    Gixxer Bro... the good state of the carb that you mentioned is the result of my messing around with the carb... now that it is fine... I'm not gonna let even the mech fool around with it. It is tuned to 2.75 revolutions anticlockwise from closure (the leanest point).
    How can you be sure that it wasn't in this state of tune before you started playing around with it? Did you check the plug state before starting tuning it yourself and if so what was the color before?
    That 2.75 rev from closure you mentioned about is i believe,you learnt from the suzuki gs150 thread right?
    Get this straight ,tuning a carb is a setting per bike and it can't be generalized for all the bikes with carb of 26mm.Do you know the jet sizes of the gs150? or what the emission norms our bikes are tuned to meet and what the gs150 is supposed to meet? GS150 is a different engine in comparison to ours and that 2.75rev from closure is not a cast in iron rule for our bikes.Carb settings are per bike for the conditions it is used in.You ride in high altitude and how can the setting of a guy say who rides at sea level be the same?So the performance keeps on varying depending on weather ,altitude,fuel, air filter state etc etc.
    There's a reason as to why Fuel injection technology is being used you know.

    • @NANOtechnology: Check the sprocket rubber, that also causes a lot of jumping in the gears.
      I guess my bike's rear Dunlop Geo Cruiser 100/90/18" tyre needs a replacement soon. Though the threads look great even after 4 years/32K kms., I guess the rubber has become weak, so rough roads are creating problems for the tyre, especially with pillion. I got another patch done to the tyre from the inside, this weekend!
      Poor bike-I felt sorry I could not service her, so gave her a good wash.
      Next month (after shifting residence) I will definitely give her the much needed service, as well as carb.etc.tune up&head packaging replacement, as discussed with you&gixxer_junkie_m.

      @gixxer_junkie_m: Since I am postponing the service, I wanted to be sure the oil is fine, so I took a pic of the oil level since I have done 2.8K kms.I will attach that tomorrow. The oil does not yet feel coarse to touch.
      Please give me your view on it later.

        Gixxer bro... while it's true that I learnt bits and pieces from here and there, whatever I have really learnt comes from practice. It's absolutely true that xBhp has given me the confidence to even try these things on my own. I might have never attempted such a feat. However, this time it was through trial and error. I tuned it to 4.5 revs and the result was too much drinking. Less resulted in very little pickup. So I settled for the 2.75 revs. I really wanted to know the approx tuning of carbs at this altitude. But like you said tuning is subjective and every bike will have a different setting. I guess the altitude, wet monsoon weather and the newness of the piston has resulted in that particular choice. I could try to give it 3 revs to get the power up a bit after a few more days. Now that I am gaining more confidence, I can afford to be more experimental. I have no idea about the GS carb pin or emmisson norms... all I know and feel happy about it is that this setting works for me and I can confidently reset it whenever I want even if the mech fiddles around.

          Listening to the engine note ,then making sure there's no knocking and riding the bike after each change is the norm.But equally important is to read the plug.When i say reading the plug ,i meant as a layman and not like an expert with a plug reading kit.So while tuning the carb make it a point to check the state of the plug and if the plug is of the color you mentioned or darker then you will be fine.Just make sure that the plug doesn't turn a shade of parched white.

            Sure thing man.As long as the oil level hasn't dropped drastically ,there's no need to worry .Judging the state of the oil from its color is difficult.The best thing is to judge it by feeling how smooth the engine is or how much noise the engine is making.If the noise goes up after riding the bike for ,say 10km and if the oil is over 2k old .Then its time to change the oil.

              Gixxer bro, You are right about the above. Engine note is so much better these days and nocking has reduced if not totally eliminated. I guess a little adjustment to the clutch cable will help. I had to change the throttle cable and now the engine speed reduces when I let go the throttle. The cable had become faulty, used to get stuck and did not settle back. Exhaust has become very clean with no residue. The bike feels responsive. I feel it just lacks a little bit of power (mid and top end). Now tell me when do I service the bike next now that the 500 km (done at 600 km) servicing is done. Thanks to you guys for building my confidence level. I went for the engine boring and piston change. So you see... the forum has helped me a lot. Thanks!!!

                Yes, if you remember thats what is happening to the bike, after riding for a few kms. You had stated the reason as lean mixture setting.
                I will get all the things done at the next service, but just attaching a pic of the oil level FYI. I felt happy that it did not feel coarse to touch, even after almost 3K kms.!

                  wow chief, good to see such an improvement in your bike as well as your knowledge..
                  get next service done at 1200-1500 range, and then push as hard as you can, your bike will perform best as it can.
                  you didn't change the clutch plates ??
                  get it done if the older plates are more than 15000 kms old...
                  see it there's any adjustments needed to tappets as they may decrease your engine knocking...
                  and after your next service keep doing services on regular basis after every 2500 or 3000 kms...
                  ride safe bro...

                  its 3k still the oil hasn't lost color, its strange, it should be darker than this as much as i know, but since your spark plug is fine, then i think its good to go...
                  when did you last change the oil filter??
                  FYI my oil turns black after 2500 kms...
                  and coarse to touch after 3000 kms, i do change the oil filter almost everytime i change the oil...
                  for me this color (the pic attached) happens at 500 kms itself..


