I like narrowed tanks and I say do it, but you might want to skinny up anything else you can, like that license plate bracket. As far as which way to do it, I vote for evenly.I'm thinking of narrowing this tank but doing 1.5" at the bottom and .5" at the top. What do you guys think? Leave it,narrow it evenly or do the 1.5" to .5" taper?
