Just been dissasembling my son's GSXR250 and the rear engine bolt had me buffaloed, no matter which open ender I used it would fit once but not the second turn?
It wasn't until I got the damn thing out that I realised that Suzuki had machined the face off of one side, this is to allow it to pass so close to the frame upon removal that a standard bolt head would jam.
Weird huh!
