Lifan LF250GY-2 - Need new Gearbox

[Rockhorn]

Here is a picture of the gear, you can see how much unused it is, the teeth are barely broken in, yet a WHOLE piece broke off from it (you can see it in the right side) and went into the other gears:

Obviously the metal was not built up to the required tolerances for 20kW spinning power. I was very happy with my bike but I do not understand how the Chinese wish to compete with the Japanese while making porcelain parts for the gearbox...

You might try Hamachi

That was one my first tries, they don't have any parts for that engine :(

Usually with the expense of fixing a motorcycle gearbox due to the complexity and therefore the time consuming nature of the work, in most countries given the cost of labor it is easier and cheaper to unfortunately change the entire engine.

Try to get Lifan to warranty the engine, or go with a 2nd hand engine from whomever Lifan cloned the original from. Honda, Suzuki or Yamaha most likely.

I believe the warranty period is over.

Luckily, they finally did message me through Facebook! Email didn't work, but yeah Lifan responds via FB.

The bad part is they want around $140 in total for a complete gearbox and express DHL shipping. This is all good and I would receive the parts in just a few days. Will decide on Monday what to do once I can contact the mechanic again.

The labor is cheap here and I'll get it done for $70-$80. The problem is only replacement parts.
