I just got a set of r&g crash protectors for my 2000 929 blade. Foillowing instructions i undid the nearside engine bolt and put the spacer in the recess in the frame. After a while of trying to fasten the bolt, it seems that it will not work and the bolt is spinning, but I'm no longer able to tighten or loosen the bolt - it's just spinning round with nothing happening. There is about 10mm of play where the protector is moving inwards and outwards. Has anyone else experienced problems fitting these? and if so, how did you go about sorting it out? Cheers, Charlie.
