    Where the hell did this happen? I had ridden your bike and i know maga , your bike had very very less compression if you rem,i had kicked it a few times when you went your way at zen.The first thing i noticed was the low compression.So compression was never high. The case of valves hitting the piston means only one thing.Valve train failure,spring/s failed. I know and we both know how good Rajesh is ,he'd have never set the cam timing wrong.If it had been so you'd have never run your bike this long.

    1. Bore must have been close to the end of its life ,as compression was low.

    2. I had given your bike a lot of stick on our ride and it had jumped off like a rocket.So either it was fine ,how long ago was that? a year ago?

    3. Due to valve train failure the oil must have been very low and had melted the piston rings.

    4. I know point 3 because i had ridden my bike for some time like that when valve oil seal had given up and that was the reason my engine was opened up and that's when i decided to go for 200cc even though due to MOTUL 300V FS oil had saved the bore when it was running with just 250ml .
    You know what, I had got the bike serviced and oil replaced just two days before the trip, so less oil was def not an issue. The knocking used to happen only in the 4th gear, never did it happen in the first 3 gears.

    When I had this setup done a year ago, I could not kick the bike at all due to the compression, it was that high, once while trying to kick one of my nails had come off. Back kicks were horrible and hard. The compression was so high that setup conked within a 600 kms. Then Rajesh reduced the compression by adding a gasket and it ran close to a year.

    Man ,when you rode my bike didn't your feel the difference? you had told me that the heaviness is because of the heavier piston.That's not the case,it's because of higher compression of my bike that it felt so and your bike has better pick up because of different cam.Remember we were discussing the same with Mr Murthy that day at zen? So high compression was not your problem. and when i was at Rajesh's garage i did inquire about your bike's config and he told me it was very lightly ported.

    Your bike was knocking because it must have lost compression from some time now.The last time you posted here the pic of your plug it was dry.
    So the valve train prob must have started some time after that.
    This happened near the entrance to Gubbi after Tumkur, but I got to tell you guys I gave my bike a lot of stick, I used to prolly revv it above 10K in the first 3 gears.

    I remember telling Nano about the additional gasket under the bore,which worked to temporarily enable him to run....but he still has auto ignition at 8 K RPM when bike is hot....If he doesn't add another gasket soon enough ..another higher CC conversion melting engine parts will happen....
    You had neglected the early warnings the bike gave and ended up 70Kms away with a busted engine...A VERY Sorry thing to note...I know the pain and frustrations of these incidents.Hope you have better luck with the present setup,and enjoy your bike.
    Best of luck
    This time I have gone with the stock 180 bore, the compression has been kept very low, I can just sit on the bike and kick. I guess this setup will be a lot more safe hopefully

      Trust me man,when the valve train goes the bike starts drinking oil like crazy and it's drinking is directly proportional to the revving/stick it gets.

      Within city it might have been drinking less but once you hit the highway it might have drank like crazy and resulting in melted rings.

      I will ask Rajesh about the reason .

      You have done well by going for the 180 set up.But if it's compression is also reduced then your top-end performance will be affected.

      I had asked about the same when nano was installing the 180 bore kit and Rajesh and Murthy sir told me not to reduce compression with a standard RTR180 kit.That is in case of RTR head is used like in your case.Were as in my bike's case the head has been matched. Nanotech's isnt.

        The best way to go is to check the compression and confirming it is as per stock recommendation....it will give you peace of mind,and bike will be safer to go on longer rides.
        Best of luck.

          That's what i meant ,if the head is that of the RTR then there's no need to reduce the compression further.If done then the top-end performance will go down.

            makes sense. will get it done after 500 kms

            • It was quite cold this morning when I started the bike, there was snowlike frost on the grounds ... Could see that there still was some whitish smoke. Not that much and not for long ... I guess it's got to do with the season. My cousin's new Shine emits more white smoke when started and I saw another relatively new Gladiator doing the same... So I assume it's not a problem... but something that happens with the climate. I guess I will let it go at that and stop worrying. Cheers!!!

              • How much can I get the Fiero F2 camchain tensioner for?
                I found out that the camchain itself costs about Rs.800+.
                Next service: Replace head oil seal (anabond didn't solve the purpose so I've bought a new oil seal), camchain&tensioner. No need to open head for all this, only the top cover will do.
                I am yet to find an auto electrician.
                Just riding the bike. It is smooth though the camchain rattles a bit. New tyres make riding very pleasurable!

                    Your bike's not drinking oil But do keep an eye on the spark plug.Yeah like you said ,stop worrying and try to hit the power-band. Both on and off the road. That should take care of the frost.

                      Yes, I heard about Ruby from Gixxer. But coming down to Bangalore for good-that will take another 6 months atleast buddy. As of now, the bike is in excellent shape as far as engine, suspension, battery&paint is concerned.
                      Only things that need attention are this rattling camchain&that wet stalling problem.
                      I wanna get these things sorted out as I'm planning to ride the bike down to Bangalore when I finally come. After riding the R15, I know it will be a patience testing affair, as the cruising speed will be max 65-70kmph, but I'm still willing to take that adventure!
                      So, I might fix the camchain&ignore the electrical issue, then we can go to Ruby.

                      Thanks, I found a TVS spare parts dealer, it was called TriStar TVS or something, opposite Honda spares&workshop in Domalur. He had good stock of most spares. I might buy it&keep it, even if I'm not gonna get it fitted for a few months, till my next servicing.

                        If you want to tour put a 14 or 15 teeth gb sprocket which costs something like 100 bucks .Then you'll be able to cruise at 100 kmph.Once back in town change it back to stock.Simple.

                          +1 - go for 15t & I am sure you can cruise @ 100kmph with it & get back to stock once here

                            Really? No damage to anything?
                            Then why don't people keep it always?
                            Pardon my ignorance, I donno anything about Sprocketing!

                              No damage what so ever if you are not going to extreme levels, like max 1 teeth up or down in front & 3 teeths up or down @ rear

                              Cos most of the time bikes come with best suited sprocket set up

                              My stock set up is 13/39 & now I am running with 14/39 set up & I can easily Cruise @ 85,90kmph all day all long

                              Try it out once & I am sure you will not revert back to stock

                                Really? But will the engine not be stressed if running beyond a certain RPM?
                                These are ignorant or nather noobish questions.
                                I think I need to read the sprockets thread also!
                                After that, I will call one of you guys before coming. But long time to go for that.
