I started with a $150 1976 550K, drag pipes, high bars, pods etc. Took me 4 years... maybe a few hours a month. Today was the first of many to come. I rode for 30 min as a shake down. The stock air box with a short exhaust pipe...if I change carb needles will it improve performance? Upgrades include: 550F tank, Hotwings seat, Carpy 4-1, fresh top-end, Dyna S ignition, DOHC coils. I have some $ in it but its way cooler than my brothers $16,000 1964 Galaxie convertible and a lot more fun to ride. I have a problem with the starter and/or button which means I kick start for now. Thanks to all the 'experts" and others for help with tricks, tips, and stuff. I have another one, a 550F that I will begin soon.
