@x project
bro what does he mean when he said crank? crank pin? crank shaft?

@ts
bro what specific crank was broken? can you tell us what broke down before you 1st opened your crank? thanks..

 

[Undah-Bone]

Im under the impression that your crankshaft was welded back together, did I understand you correctly bro? Is there something wrong with the connecting pin that you had to have it tig-weld or just the shafting was broken?

here is the broken crank that i'm talking about.

and here is the picture after having it tig weld and rebuilding the engine again.

i know there's a lot of possibilities on why does it happen to my engine and it will serve as a lesson for me and if ever i will have my engine fix again i will go to a certified mechanic who know's everything on my bike to avoid having the same problem again.

there is a bit of a confusion here.

I believe that what was broken on this bike was not the crankshaft or any part thereof.............

it was the crank case that was broken and it was the one that was tig-welded.

your correct sir..

Your sniper wants to be taken care of.. sniper is jealous with your new MIO , maybe that’s why.. hahaha..
I heard Raymond of Yamaha told us that if you have a lean mixture (carb) it might affect the piston churvaness hehehe..
Maybe it was not fix properly that’s what I could think of.. no worry I know this is the reason to make your sniper a MONSTER

has your bike been bored up?

Damn man, Im so freakin confused right now LOL... The crankshaft is inside the crankcase bro... If your CRANKCASE is the one that got broken, then forget what I have posted previously but take the "CAMSHAFT" out of the equation... Lean mixture is a possiblity that caused your head the meltdown... I would like to know if you tried to "crank" or tried to start your engine after it ceased or stopped bro... If you did attempt to restart your engine, then it will explain the damage on your piston and cyl head after your ex valve broke... We are trying to find the cause of the problem so we need to get a hold of precise info as to why did this happened...

I also noticed the threebond sealant on your engine... Did you guys change some stock parts on the on the engine's inside components such as the trans?

Based on the pix posted above, you got that right brother...

 

[jubilum]

if you have mixed something in your fuel? for better combustion.. you have over mixed it.... have you upgraded your engine to a higher BHP?..... have you changed your sprockets to a lower speed??? SIR... your engine damage is caused by any of this.... YOU'VE GONE BEYOND ITS MAXIMUM LIMIT.......

 

[X1rCJ]

wew..learning..

 

[marvymavs]

I agree with Sir X Project. A leak in the intake or exhaust manifold will reuslt in improper a/f mixture. causing it to lean out. And Crankshafts should not be welded nor attempt to repair like pressing, etc. Imagine the stress it takes during the engine operation.

Bro, you might confuse the TS... FYI, sprocket settings will not cause the said issue... Over rev or hi-rpm might but it is not an issue with the final drive setting... Even hi rpm or over revving will not cause the cyl head components to melt... Not just my 2 cents but it is a fact... Regards...

i never replaced anything on the engine such as trans. we just put a threebond to avoid leak after putting the engine back together.

another question.. as you can see my connecting rod is damage too.. what else might also damage inside my engine?

Even if your connecting pin might still be in good shape, I will still suggest that you replace your conrod as well as the connecting pin... You can get an original conrod set with pin bearing and connecting pin at Fastlane... Ask for Freddie, he might be able to give the set for atleast 2.6k... Tell him Jade or Nolet sent you... Bring your crankshaft to "Mang Joe" at Exact Racing for press-in/ press-out works on your pin... They'll be able to do a decent allignment and balancing on your crankshaft for a good price without having to spend more as with Precision's...

 

[X Project]

You need not to worry about other possible damage as the maximum damage has already been inflicted on your engine LOL... If you have extra dough, replace your side bearings (crankshaft bearings) with brands at par with the best that you can get a hold of... And dont forget to use genuine overhauling gaskets... But actually it is very necessary since this wont be the 1st time you're opening up your crankcase...

 

[oicat]

crankcase was broken..
if clearance was good why 1 valve only was broken so i think not in good alignment.. well big valves and vixion coming!!!
