Most certainly!!!

In the meantime, my bike has now completed 5,000 kms and 1 year of running. I have finally been successful in getting a G-Tech Fanatic Pro RR data logger . My cousin has confirmed that he has received it and will be carrying it with him. So I should get it by this weekend.

I will post a full report of the testing with data logger results along with a round up of the 5,000 kms experience.

Finally !!! After 8 frustrating months I have got my hands on a GTech Fanatic RR data logger. I was on the verge of giving up on the GTech and ordering a Racelogic Drift-box, however, I get a call from my cousin telling me that he has received the GTech. After that it was a matter of waiting patiently till someone from U.S. was coming down (that took another 2 months). Now that I have it in my hands I am an eager beaver to start testing. Unfortunately, its going to be couple of weeks before I can do it as I have a very heavy work schedule and also have guests (one of whom carried it for me) who will need to be entertained.

Now coming to the GTech Fanatic;

The packing consist of 4 items; The GTech Fanatic data logger with a micro SD flash card (installed), the SD card USB adaptor, a power cord and suction cup with mounting bracket. There is also a quick start guide of about 10 pages. A comprehensive manual in PDF format is available on the GTech website and is required as the unit is loaded with lots of features. There was suppose to be a CD with a software called PC Analysis System Software (PASS) but the same was missing. However, that is a minor issue as the latest version of the software is readily available on the website and is a reasonable 12 mb file (only problem is that its a .exe file so will need to load Windows on my laptop ).


The GTech Fanatic Pro RR data-logger with power cord and mounting bracket.


The GTech Fanatic Pro RR unit.

The GTech is a surprising compact and small unit. It is a unit that is so small and light that it gives one a pause of thought on how fast technology is developing. Consider this fact, the GPS system become fully operational and open for civilian use only in 1994. Wide spread use of GPS really took off only at the start of this millennium. One can only shake their head in wonder as to what will be the next technological step.


A small and compact unit.

Compared to the Racelogic Driftbox, the GTech has less features, but it is still a powerful measuring instrument. The one place where Driftbox really scores over the GTech is that it is a truly independent unit not requiring any external power source as it has a battery pack as part of the unit.

Since the GTech requires a external power source (a DC power cord with a cigarette lighter adapter), I had also ordered a Powerlet 12 DC cigarette socket system.


The Powerlet Cigarette Socket system.

I plan to test my bike along with a stock R15 at the same time which has completed 5,000 kms to ensure that a common base for comparison is obtained as many of the variables are neutralized to some extent.

Now where in this town will I find a kilometer of lonely, level and well asphalted stretch to carry out the tests ??? Also any volunteers for the stock R15 ???

Experiencing it daily home-office commutethough mines only an exhaust job,still it has changed a lot.I especially like the look on the faces of other 220 stock ownerswhen i pull out cleanly.The mid to higher power band area is where i start looking like the evil Mutley laughing.

@abhimanyu-looking forward for your updates

Abhimanyu, This was a very interesting read, spent a good time going thru the posts....very well written with great details and pictures. Joel seems to be doing a great job and hats off to him....I hope I can meet up with all you guys in my next visit back home....Indian biking has come a long way and would like to share some of the experiences with you guys.
Waiting for the update on the data logger finds and a video

The Gtechpro Is very handy. One of best and compact performance tesing tool.
Its very close to the driftbox in terms of data accuracy. The Gtech has an added advanatage of comparing upto 5 runs at once.

Hi all, sorry.. haven't been able to post anything on the R170 as i have been travelling constantly.. finally got hold of it tonight so shall do some tests from tomorrow. Will be in blore from 14th feb till 17th so will try and nag Joel soon to have a look at the FZ kits from RC.

Anyways, my friend finally got most of the parts replaced/repaired on his R170. Unfortunately, Kamla Yamaha didn't have the following parts; speedo sensor which went kaput again, rear plastic panels, coneset, handlebars and new fuel pump which has been the source of power drop problem when driven at slow speeds below 4k rpm and needs replacement as soon as possible... today my friend ended up doing a small drag with another Daytona Kitted R15 and completely destroyed it.. In just matter of seconds, Joelled R170 overtook the daytona kitted R15 and just kept pulling ahead.. the Daytona guy stopped his bike right next to him with a confused look on his face ! He asked my friend looking at Joel's exhaust... "with just the exhaust it is so fast??"

will post my results soon.

Cheers

He he he ..... Shiv, not fair, you are playing with a loaded dice, the poor guy must still be scratching his head trying to come up with a possible explanation for the whole episode.

I am still searching for a good straight & level stretch of road with proper asphalting which is fairly secluded for my timing runs. Also looking for a stock R15 to run and compare against.

Meanwhile, I did a couple of trial runs to check out the data logger and the camera. The motive was not to do all out runs but to vet the working of the data logger and the camera and to get familiar with their operation. None the less, the results were very interesting.

Here is a clip of one of the runs:

R15_Run2 - YouTube

Couple of things to note over here (as you can see from the clip); first, there was way too much of traffic for me to really to a nice clear run. Second after couple of runs, I started attracting way too much of attention with guys on bike trying to follow me. In short, it was becoming too dangerous to continue.

About the run;

0 - 100 in 10.4 seconds. Not exciting? Well, consider this, a stock bike with a 50 kg rider will do a best run of 13.65 seconds (V-box results) with limited fuel on board.

Before the runs, I weighed my bike at a digital weighing bridge. The results:
1. Full wet weight (with a full tank of fuel, full coolant tank, oil, data logger, camera): 130 kgs.
2. My weight with all riding gear (includes helmet, riding jacket, body armor, riding shoes): 70 kgs.
3. Total weight: 200 kgs.

That is a difference of 3.25 seconds with a 20 kg heavier rider and a full load of fuel (note the fuel gauge in the clip) without even getting a good run!!!

The bike also had 1 psi less air in the front tire and 2 psi less in the rear tire.

As is apparent from the clip, there was no way I could have done a better run with the type of traffic I was encountering. By the time I was reaching 11,000 rpm in 3rd gear and ready to shift into 4th gear, I am forced to letup as there is traffic ahead.

I suspect that with a good run I should be able to shave off another second and a half to reach the low 9 seconds mark.

The net Horse Power indicated for the run was 18 HP. Once again, it will be much higher once a good run is done (I suspect couple of ponies more to 20HP). The net HP is different from wheel horsepower as measured on a Dyno. As you know wheel horsepower is always lower than engine horsepower (measured at the crank). Similarly net horsepower is lower than even wheel horsepower. Net horsepower is the actual power available to accelerate the bike after all the power losses have been subtracted (which includes, transmission losses, aero drag, etc).

I hope to run couple of more runs by this weekend and post the results with the relevant graphs.

Brilliant Job.

Is it possible to upload a Dyno chart with this current setup?


Instead of hitting the rev limiter in initial gears, I hope the sprint would be faster if you maintain the bike in the RPMs where peak torque is achieved. Which means gear shifts between 8K-9K in 1st 3 gears will faster I suppose, need your thoughts on this.
