Hi 2Sharp
Regarding engine starting, it's rare that the engine catches immediately after starter operates, particularly if engine cold. I would regard your comment on such as normal as well therefore.
Make sure fuel pump has finished before pressing start button though, and during cold winter starts, cycle pump two or three times by switching ignition on/off before starting.
ETA: echo Sportster's comments - I also recommend Iridium plugs which fire at lower voltage.
Note also (minor) starting issues were the same before and after fitting Stage 1.
