I was wondering whether all 914's inherently are unable to shift from 1st to second without quickly--a slight hesitation has been my experience.

The bushing had been replaced, the shifter is a J West rennshift,tranny was rebuilt by Dr Evil, and it shifts fine from 2 to 3, and 4 to 5. Three to four takes a little work, but a lot less than 1 to 2

Any experience or suggestions here ? (IMG:style_emoticons/default/smile.gif)

There is too much info here to clarify categorically, so I will just say that:

1) If it feels like friction going into a gear, it is in NO WAY bad teeth. Bad teeth GRIND. Friction is due to the synchro band, lube, slider. External things that change and can cause this are shifter bushings and improper clutch adjustment (drag from too tight).

2) The factory recommended changing oil every 10Kmi or yearly, so he is not crazy. The oil to use is 80w90 GL5 cheap dino. The more expensive the oil, the worse it will perform. Unless it is swepco, then it will perform well while it is polishing up all of your insides (not good) (IMG:style_emoticons/default/smile.gif)

3) 2nd is, by design, often a bitch to get into. But, this does not mean that it has to be. If this is a new thing, then start with bushings (you did this) and check the cable. The Rennshifter is either dead on, or it is off. There is no middle ground as it amplifies any imperfection. With a short shift you may be happier (IMG:style_emoticons/default/smile.gif)
