Worn valve springs. It means the springs lost ther tennion and you drop a valve.A very expensive fix . Lucky I got the know how to do engine rebuilds

You cannot teach me nothing cause you know absolutely nothing.

Only way to know if you have done it wrong is to open it and pray nothing is bend.Hopefully you get lucky.Make very shore your flywheel index marks are lining up with your camshaft

Also check your valve clearance with a feeler gauge. Ther are maney other vids on hoe to adjust your feeler gauge gaps

@@deliverance3767 Thank you very much ❤️

Look up your make and model and see if ther is a aftermarket kit ' barrel and piston with rings to fit your make and model.Make shore to also replace top end and bottom end gasket

Thanks ✌️

You have never ever workted on a motorcycle. I can tell you that you do not know what you are talking about cause you are as dumb as a plank

Thanks! 😃

Could be

Valve springs were worn after 54000.00 km.The valve spring lost its tennion and could not open and close on the correct timing.It destroyed the piston and the head.Before it blow up it was not running correctly for about 2 months.I could not figure it out untill it finally gave in

Bought a usted head and bought brand new piston and brand new piston rings'botton end gasket and top head gasket.The 4× domme nuts and 4×copper washers.4×retaining head studs and 4×flange nuts.Also bought brand new valve springs for the exhaust and for the intake valve.Both valve have also being replaced as new and valve seals and other bolts for the camshaft 2× gear sprocket and 2× bolts for the exhaust header pipe.Sleeve pin and the 2× circlips for the piston have also being bought.All this at 400-hundred U.S.dollers.This is not as cheap as most will think

I have also replaced the the clutch basket assembly 'the friction plates and the steel plates and the the clutch basket springs which cost another 50-dollers in parts before it blow up.Now I be ready to assemble it all in one go

@@deliverance3767same just happened on my ktm duke 690 20,000km

Just don't ever use yout torque wrentch as a breaker bar.I use a blow torch and a ratchet to break bolts and nuts loose.A torque wrentch must only be usted for tighten.

The top ring is the lighter color and the bottom ring is the black ring

Thanks man
