THE BOTTOM LINE
spokes and nipples. Since this was an off-road build,
Colin and the crew built us an 18-inch rear wheel for
some extra flat protection, and we mounted a set of Pirelli
Scorpion tires to tackle the elements.
At the beginning of every project bike build there is
always a plan, but you have to expect a few surprises
along the way. This project had surprises around every
corner. The first thing we noticed was how much power
and throttle response the YZ250 gained with no major
engine modifications, just the addition of a VForce3 reed
valve, FMF Fatty pipe, Turbine Core 2 silencer, VP T2
race fuel and a little dialing in the jetting department.
Another thing we are reminded of every time we build
a two-stroke is the amount of testing time it takes to
dial every aspect of the machine in perfectly. It’s a lot
of hours, and very rarely do the same settings work
for multiple test riders. So far we are pleased with the
overall performance of our YZ250 off-road build. It
has more usable power than in stock trim. It has
a plusher feel suspension-wise, and it has all the
bolt-on necessities to take us far away from civi-
lization with a means to return safely. These are
the things that make us here at Dirt Bike very
happy. Don’t be surprised if you see this bike
in the magazine and on www.dirtbikemagazine.
