Thread: How long do heads last?

    Default How long do heads last?

    Serious question,

    Providing you use good quality oil at a 25:1 or 28:1 ratio, run a good tune and use a good air filter how long will the head last before it's plating is considered 'no good'?

    ive had an OBR 29.5 fm get 86 hrs before the head cracked and still plenty of life left on the head, to many things can fk them up early.

    Not really a very good question to ask because not many keep an accurate reeding of engine hrs

    My standard zenoah g290rc has more than 30 hours but there is no signs of wear. A local racer has a g290rc aswell he used it for more than 130 hours and the engine is still going hard without issues.
