[QUOTE="BkerChuck, post: 1359086, member: 29320"] tempest766, I see from your sig line you're a fellow Buell owner and think perhaps that bike is the reasoning behind some of your questions. Having worked for a HD/Buell dealership those sorts of mods and requests were really common as EPA mandates to make the pushrod V-twins compliant did often have detrimental consequences on performance and engine life. The large displacement inline four cylinders on our FJR and it's kin are completely different animals and while some mods will work and cross the lines of engine families such as freer flowing exhaust the gains are often times not as significant. Good luck with whichever direction you choose to travel [/QUOTE]
