Well i finally got the bearings done and for the record I needed GS 1000 bearings. before I refit the arm I may get the polish out

Ah thanks bud, thats probably where Ive gone wrong then as I measured the i/d across the face of the rollers ( not that they roll any more as rusted up solid) the arm is stamped gs750 gs1000 gsx750. Thanks for the offer but am popping into my local shop tomorrow they keep a selection of bearings in stock.

Youre right my bad, just checked again... 33 o/s 23 i/s 30 d

Got the arm out, bearing size is 33 o/s 29 i/s 30 d so not standard size? Guessing I measure inside between the rollers right? Or is it casing size? Standard size is 22x29x30

Yep tis definatley Metmachex, I removed the sticker when I first got it. I'm going to remove it today and see whats there, keep ya posted

Hi guys, new member here, I have a 78 750 fitted with a Metmachex arm. I need to replace the bearings and wondering if my arm takes the same bearings as a standard arm. Just wondering what I need to order before I take it apart. Thanks
