Some advice and guidance please. (Please take in to account I am in the UK (England)). 2010 FLHTK 1690cc. I want to fit a stage one setup onto it. 1). Is this something I can do myself? 2). What fuel upgrade is most suited? (I would prefer to save money where possible, by not buying the most sophisticated when it is not required). 3). I want to use Vance and Hines Ovals or does anyone recommend anything else. After looking for the ovals it appears that the ones I have had on previous FLHTCU's are not suitable for this FLHTK, does anyone know why or is it just a means of increasing the price. 4) What happens to the butterfly valve in the exhaust, how do I lock it in the open position or get rid of it? Any advice would be appreciated but please bear in mind where I live, obscure stuff may not be readily available. Thanks' John T.
