what do u mean by adjustments ? what kind of adjustments would be to the head lamp ?

Yes... if the mode is either ECO or PWR. I didn;t mention it as that was discussed earlier.

Did you check if there is a nut or a screw under the headlight? Many bikes have the headlight beam adjustment bolt there. The manual generally mentions such stuff... may be some owner can post a scan / photo of that page.

I checked Feb 09 Bike India issue yesterday, where they have compared GS150 with Unicorn, pulsar and for some reason, Achiever. There they have clearly mentioned that the modes control only lights, and no mention about the mapping. They say that in Eco mode, light starts blinking at 4500 RPM, and stays on after 8000 RPM. In Power mode, it just flicks on after 8000RPM, indicating you are in powerband and close to REV limit.

Then what do you have to say about HYDBIKER's post.......

^^^ Sorry I don't have the technical knowledge. Just quoted what Bike India said!

EDIT: If indeed the mode changes the mapping, then what does the third 'blank' mode do? What mapping does it have? Even though I would love to see the mapping done by the modes, I am more inclining towards Bike India's opinion, unless someone proves otherwise.

46 the Greatest ever

the eco and power mode only work as mentioned in Bike India mag....and there's nothing more to it...

yes,im my suzuki heat also the same occurs,my dealer told the same what u told, and it is a +ve thing,not to worry,he told.

hey guys, da thing that u saw on the carb is a THROTTLE POSITION SENSOR......remember even the yamie fazer had it as YTPS??
the ECO and POWER modes are only cosmetic and have nothing to do with Fuel Mapping.
TPS gives inputs to a cdi which controls the Ignition mapping...it has nothing to do with fuel mapping......i dont think that we can do fuel mapping with a carburettor. had that been possible, why would have anyone used Fuel injectors.....we can only supply an almost constant fuel ration with a carburettor.
please correct me if im wrong.

Ok now I think I have to dig in.......

well what do you guys understand when you say Fuel mapping....Hydbiker, KK_rtr????? If you ask me Fuel mapping is a theoratical graph that displays the optimum fuel enrichment at a given RPM. This fule map is used as an input for EFI (Elecrtonic Fuel Injection System) for regulating air/fuel mixture. now this EFI is not used in bikes (except the RTR-FI and may be FZ as well.....) but our good old carburattor is been modified to perform better......so comes the TPS (THROTTLE POSITION SENSOR......) which is what we have in GSR (not sure abolut fazer)....
Throttle position sensor sends signal to the engne controll unit (ECU) which in turn controlls the ignition and fuel injection timings which again is what Fuel Mapping is. So saying that we can not do fuel mapping with carburettor is wrong.

Now what I believed was or may be I still believe is that the ECO PWR mode we are talking about is electronically connected with the TPS sensor and adjusts the TPS depending up on the mode choosen.........which in turn adjusts the fuel mapping. Like for eg if the TPS idealy directs the ECU to do x% of fule mapping at a particular throttle position it would differ if the PWR mode is selected and same for ECO mode.................Thats what I think......I hope I made some sense....

Again I might be totally wrong for the latter part but the former one I presume is correct.
