Found this quote from Stairliftman earlier in the year.
"Word of Warning to those that are running cans/systems without a remap, the fuelling is so lean lowdown as standard that if you fit an aftermarket can/system without a remap you are risking doing some serious damage to your pistons/valves due to detonation,especially if you are running on supermarket fuel/ high ethanol content

These bikes need to be run on super unleaded to get the best from them."
Having read several latter post, all mentioning that re-mapping isn't necessary with just a slip on can, I'm rather concerned.

Any update on this??