                  @ all

                  I've been initially counting days, then weeks, now almost a month to get my 180 stuff done..
                  i didn't wash my bike from last 4 weeks..
                  i didn't service my bike which is due 2500 kms now...
                  as i thought soon I'll change piston, block stuff..
                  last to last to last week vishal was out of town
                  last to last week were festivals.
                  the sat which is gone now had a prob of the mech as he went to visit somebody..
                  next week Vishal has some office thing..
                  next to next week i MAY get it done if my destiny is not bad..

                  damm it feels strange for me to ride a bike which is hungry for service, i dunno i feel that why to spend if i am opening it anyways...

                  besides from last two days my bike has been pissing petrol from the carb, today i tapped the carb as vishal suggested and its good to go now, dad is shocked as i lost 4 litres of fuel in 1 1/2 day, all that drained..
                  i hope i get stuff done soon..

                  i more thing gixxer and sarvajit..
                  i got my chain tightened yesterday, the downshift noise is gone now..
                  however the chain was not loose, but its too tight now..
                  i think the crash and noise was a co-incidence. it had nothing to do with it as its gone now..
                  i think my chain sprocket set needs a replacement. Hope i don't brake the chain before completing 2000 kms of run in of 180cc...
                  Giving a lot to a fiero.
                  Expecting a lot from a fiero.

                    ================================================== =====

                    NANOtech, I have a new set of clutch plates and a cam chain with me. The mech says these are fine at the moment... guess I will be replacing them in the 1500 km servicing. However I will be paying the mech a visit in about a week to get little things adjusted. For the moment, the bike is doing great. Monsoon is still on and the roads are muddy. The bike needs a wash every other day. Sometimes I become busy and too lazy to get the bike washed even for a month . Thanks to all of you for your help... learning to be a better biker everyday. Cheers!!!.

                      Oil looks to be in pretty good condition,so you can go on using it till the service.In fact at the moment my bike's on yamalube 15w50 and its done 2k and it also looks similar in color to yours.

                      Yeah dude, waiting sucks big time!! Its been the same for me as well, I've been waiting for the carb since almost a month now and i feel like taking my money back and buying it from the junk yard.

                      Yeah bike's are like girls on occasions ,not all the time. So you can never be sure as to what's on their mindYou wreak your brains out thinking as to what could be wrong and HEY PRESTO!! everything's fine!
                      Seriously ,yeah i had guessed as much.Most of the small gear shift problems are to do with the clutch setting and the chain slackness .Anyway its a good thing the prob disappeared .
                      My bike's acting up once againThe same old electrical issue,man!! i had thought fiero's were less tempermental .
                      I am telling you dude, change the handle to that of a FURY or FZ it will improve the handling and road grip of the bike under heavy braking.Another thing under sudden braking maneuver ,always use the front brake most and use the rear brake lightly ,it will avoid a high-side or the fish tailing you experience with all the bikes you have tried which have front ward weight bias.
                      Cant blame your braking style,because fiero and f2/fx have weight distribution which is suited for dirt track riding rather than street racing.The solution?? Switch to a lower handle and see the difference.It might save your skin some day.

                      • Guys ,lowering the handle increases the weight on the front end and it improves braking and another reason for loosing the front end on fiero/f2/fx due to use of disk brakes are because of the high handle bars they have.You won't be getting enough feed back from the front wheel due to high handle and on sudden braking front end will loose grip.Think about it,for 200 bucks you can drastically improve the bike's handling and road grip.As i said ,it might save your skin some day.

                          Yeah engine knocking is the thing which reduces the engine's life.Try to reduce it if you're not able to eliminate it completely.
                          No need to thank us man,we all are learning from each others experiences.

                            for me this color (the pic attached) happens at 500 kms itself..
                            It was a bit darker than this when I removed the dipstick for the 1st time, then tried again to get the accurate measurement. Moreover the light reflection also makes it look lighter! But there was no discoloration last time when I checked at 2K kms.Now its around 2.8K kms.
                            I also get the oil filter changed at almost every or maximum every alternate service. It hardly costs anything, so why not!

