.....I'm so sorry for the delay, I had a car accident.
I hope you are OK and that the damage will not cost you too much to repair, or is fully insured.
...I was always touching the cylinder head in order to check the temperature and at this moment it was a little bit hot.
This is an ABC engine!
It must not be cold enough to touch, even during break-in, as illustrated in the thread I linked in a previous post.
Only cast iron piston, steel sleeve engines and ringed engines must be warm and touchable,
only in the beginning of the break-in.
To be honest I can't believe that the MVVS quality is so bad, of course it's not your fault but I want to show you what had happened and what do you think about this issue.
Attach you'll find some pictures of the broken parts.
I cannot believe this either.
This damage is quite extensive.
I have never seen any such damage in any MVVS engine; not even in very old ones.
I may have more to say later about this.
I wanted to replace everything; I'd have to buy the cylinder head, cylinder, piston and connecting rod but you could imagine that if I buy all these spare parts could be exactly the same price if I buy a new engine in my country. Do you know if I can use a different connecting rod from another engine, I don't know; Super Tigre, Webra, etc.? I tried one from an OS .46FX it fits perfectly with the piston but the lower hole is too big so, I can't use it.
As you know I bought this engine on march 2002 do you think I could get some warranty from the manufacturer, this is a quality problem with this engine, if so, do you know what is the procedure?
As for parts cost, please E-mail me.
Parts are much less expensive than you may think.
American market prices and prices in your country, do not apply elsewhere in the world.
