[QUOTE="user 89595, post: 1375581, member: 89595"] 07 model. I had 2 brothers exhaust on the bike and did not like them (Don;t like the rumble). I put OEM exhaust back on this weekend. When I performed the throttle body sync, I noticed something I have not seen before. All 4 cylinders are even on the scale. If I bump the throttle, they all come back to the same level. But if I run the throttle up to about 3000 RPM and release the grip, No. 3 returns much slower than the others. They will settle out even after about 2 seconds. But the initial return is much slower on No. 3. The bike runs fine. I love the sound now. Runs very smoothly. Has anyone seen this before? [/QUOTE]
