square taper bb, help!

Hi i bought a stork crank and a titanium bb square taper, the problem is that the taper only goes half way in the cranks. someone told me i must get a ISO square taper instaed of JIS, when i bolt it on it seems still very stiff but the chainline will have to be adjusted, for single speed use, is it safe? or should i look for another bb?

You'll have better contact on the BB facets if you go with the smaller ISO taper. The likelihood of wrecking your cranks will be lower.
Current setup is not what I'd call dangerous, though.

That is a good idea.

Since you're here...

If you tighten down the cranks you are not in great danger, in my experience, of damaging your crank but getting the right taper would be far and away the best move.

If you bought them together send the BB back and tell them you need the right taper.
