much better if you replace your block with vixion block..at least it is genuine..and about the head assy,i am using a yamaha genuine big valve head..raider125jeigh said:

there you again idoitic pekz!!!! nothin to do with cams!
problem valve tapet or cleance was too loose... your over rev exhaust valve broke
went inside the piston blocked the compression thats why you rod got busted too! no need for valve pocket...
good thing i checked mine yesterday or that could happen to me as well because my valve seal wasnt the right one so had to change it
look at ur head gasket too much tribond which i had too...
too much open pipe does as well that no return pressure thats what my mech told me prone to valve float..

just and advise guys if you feel something different or hear something unusual to your bike dont hesitate to check it asap.. my mechanic told me that those things will happen to my bike when i went online saw this i was relieved and felt sorry as well to our colleague.. lets help undah find cheap parts for his bike...
wow the most horrific picture ive seen 
the picture shows how STRONG T135 FORGE PISTON is
theres no hole in the piston after too much battle with the valves
anyway, it looks like the head was Melted?
its caused by too much heat? lean carb maybe?
ps:
dont throw that cyl head bro, make it as a souvenir and display in your living room

I think its not only cams did this, several factor,first overrev, second lack of engine oil, if noticed the cyl wall has scratches and lines,one factor is that the fuel mixture is lean....
i am just basing it on my previous experience and the pictures.
most likely you need a new head, block , valves and con rod

Lean mixture, that is the most probable culprit for this one... 2nd, the damage on your head and piston is either you tend to crank the engine after it ceased OR, a foriegn object got into your combustion chamber... But definitely your carb setting was inaccurate... If you could provide more info regarding the changes made, we should be able to point out what happened... Put the valve clearance and cam out of the equation, consider valve float if your engine ceased during hard acceleration on 1st, 2nd and 3rd or you missed shift at hi-rpm... Who's the mech if I may ask?

thank you guys for all your shared ideas on what possibly happened to my bike. so here it goes, it all started when my bike had a broken crank because of a loose chain so we have to break the engine for a possible solution of having the broken crank to be repaired by a tig weld then after that i had my broken crank fix and put the engine back together again but after that i had again a problem in the head of my engine because the water and the oil blends together so by the time i had to change my oil the color of my oil was grey because of the water mixing with the oil so i had to go to yamaha 3's shop to buy a genuine head and block gasket for the problem to be resolved. after that i put a mineral based oil for washing then after a day i've change my oil again and put a seminsynth oil " CASTROL POWER 1" because we are having a ride to MARILAQUE and i'm going to use my sniper. i never had it tuned because my manifold also has a crack and no time for replacement because of the ride earlier the next day. then on the time i was riding my bike it has no power at all then i start laughing cause im only doing 80kph on 3rd gear WTF! then come's the over reving because it has no power. then all of a sudden while doing 80kph on marcos highway i heard a scorching sound "KKKEEEERRRRRKKK" then after that my engine shut down. i hold my clutch and get on the side of the highway. i started to think. OMG! what happened. what is that sound i heard on my engine. so i had to push my bike from antipolo - makati using my feet with a help of my friend and his bike. then the next day we had to check the engine for the possible problem then "poof" the worst thing i've ever seen on an engine. gaaaaaa.. another major expense again for my bike.
@x project - sometimes i only DIY my bike but my mech was only my friend.
@traxxas - thanks for sharing your ideas. yeah i will have it as a souvenir. haha.
@hearthrob - can i have one of those cans? haha.
to all my friends and co-forumers specially those who are expert in T135 thank you for all your comments and ideas.

Sweet Jesus! Of all engine components, crankshaft is not supposed to be welded back to resolve the issue bro... Lots of complication and your engine is just waiting for the inevitable bro... You have to check your crankshaft if it is still intact... If the other half gave in then chances are, your crank's magneto-side part broke and stopped while running then it sure will make way for piston - valve collision because of the inertia regardless if cam/timing chain is still or no longer connected... If your crankshaft is still in one piece, take my advise, change it before rebuilding your engine again... Expensive but will save you more troubles and more expenses ahead... BTW, your broken intake manifold might have caused the engine to run with lean mixture...
