Never having ridden an eastern hare scrambles I can't say for sure but I know that stock tank is only good for about hour and a half WESTERN hare scrambles, or about 50/60 miles. So I would guess you'll have to pit, but it will be close.
My last race time was just over two hours for about 65/70 miles and I estimate I burned almost 2.5 gal.s (I have 426 w/ IMS tank). The course did have several long, high-speed sand washes (I'm sure these use more gas) but was obviously not super fast overall (~34 mph).
My IMS tank fits perfectly. I picked IMS over Acerbis after seeing a YZ400 owner who endured some mounting difficulties w/ Acerbis (side panels and seat).
Hope this helps...

100km or 50miles+.
Or you may want to install a milage meter
and plan out your pit stop for gas.

Go to the members page and look up Jeff Shearin. He's a buddy of mine and has ridden a bunch of Hare Scrambles and GNCC's in the southeast. He has a YZF and I do know he pits on two hour races. But I'm not sure if that's a "just in case" or can the bike go the distance?

I race GNCC, va. and NC. Harescrambles and I can get 4 laps(35-50 miles depends on lap lenght)on one tank.
I try to pit just after the finish line so I will know if there will be a 5th or 6th lap before I stop for gas.
It's not much info but I hope it helps.
Let me know where your race and ride mabey we can get together and roost.

Forgot to mention the reserve capacty of the yz tank, ZERO, NADA, ZILCH. If this is important I would use the wr valve if possible. This would limit the non-reserve ride time due to the height of the primary tube. IE: you would have to hit reserve sooner than if you had the wr tank.
