Is anyone else having a problem with their handle bars rubbing the plastics when turning hard? Mine are and only after 15 hours is looking rough. Looks like it may rub holes after a couple years. I saw under the seat that there is 2 plastic retainers, that allows the plastic to slide forward. I was thinking about pulling back as far as I can, and putting a couple of bolts in it to hold it back. But, worried it may end up tearing the holes b/c it wouldnt have any play in it. Already tried adjusting handlebar.
