200:1
For you tuner types reading this, I’d like to point out something for you to think about. Our MICROBLUE coated YZ250 engine requires a 210 main jet to run properly! The standard main jet used in a YZ250 is a 178!
In my mind there can only be one explanation for this change in jet size, this motor is pumping more air than a standard YZ250 two-stroke.
An interesting benefit is the sound coming out of this motor. It just does not sound like a typical YZ250. It has a deeper, more throaty bark. Another important point is the power delivery, which is very usable, with a tremendous mid-range that screams out into an amazing top-end. This is one very powerful machine
Shit, this stuff even ports your jug for you.....

they need to try that with 40:1
or i bet it didnt start out as a "standard" YZ250
ill believe it when i see itthis motor is pumping more air than a standard YZ250 two-stroke.

the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.
