Once you get your gearing sorted, look at fitting an old street tire to your rim for the traction, or if you have a worn down knobbie, you might be able to warm that up on some bitumen with the front wheel against a wall or fence... then get out and launch that sucker... you will probably have to slip the clutch to get the drive without the front wheel too much of a bother... though a rolling start would eliminate that to a degree...

I think your experience on bikes may be the winning edge... :thumbsup:

Hey man thanks for the support and advise.

But traction is not the problem.. well actully it is . I'm getting too much traction. I tested taking off in 2nd and in 3rd and still I can't keep the front end down. Im sitting all over the top of the gas tank but it still picks up the front every time. And not just a little bit, I mean it stands straight up if I don't stop it. Go to the general forum and look for the subject "Drag Race YZ450 vs. FZ6" and read my last post for my theroy of the only way I can win this race. :thumbsup:

Thanks clown! Just kidding :devil:

With a street tire, you will be able to slip it and what situation is better... a rear tire slipping because of the power, or one that is going slower than the engine can drive it...

once you slip that clutch and let that tire heat up, it is going to be hard to get you because of the gearbox ratios on the dirtbike... at least for the first 200yards anyway...

I would say practice your starts in 2nd and 3rd...practice smooth clutch release as its key to a good start on asphalt, and sit way forward to help keep the front end down. My 426 spanks my friends CBR 900 for less than an 1/8th of a mile with 15/47 gearing(good for about 92 MPH or so), then he would go screaming by. :devil:

My R1 will spank my 426 like it is still in neutral every time.
If you race a squid you may win because he stalls it, but if he gets into 2nd gear- you are done.
I will pull lengths in the 1st 60ft let alone 1/8th mile.
You may be able to beat a shadow 600, but why? :thumbsup:

If wheelying is your problem, move your forks up in the clamps as high as they'll go, buy a works connection E-Z holeshot, or just strap your front end down. Moving the forks up and strapping the front end will help while going through gears, the holeshot will help the start only. See if you can find a good dual sport tire for the rear, or even a Maxxis flat tracker (depending on how much $$$ you want to spend to win). In a 1/8 mile, I think you'll be beter off with the 48 tooth rear, because the 40 will make it run a little more sluggish.
