The 12 ounce weight will give it about the same flywheel as an EXC model.
For the 250 we recommend adding 10 ounces for most intermediate trail riders and less aggressive MX riders. 8 ounces for aggressive trail riders and intermediate MX riders. 12 ounces for casual trail riders or very technical terrain. 6 ounces for aggressive MX riders.
For 360-380 go one size heavier than above.
Fits under the stock ignition cover with out modification, extra gaskets are supplied to move the cover out a little.
