Hey guys, im wondering why it is when you buy a bike from new and get the stage 4 kit fitted, that the street kit is covered by warranty (if done from new) but the stage 4 race kit is not covered by warranty when the only difference between the two kits is stronger valve springs, bigger injectors and tuner included in the race kit. I have asked a few people and have been told it's due to emissions and also due to Harley having no control over the tune but I can't seem to get a real answer, does anyone have any info? I know heaps of blokes who run tuners and still have warranty??
