Bad metallic rattle and no 1st gear?
 

Hi everyone, I've just bought an MZ Baghira with a Yam 660 engine because it was too cheap not to! I know it's not an XT, which my budget couldn't stretch too at the moment. Anyway it's got a really bad constant metallic rattle and there appears to be no 1st gear. Could anyone point me in the right direction? Can anyone also tell me where I can get a copy of the engine manual that covers the 660 please. Any help would be gratefully received!

Cheers Mud
