[b]Mods to my bike for the woods[/b]

I have a 94 YZ 250, that is mainly ridden/raced in the woods. Here is a list of mods that have been done to make it rideable in the woods.

Cyl. Head = Squish band re-shaped (EGORR) to smooth out the "HIT". (also allows the use of "pump" premium)
Cylinder = Stock porting/Std. bore
Flywheel Weight = 11oz. Steahly (bolt on) to make the power delivery more "tractable" (lessen's the wheelspin off bottom)
Carb(MIKUNI/TM38SS) = 6EJ33-59 jet needle,#380 main, stock pilot (as per EGORR)
Reeds = Boyesen pro series (EGORR)
Pipe/Silencer = FMF FATTY/FMF Power Core II
Final gearing = 13/51
I run a premix ratio of 50:1 (Amoco93/Motul 600), and a B7ES(MXTUNER) plug. Even with these modifications, the bike is extremely fast on top. It now  has better manners down low and through the midrange

I realize that you have a 95 WR 250. There are many similarities between the two bikes. So I thought that this info would be usefull.
