Yes I actually called and spoke to a supervisor and got her name. As long as it is a CARB, EPA compliant with certificate they cannot and will not void the warranty. She also went as far to say it applies to the entire bike as I explained to her all of the hear say between the dealers, consumers and the mothership about the warranties being voided. She told me that any and all aftermarket parts will have to be proven to cause the failure before anything will be voided period. She Stood behind her statement after me cross examining her at several different angles that all led me back to her original statement. Now that doesn’t mean that they won’t be examining every major aspect that they could blame you for to lay the blame on you. They are very slick smooth talking weasels. But they do have boundaries that they need to follow as well or they will not sell many bikes in the future at a time that sales have plummeted and no bright future in sight. So the mothership will need to walk a very thin line the next few years with the warranty issues so unclear, something could very well sink the vessel.
