And re ally tricke d It out. • We started with th e e ng ine, adding a resonator box to th e Power Valve system and used a Kelh ln carburetor which gave th e motor a harder hit In th e mid-range portion of the powerband to give you more pulling p ower out of the corners. We cha nged the Intake manifold radius a nd reed va lve system for Imp roved a ir flow. Eve n the alrbox passageway got boosted. so th e YZ250 can take b igger oxygen gulps. And we c hanged the Int erna ls o f the Power Valve for more control and a lo ng e r, wider power hi t. Then we topped It off wit h a stronger Ignition system th at genera tes higher voltage at the spark plug. We even dove Int o th e transmission and figu red out a way to make It shift crisper. • The next stop was handling and suspension. We went Into the Racin g De partme nt and borrowed th eir fork design that features the new mid-range travel va lve. It boo sts the suspension's mid stroke p erformance (where your forks work the hardest). Then we slipped In a larger shock pi ston and ring se t-up .

The fro nt no w ha s new pads for a more positive fe el. while the rear got a new stainless steel rotor a nd a new caliper guard . And since th e wheels were off anyway. we desig ned a new spoke set-up to g ive y o u more time between ma intenance Int erva ls. • The last thing we d id was brighten the color a little b it. Dldn·t make it fa ster-b ut It looks cooler. • Sorry about taking,all that hop-up, t rick-out stuff away from y o u-we just couldn't resist doing It ourselves.• E YZ250 r s livin g larg e In th e high rev ra nge-the 125 c lass-a world of wide open throttle, lots of c lu tching a nd a b illion Shifts p er la p .
