Thanks lee. It can get under 40xx if you do the goomba thing. I'm too lazy to do it though http://bike.toyspring .com/game.php?g=87612 its when you get your wheel stuck under the second goomba.
Yeah - I'm not convinced about the Goomba kick you are looking at - I recon you can flow over it without slowing down at all.
The big slow down points are rolling over the "flame", hopping over the third goomba with good flow to get up the ramp and the bounce to get over the last goomba with flow to keep rolling up the last ramp.
I let my sister use my 650 and she started playing some levels from a random pack (not hall of fame) and she beat some times and changed the username so when i got that time i didnt even look at the name and just pressed ok
