Guys, sounds dumb but i seem to have mis placed my crank pulley. A friend of mine may have one off a B16. I looked these up and they do have different part numbers, but places like UR, and CTR say fits any B-series. So i thought they'd be the same? Would this B16 pulley work on my B18?

Thanks..

 

All b series crank r unterchangeable between each other. The difference is the size of the diameter of the crank.

 

will i be ok running it?
