a tire that hooks up.
if you are going sideways ,you're spinning.

I agree with Jim...Try either less launch RPM, or maybe less air in the rear tire.

I just put a shinko stealth on my dyna . I was having allot of trouble keeping my tire from spinning once i got past the prep . Definitely try dropping your pressure . Ive had mine as low as 20 lbs .

Before I ran the stealth D . I had to run 13-16 lb on my Shinko 777 and elite 3 . It still wasn't enough traction on most tracks for my setup .. When I went to the skinko stealth D I can run 20 lb and up . The more air I can run the better the MPH . Between 20-26 is the sweet spot for the stealth . At least on my setup .

This was the old Shinko 777 with 13 psi . Bowling Green track prep is top notch for bikes though.

That ^^^ Looks like a perfect contact patch...and a Very controllable Amount of Wheel lift...good weight transfer and Probably a Damn good 60'...if it didn't get alot Higher!!!
Hell...Look at "P" back there...he is Spellbound!!!

It was a decent 60 ft . 1.70's . That was the highest point of front end lift . (Thanks Motolenz)
The problem with the tire pressure in this launch ( shinko 777) is ,I had to run such low psi to get it to 60 ft ,it had a slight wobble on the big end .
With the stealth D , I can run more psi , get a decent 60 ft , pick up MPH and have no wobble on the big end .
Jimmy P is the best . I really like the way he takes charge of the staging lanes .
If he is there, we don't have those E class Goons hot lapping back to the lanes and keeping the pro tree lanes from getting more than one T&T shot , before qualifying and elimination rounds .
Give Jimmy respect and he gives you back more . :beer:
