yea ....I can't master the boost at the start either -_- never been able to do it in MK:wii yet .....when do you press or hold A ?

heres some tips

1. use bikes.. they're easier.. and have the wheelie which gives u a 4 second boost, which will help u

2. Boost @ the start, HOLD A when the 2 light stops ringin...

3. Play the Ghosts in Time Trial... and master the tracks

4. Do Tricks on ramps whenever u can, give u boost

5. Do a boost everytime u turn 

Oddly enough I am doing better with karts than bikes so far. I haven't started the final push to 3 stars, but for lesser feats it has been easier on me occasionally. Don't really know what to make of that.

Yea I prefer bikes > to Karts also the wheelie alone is a win win for me .....I was 2sec from finish line neck and neck with 2ppl I pulled a wheelie got pass them :) to steal 1st place.

Ok so I hold down A right after the 2nd light is gone to get a boost at the start ?

Ahh, I was wondering what they changed the boost to. I liked timing the Go like he previous versions...

Btw, what is the trick button if you use a gamecube controller? I suppose I could try it, but I don't see an advantage in this game for anything other than Wiimote+nunchuck. However, if I want 3 players I'll need to use my GC controller.

you mean do tricks while jumping off a ramp, you press the D Pad while your in the air, up down left right whichever one

we need to get a team of Vgchartz people and go into battle mode as a team if thats possible and cause chaos !

ugh, is there a way You can manage to escape a pow block

yea pop a wheelie or do tricks on ramp to avoid pow blocks ....
