I am not an expert by any means, but it will depend on whether you retain the stock turn signals and where they end up with the fender eliminator in place. I believe there is a statement on the Yoshimura web site about whether you can mount the side cases with their eliminator.. I don't think the Motodynamic eliminator with the stock turn signals will allow the side cases, but I think you can use some small aftermarket ones that will allow the side cases. Or, you can eliminate the turn signals with the Motodynamic combo light that has the stop light and signals in the tail light unit.
Remember that this is my opinion.
