This track is doing my nut in! I must be consistently about 1-2 secs faster than Dark Soldier near the top of the first hill, then it all seems to be a bit random whether i get any further. As i'm new to this game, not sure if i'm doing something wrong or if there's a fair bit of luck involved!
Probably making the same mistake I did on my first few goes. The key to speed on this is, well, minimising the use of the accelerator and pressing/holding right. There's certain sections where the bike will come away slightly, gently lean back into position and the grip should kick in. Never, ever flick the bike on this course whilst heading upwards, it'll screw you right up. Learn the places where you need to quickly ease off the accelerator/holding right, and just practice.
Also, if you're 1-2 secs faster on the first bit, then I dunno how, I can only see about an extra .3/4 to be made there.
