    You should be happy to find another guy interested in modifying bikes here.
    Yes I am keenly watching the thread as usual....still waiting to learn new things....and this thread is food for so many of us..
    Nano's problem is intriguing,...trying to figure out what could be wrong,since he says most of the likely areas are ok.

      I think,nano meant that the bore and rings were ok when he had last checked it.Which was to get the head matched to that of the bore size.But since then lot of things have happened.

        Yeah, and he had gone back to stock rotor windings too....there had been so many mods ,done and undone, I lost track of his present setup to understand his present predicament.

          I very recently got the things checked again when i changed the valve oil seals, this was much later than the pics i posted here and after fouling 4 spark plugs.

          Even after the new seals i did foul another plug.

          Surprisingly though the replacement plug (the one i am running now) is running okay.
          Generally my plug lasts upto 90~100 kms, but this one i assume has run around 200 kms now and its in a decent shape.

          The last check of bore and rings was 350~400 kms back, everything was okay.
          The clutch plates (2000 kms or less) has lost everything and now bike slips clutch more than ever.
          Got the oil topped up today itself and had to put in 300 ml.

          I checked everything, from what I've learnt so far, the bike isn't leaking compression, the timing is perfect too, apart from an insanely critical clutch plates nothing else (performance wise) is a problem.

          It drinks oil and spits the residue on the plug, but recently that has decreased too, now it giving a strange tappet noise from last 2 days.
          I hardly ride my bike, my dad rides it very rarely for say 5 kms max.

          I did go to the mech as i mentioned and everything is alright, but still it has a lot of problems.
          I really don't know what to do.
          Giving a lot to a fiero.

            the new pulsar 200ns comes with 72mm piston.. if i can source a piston and if the piston height matches, i will try it on my RTR cylinder(I have an extra cylinder).. Then it will displace 235 cc..
            i'm not sure what type of piston does the p200ns uses.. I wish it is a dome type piston...

            @gixx

            can u tell me whether your sleeve can hold a 72mm piston?? Stock sleeves are 70mm which can be bored till 69mm..

              The current sleeve can take 68mm max i think and not more.But as i'm sure you know there's lot of space to take it to 72mm bore as well.That would need a new sleeve though.
              Mr Murthy of ZEN Shakti TVS had shown me a forged jap 67mm piston with a matching cast iron sleeve and ultra thin rings set(All Jap).Which he intended to install on his v-twin fiero/drag fiero/RTRs.Maybe you can try that one,that was super light and strong.

                Looks like your piston has taken a beating.. If oil seals have been changed and there is no compression leak, the only way through which oil can enter into the combustion chamber is through the piston.. My predicament is your crank bearing is weak and shaking.. This causes piston slap and oil to enter into the combustion chamber.. How many kilometers has your bike done?? Have you ever done a crank overhaul before??

                  Thats some info.. If possible, try to check whether the piston height of Fiero and P200 ns are similar.. I know it will take some time to get the piston, but it will be a great help.. I'm planning to get an RTR or a Fiero to check this out.. Fieros are quite cheap in here.. i got mine for 10k and i'm having another offer for 12 k..

                    I have been assuming that his mech, like the norm is , always checks the crank for play whenever the engines dis-assembled.I had told the crank to be checked for play long before as well when he was installing this kit.

                      Well,if you can get one that cheap,then go for it.If you're in no hurry then you can certainly wait for ns spares to come out,I'll try to find out as well.But,i think in drag-strips this jap forged piston kit is the ones being used on fieros/RTR's.

                        ok.. If i get another fiero, i'll try that piston.. But the Fiero i already told you that is running a 68.75 mm Matiz car's piston is way too impressive.. i thought going for a piston that is larger than that would envy that guy.. He often boasts about his bore size and calls me for open drags(Which i know my Fiero won't keep up with his , but in dirt races he often tastes the mud flurrying out from my rear rubber...

                        • @PSR, p200ns Bore X Stroke=72 x 49.. Same is the case with the Indian version of KTM Duke 200...

                            Sure thing then,i got what you mean.Wait and go for the biggest bore size.I'll ask around and let you know whether any forged piston of 70mm or more is available.

                              Yeah thanks for correction the Indian KTM and Pulsar 200NS share the same bottom end and bore X stroke is 72 X 49 mm...

                                Thanks a lot.. I wish i could become the best tuner in coimbatore.. I surely need some help from you guys.. i'm also very happy to get to know Gixxer who seems to be a pro with Fieros.. (I'm good with Rx as well ).
