I am with you there Sandeep. I have used public access and commercial GPS systems in the UK and have read some articles about GPS and the Europe's answer to it. I don't consider the open domain GPS to be accurate. Even with open skies the tracking is at mercy of #$%^& and the accuracy levels u get is about 7 meters. So, the GPS can be accurate but need not be.

It was just a test for the heck of it

It actually depends on the consistency of the satellite lock your GPS device will get. As far as I know, GPS tracking devices in mobiles are accurate upto ten meters most of the times.

All you need to do is get a lock (which even with A-GPS takes considerable time) and ride around for ten minutes on your bike - make note of the maximum speeds you hit at certain points.

Now load the track on your PC and you will see that even those applications which claim to be extremely accurate will be showing speed differences of >8kph at least. That is significant when you do top speed tests.

The digimeter on the Pulsars , Apache RTR and the R15 should be fairly accurate. I would not be comfortable relying on the GPS for accurate speed readings.

@digislayer, good attempt there... thanks

Hehhe, it wasn't really an attempt. I just shot it long back to check the stability with which I can hold that particular camera within the helmet at such acceleration levels, and carved the video yesterday out of boredom and obsession

Or i'm sure I can do a better timing, you can see the launch wasn't good at all over there..but I still managed a sub-six second timing of 5secs for 0-60kmph

Thanks bro :P

Well, the shoot's actual purpose was not to clock the timings or so as you can see above..but it accidentally happened to hold my timings, so made a video out of it, my personal best was a 132kmph on 5th gear. It was done on a good tar road that extens after bout 200mts of the very same road that's in the video

chain sprocket

replacing the chair sprocket to a big dia does any changes in perfomance ??

guys who are running two osaram nightbreakers one question ..

Have you tried riding the bike uphill at night ? atleast for 2 hours uphill... if yes did any one have any issue with the battery ?

Killer gave me a nightbreaker recently for testing and i replaced my low beam with the nightbreaker.

I had a night ride to devarayana durga hills with a pillion (with nightbreaker and HID on full time ) and after i reached the top my bike shut down with the engine malfunction light blinking .Battery dint have any juice left . Good thing it just started with a push start without any problem. I dint disconnect the bulb and rode back home without any problem.

Killer had the same issue on keeping the bike on idling for sometime . Has anyone else faced this kind of problem.

**HydBiker** · 02-24-2009, 08:33 PM

One NightBreaker or Silver Star plus one stock bulb - no probs yet.

Two such 55/60 Watt bulbs, trouble after an hour.

I had run in the first combination for quite some time - stock on left and silver star on right. No issues.

Added a Night Breaker on left with Silver Star on right. Started at 11:30PM and drove about 70% of the next 300+ kms with one light - Nightbreaker in low beam (following a Hayabusa or an Innova with speeds between 80 - 120 KMPH) and using both the lights only when needed.

I needed both the lights then - but in about 30 minutes after continuous running on both the lights the battery warning light came up. Switched to low bean and followed a Qualis

**Sandeep_K_Ram** · 02-24-2009, 08:34 PM

I dont think it was to do with uphill riding. It was the night riding - more specifically using the headlamp for 2 hours continuously that might have been the problem.

IIRC the R15 comes with 2x35W right ? And in stock form it should support running both lights in On position right ?

If your nightbreaker is a higher wattage bulb, maybe it drained the battery quicker than the recharging rate. Hence all the problems. That is my theory.

**Aparajith** · 02-24-2009, 08:35 PM

I had battery drain issues with 2 55/60. I tried by removing the two pilots. Still not much of use. The battery would drain considerably when the radiator kicks in. So reverted to 1 55/60 and 1 35/35.

So now you have reverted back to One NightBreaker or Silver Star plus one stock bulb ??

Riding at a good pace shouldn't have any problem i guess. Up hills will have an issue as the bike is always on low RPM.

lets see whats the count here if anyone has faced the similar issue.. I am sure santa will have some fundas here ..

he was running 2 silverstars ..

I rode back 100kms without any problem with both lights on.

The moment my engine warning light blinked the name I recollected is Santa

My trip had no slow speeds. I was on the GQ when I had to use both the lights. I was considerably faster than anything other than Volvos on the road at 4:30 AM.

I had at least a 4 hour running time by then and the battery already lost a lot of power! I was told by a battery technician (based on the type of battery) that the R15's battery takes time to charge but holds a lot of power! Guess that's true.

**Sandeep_K_Ram** · 02-24-2009, 08:50 PM

^ Then I think its definitely what I said.

If both Hi and Low are 35W each then I think the max rating that the bike can support is ~70W for the HL. Maybe a bit more.

If you cross the threshold...battery will drain quicker than its being recharged.

It will be more than that. U have also got to add the two pilots(5W + 5W) and the radiator fan which might run. The tail lamp of 21W also comes into play. So at a time, I think the battery can withstand a load of close to 100 - 110W.

**Sandeep_K_Ram** · 02-24-2009, 08:55 PM

Yes that is why I said "....~70W for the HL"