                            @ All
                            Damn it feels strange for me to ride a bike which is hungry for service, I dunno I feel that why to spend if I am opening it anyways...
                            I have the same feeling, since I will also be opening the head at the next service. You are right-it gives a slightly sad feeling to be riding a bike which is hungry for service, but in my case it is lack of funds.

                            Besides from last two days my bike has been pissing petrol from the carb, today I tapped the carb as vishal suggested and its good to go now, dad is shocked as I lost 4 litres of fuel in 1 1/2 day, all that drained..
                            I hope I get stuff done soon...
                            No issues-it will be done up easily. Don't park the bike on the side stand when you have more fuel in the tank. Also get the sediment bowl cleaned once.
                            In the initial days I had a petrol tap lock&installing that made me lose the small sediment bowl that comes on the stock tap. The bike used to leak petrol whenever parked on side stand. I got the lock removed later&then it stopped. But still as a practice, I always switch the petrol tap to off position while parking nowadays.
                            Speaking of pissing, my bike puked out a lot of water the other day after washing, I was a bit surprised, but then I remembered that the drain pipe had fallen off last month!
                            The amount of water that fell out would atleast be a litre (I washed the bike well after a couple of months, hehehehe!)

                            1 more thing gixxer and Sarvajit..
                            I got my chain tightened yesterday, the downshift noise is gone now..
                            however the chain was not loose, but its too tight now...
                            I think the crash and noise was a co-incidence. it had nothing to do with it as its gone now...
                            I think my chain sprocket set needs a replacement. Hope I don't brake the chain before completing 2000 kms of run in of 180cc...
                            No issues-it will loosen up within 2-300kms.don't worry.

                            Oil looks to be in pretty good condition,so you can go on using it till the service.In fact at the moment my bike's on yamalube 15w50 and its done 2k and it also looks similar in color to yours.
                            Thanks. My R15 is running on the same oil, needs a change badly now, since I've done over 4.5K kms. with it. I heard Yamalube full synth is also available in 10w40, waiting to try that on my Baby R1!
                            Btw, I had tried Petronas full synth 10w40 oil&it just didn't suit my bike-how does yours respond to semi-synth oil?

                            I am telling you dude, change the handle to that of a FURY or FZ it will improve the handling and road grip of the bike under heavy braking.Another thing under sudden braking maneuver ,always use the front brake most and use the rear brake lightly ,it will avoid a high-side or the fish tailing you experience with all the bikes you have tried which have front ward weight bias.
                            Cant blame your braking style,because fiero and f2/fx have weight distribution which is suited for dirt track riding rather than street racing.The solution?? Switch to a lower handle and see the difference.It might save your skin some day.
                            Agree to that. I feel it all the more since I ride an R15 most of the time.
                            But nowadays I am losing the front more often since I am still running the stock tyre (53K kms./6.5 years), but since I have a new disc plate&pads, the bite is damn good, but there is hardly any feedback from the tyre.
                            Moreover the rear rubber has lost its strength, though the threads look like new! 33K kms./4.5 years&2 patches inside the tyre itself. I'm planning for new tyres asap-Dunlop Ezee Cruiser 2.75*18" up front&Dunlop GeoCruiser 3.00*18" at the rear.
                            God give me some 10K bucks extra to spend on both my bikes-they are crying out for attention!

                              What i have learn't from my experience is that MOTUL 300v 15W50 factory line FS is THE best oil available in india.
                              I have tried all kinds of oils .I used to change castrol power 1 every 1000kms as it used to become thin and was a total waste of money.Then i switched to the MOTUL 300V 15W50 fs and the bike was silk smooth even till 5k kms.PETRONAS sprinta fs is smooth but oil level drops quite quickly.
                              YAMALUBE ss 15w50 is motul 3100 ss i believe and it's good,not as good as motul 300v obviously.But the engine note became a bit gruff after i switched over to the yamalube 15w50,the engine is smooth mind you.

                              The r15 and RTR are my kinda bikes.Both in terms of riding position/weight bias and the top-end performance oriented engine character.
                              Yeah i agree with you,dunlop geocruiser is a very tough/durable tyre and i intend to switch back to the 3.00 18 tyre for the rear too.

                                Yes you are right about Yamalube being repackaged Motul. In my case Petronas level dropped drastically on my Fiero&even caused the gasket to leak, same thing that happens with Pulsars running on fully synthetic Motul 300V. Though that is a great oil, no doubt.
                                When you switch from mineral to semi/fully synthetic engine oils, the engine note does become a bit gruff, but the heat management difference is clearly felt, especially when you come back to idling speed after a high speed run!

                                Yes, the threads are still looking like new even after 4.5 years/32.5K kms.
                                but I guess the tyre has lived its life, cannot take more chances with it now.
                                Though more than that, I'm waiting to see the difference in top end/accelaration after switching back to stock size!
