rear sprockets (and also catseyes)

[Keen]

I've been told that to fully derestrict my Cagiva Planet I need to fit a new rear sprocket with 39 teeth (the smallest that will fit) but I don't want to loose acceleration. The mito has 38 teeth- does anyone know the 0-60 time of this bike? how do you think this would compare to my bike which has a mito engine but 43 teeth standard?

On a different note, do catseyes affect the bike's stability? I was thinking that you'll have to ride along the white line when overtaking, but I wondered whether you'd have to avoid cateyes or not?

Well obviously it does not help going over cateyes in the road, but I have overtaken many cars and gone over cateyes no problem, but like I say try and avoid them if possible.
