You've nothing to lose by having a go at straightening your old needle. The absolute straightness is critical up near the needle's shoulder; as it tapers the straightness is less of an issue unless yours is like a donkey's hind leg causing it to bind in the jet. You can centre the jet using any .090" SU needle - as well as being used in 1 1/8" carbs, these were fitted to all 1 1/4" SUs and some 1 1/2" models.
