need.

PS: Build quality of the R125 stator vs R15 stator is visually evident.

Need help regarding upgrade of headlamp for stock R15 V2...

The stock headlamp holder for R15-V2 is HS1 PX43t.
I plan upgrading Left HeadLamp alone to 55/60W H4 (Since no 55/60W available for HS1).

I am sure I will not face battery drain, cos I rev her high ( always more than 7500 rpm) and till date I always used only long beam (means 35 + 35 =70W) and no issues with battery.

My worry is whether the reflector will be capable enough to hold the heat emitted by 60W in place of 35W?

Also Please help which of the below two flash light would fit R15-v2

Philips Lighting India - W1,2W - Philips

Philips Lighting India - W2,2W - Philips

came across something thought to share with you as i think we can understand lot about the R15 suspensiontoo

Stock reflectors can handle the heat. People say, you can't.. but you REALLY can. I would be more worried about the battery. 35+35 = 70W, but 60+60 = 120W. 14Ax12v = 168W of power output from the rectifier. 168 - 120 = 48W of juice left. Radiator fan, tail lamp? (1.5 x 2)A x 12 = 36W for horns?

Regarding HS1 and H4, the only difference is the that H4 has a roundish base, but HS1 has a third notches. In India, we call them H4. You go to a local automotive store and ask for HS1, he would probably have no clue of what you are talking about. Ask for 55/60w H4 (OSRAM NB, Philips Xtreme Vision all come with notches, but call themselves H4.. so some confusion there)

@awesomeneo - i did my experiment on my nano where i changed the internal cabin lights to white led 15 pin one 0.8 v and i checked and found that same led can be fitted in the R15 Tail light too, but the issue is what to do for brake light bulb.

In addition to the above mentioned, there is the fuel pump, fuel injection system and ECU to be considered.

My plan is to change just the headlight of left side with 60/55W.
So in short beam It would consume 55W ( definitely no issues, because i never used short beam in ma bike till date.Always ran with 70W)
In high beam It would consume 60+35=95W ( 25W in excess)
As a plan of compensation of excess 25 W I will change the pilot lamp to LED and remove numberplate tail lamp.
so 2pilotlamp(10W) +1numberplateLamp(5W)=15W will be replaced with 2LEDPilot Lamp alone(2+2=4W)
by this I will be saving 11W
So as a sum I will be using 14 W in excess than stock set up, which I believe will not bring me any issues.

Hey guys can someone who is running a HID setup post a photo as where the blast should be kept..

I bolted the left one onto the horn mount, the right one is tucked in at the top of the front fairing near the fuel tank.

Do you live in Bangalore? I have an old wrenched tail lamp assembly (long story short, got rear-end by a BMTC bus).. You can salvage the wiring harness and the bulb holder for your experiment.

Shortcut: Just get the LED tail lamp from the link I posted earlier.

Let's also add radiator fan to that list :P

14W shouldn't make much of a difference. Just don't use high beam within city limits (low RPM, plus the radiator fan kicks in often). On highways, you should have no issues with this setup (because the radiator fan is almost never running on the highways)

I tend to remove my ballast often.. so I have sandwiched the mount between one of the fairing clips and the bolt on the RHS fairing, but most of my friends have hidden the ballast under the speedo.. (or rather behind the speedo)

Hi Guys,

Requesting your help again....

I am facing starting trouble since last 2 weeks. The nature of starting trouble is confusing and I couldn't identify the specific reason yet. Sometimes the bike will start without any fuss and while riding there is no problem. Once its switched off after riding(irrespective of ride distance be it 1 meter or 1000 meters) it fails to start again immediately. And sometimes even that problem is not faced. I tried turning on bike and leaving it like that for few minutes and turned it off and then started again (it started without any problem) to ensure that it is not a fuel pump heating up problem(like a fellow member faced and had to change pump at cost of 7500). After trying different permutations and combinations i feel like the bike starter is not activated since the system is sensing that bike is not in neutral or that clutch is disengaged while in gear. I don't have much idea about how the system identifies if the bike is in gear. Can I have your thoughts please? If anyone faced similar issues please leave your suggestions.

What sounds do you hear whilst attempting to start? On mine all I hear is the relay clicking, initially when the problem first appeared, it would crank around 50% of the time, then I would hear the starter motor spin, I guess internally without turning the cog.

I currently have diagnosed a faulty starter motor on mine, unfortunately the part is unavailable with any stealerships here. My friendly local mechanic (he's actually very good) claims he can repair it as it's most likely the carbon brushes are worn out, hope he's right.
