I got the BBK installed. Wasn’t that bad and I have never worked on a motorcycle EVER. I got all the items that DHM said you so needed. Just finished, maybe 10 minutes ago, installing the oil cooler. Add 93 octane fuel 10w-40 and started her up and holy moly. Sounded mean. No hiccups. Started right up and just purred. Gave it one rev and my exhaust even sounded better after the BBK and all the recommendations by DHM. Plus the installs were easy to medium. If you watch the videos over and over again like I did, makes the install a breeze. Sorry for the long review. But this bike sounds like the fastest slowest bike in the world. lol.
