		My speedo is out a similar amount and I seem to remember my last Fazer was the same. I allow 10% at lower end and slightly more on top end - I would happily ride by a police car at an indicated 85 knowing this is mid 70s max. afaik all speedos are set to under read unless calibrated for plod work
