Weird noise?

[K Vee Gee]

Hi.

I have just changed the gearbox oil in my Gas Gas TXT 250 Pro and everything was going well for about 15 minutes, when all of a sudden in third the bike makes a loud banging noise, so I turn the bike off straight away. The gear lever has a lot of movement and all the oil is still in the gearbox.

Does anyone know what has happened?

Many thanks.

when i had my trials.. i learned a ton on this site..

there is a shifting problem link on it, but the noise you are talking about does not sound good..
