I have an 03 viper that I made an ER and an 04 ER from the factory (black). BOTH SLEDS ate the snowflaps while I was driving in REVERSE!!!! I went to Yamaha and bought another snowflap and the ER ate that one too... is there the WRONG snowflap OR do I have to cut it in HALF to eliminate the track studs catching and eating ANOTHER FLAP?????
