hey ATV/qaud guys...need some advice

Have bought a couple Chinese atv's for my son. Honda knock off engines like the old 50 and 110cc engines. Good experiences with both. He rode them both about a million miles. First one was a three speed like the old Z50. Honestly I don't know how it survived. At first he couldn't shift it so he just zoomed around in first gear reving it about 10k. Got him one like this (2nd one) when he was 9. He loved it. They both had remote kill switches and throttle goveners.
