wow! thats awesome man.

Few questions first:

porting doesnt take as much development resources as the rest.
So, is joel serious about bringing on the big bore, cam shafts and exhaust? or is he just testing the waters with this porting work?

And what is Joel's opinion on this engine now? Did he say anything specific about it? Has any other owner had similar work done?

Screw the highway.... take it to the hills. Rip it through Nandi and let us know how it feels. any improvement in the mid range?

He neither mentioned about the bigbore nor i asked him...As of now am not sure whats in store for us in future..Lets hope for the best...He said the engine is quite good and has some potential,
I feel the wieght of the bike is killing the performance..Iam working on getting rid of the weight now...
Removed the saree guard today and was searching for a suitable naked chain cover for GS...
can anyone throw some light on the part in bold?
Mine is the first GS150r to get the mod...

Coming back to my ride..The acceleration has increased a lot now,0 to 60 is quick....
I redlined in all gears today(except 6th)
2nd-69kmph
3rd-93kmph
................
and the top speed in 5th was 126kmph...
What is the stock figures for each gear?

An increase of 10% in FE and considerable increase in power of the bike at the same time? The same question the persons like me always ask: Why are the engineers designing the bikes - including GSs - not considering this possibility of modifying the ports? Strange.

2009 model GS reaches 69 kmh in second gear, 93 kmh in third gear, 111 kmh in forth gear and 126 kmh in fifth gear at 10250 rpm. At the same rpm, it will be 145 kmh in sixth gear and, that too, without any modified ports.

If you can reach 12000 rpm, the speed will be 47, 81, 109, 130, 148 and 170 kmh in respective gears. No modifications are needed to reach this speed if you can push the bike to that extent.

Have you ever checked the fuel efficiency of your bike in the proper way?

Jai Joel! He too is trying to live and he has the right to do so. But when it is on the expense of others, it needs to be questioned.

I have not tested the Mileage yet..The main thing that is improved is the acceleration.... Practically 145kmph is not possible in 6th,as we cant redline in 6th... Also there were lots of cross winds today...so you cannot come to any final conclusion yet...

The magic word is... "RELIABILITY"

If you eat a piece of bread slowly it will last a while, but instead you gulp it down it'll get over soon and there's a possibility that you'll choke to death in the process.

Though the thrill of it is priceless.

All km/h numbers are in center stand mode rite

How did you come to this conclusion without checking it? Here you are ‘feeling’ that the bike is accelerating quickly and it is due to the psychic effect the modification has on your mind.
If it is not so, it need to be proved scientifically.
The speeds I have mentioned are theoretical but are practical on road if you ride the bike at that rpm. E.g. GS reaches 33, 57, 77, 92, 105 and 120 kmh in first to sixth gears on road at 8500 rpm, where it produces its maximum power and it is not impossible to reach that speed and any kind modification is not needed to achieve it.

I cannot understand what you mean. Do you think that the FE and power/performance of a bike can be increased at the same time? If yes, how is it done? Please come to the correct point instead of beating the bush.

I have ridden my bike and am feeling the difference,so its just my opinion about acceleration..You need not worry about whatever effect the modification has on my mind...what are you trying to prove anyway?

If you want me to measure 0-60kmph in so called "scientific way" using a speed gun or a Gps device,its not possible because i don't have any resources required for the tests..........

Everything is because you have posted the results of/your opinions about the modifications on your bike in a public thread where all of us participate in the ongoing discussion.
I am not at all worried about the effects of the modifications on your bike but expressed my opinions as you yourself did. Please don’t be felt insulted.
