Gears or reeds?

A v-force helped me out in that area. I was having a problem with acceleration before a jump. The vforce made noticeable improvement. I also experimented with gearing. I would Definately stay with 13 as 12 is just too low and requires a lot more shifting. I am comfortable now at 48. 49 and 50 just made the gears closer but once again I had to shift earlier. If you always go to the same mx track you could just plan a day of sprocket testing.
I have an icat fitted and for my bike it did quite a bit. Very easy to loft front end and revs quicker off idle. My bike is more modified than yours so the difference my not be as noticeable. Maybe someone will let you borrow one to try it since it just screws on to your spark cable.

Ted do you want my mailing address?

IMHO for what that is worth, 12 is not too low on the front sprocket, lets me use 2nd and 3rd in the steep stuff where before I had to use 1st

Most people change their reeds to a VFII when their reeds are old so they notice a huge gain in throttle response. If your bike is in good tune, changing reeds will have an effect, but it will be marginal.

For what you are looking for I'd suggest trying some different sprockets. I'm running a 13/50 combo on my KDX and second gear is great for the slow turns. But Ted is correct, you should try a few differenct combos and decide what you like best. BTW, a 12/47 is the same as a 13/51.
