Went to install a new crank in the viper and when the tolerances were checked one lobe measured from .001 to .0015 with plastic gage. This indicates there is a slight taper? Should I be concerned? All the other measurements were .0015

.0005 is a lot of taper in that short of a distance, but I'm not sure I'd trust plasti-gage for an accurate measurement.

I would have it checked by a reputable machine shop. Plasti-gage can be fairly accurate but .0005 is quite a tight measurement.

Hey at this point, why wouldn't you have it look at?
