Now i hope for better cause have maximized the compression for 98octan fuel with octance booster. Ported better, 2mm bigger carbourator and digital ignition :D RPM kick from 8k ->16k (with old duration 140/208, stock ignition(with modified spark moment, 24mm carb)

Nice :D

2 strokes are awesome :D I dont have any cross bike myself but i love the 2-stroke engine :P

Getting much HP in a 250 2 stroke is np, but getting godly hp on a cross rpm band is harder..

Myself i just like the porting etc, working on a old suzuki ts50x. Theese bikes got 2,5HP original, 5-7HP with tune setup(toppspeed around 90km/h). My ported one went 135km/h with a little wrong carbourator settings(to lean mix).

Sleetdawg, You were amazing at Powder Mountain with MC

Having ridden the old CR500s, that generation of big-bore 2 strokes were beasts, and were hard to ride not just because of the power, but because they were heavy, had primitive suspension, and drum breaks.

I've had every brand and size of bike. I just sold my 4 strokes and got a 2011 250SX, and it is amazing! Great power, but easier to ride than you would think. Better turning and handling than any 450 I've had.

@MxQuestion572 It's in the current print edition of MXA, it's not on the web yet. Those are Pro Circuit's claim.

A flywheel weight would calm down the delivery for you 4T riders.
