I installed a Vance and Hines VO2 air cleaner to my 2012 SG. I accidentally installed the original breather bolts back into the heads before I realized that the kit came with shorter bolts. I did not start the bike with the bolts in, I simply removed the OEM bolts and installed the VH shorter ones. Is there any damage that I may have caused, and if so what should I be looking for?? Thanks
