Hi mate .. ive had mine for a month so far.. Added radius freedom pipes, Hid the front and rear indicators with LED's and Maximus Tuner. Love it
I would definitely check if they will keep the warranty with the 475 cam which is probably a S&S one(if they do that's good), I have a 117 Lowrider S(same engine) I did 5000k's with the stock engine (apart from exhaust and stage 1 tune still with warranty) I then went aftermarket(not much warranty now) though Fuelmoto USA and sourced a Woods 22xe cam with upgraded lifters(stock ones rubbish),inner cam bearing(stock one shit) and adjustable pushrods with gaskets which came in a kit, with the 117's you should also go to larger injectors I went with SE 5.5gm/s ones(stock 4.38gm/s), The SE cams are fairly tame really I had the se462 in my previous 114 LRS and lost a little power down low but gained more higher up the rev range(approx. 4000rpm) If I did a se cam again I would do the se447 torque cam more power where you want it for general road riding/cruising, I have included some dyno runs via Fuelmoto - https://university.fuelmotousa.com/dyno-charts/
I had a similar chat with my dealer, but was the other side of the equation.
