Hi,

It is manufacture fault. In the end I did cut thread myself in the frame. I have bought it from Yamabits for 110, everywhere else have it for 130 pounds. I think it was misunderstanding from their end as I was complaining about missing thread and they replace all screws but left original faulty frame. I�m sure they would change it eventually but I don�t have time to wait another 2 weeks for another replacement so I fixed it myself.

Thanks
