Hello all. Have been considering doing a big bore kit on my 08egc. How big can you go before a bottom end upgrade is needed? Reason i ask is because i was talking to a guy who has a 09ugc and claims to have gone from stock 96 to a now 106,with no bottom end change. So what is the real story as every body else ive talked to says anything over 103 requires a bottom end upgrade as well. Addtionally he had rinehart true duals on this ugc and when fired up up it sounded like a drag car it was so loud at idle,i coulndnt even imagine riding down the road it was so loud. Thanks for any info and have a great ride!!
