Elka fully
adjustable Rear Shock
|
The stock swing arm was retained, but we replaced
the stock shock with an Elka full adjustable rear
shock. The no link design used on the Raptor was
fairly decent in stock form, but now will really
shine as rough terrain is tackled at speed. Also
in the rear of the Raptor, we borrowed another
part from the Raptor’s big brother, a LSR
Sprocket guard for a YFZ450 bolted directly on
and should offer us protection and ground clearance,
both of which are in high demand on such a small
machine. An adjustable Lonestar chrome axle rounded
out the rear end and offers us adjustability and
added strength over the stock unit and also includes
LSR's warranty, which is a good thing seeing we
will be bouncing this machine off trees that tend
to try and rip the axle off the machine.

Pro Taper CR double-high handlebars will be utilized
along with their new grips. An MSR adjustable
clutch perch and lever replaces the factory unit
and a Pro Design kill switch keeps us legal for
GNCC competition. To round out the list of parts,
a set of Streamline stainless brake lines replaced
the factory lines for even more improved braking
up front. A set of Lonestar racing brake line
clamps keeps everything secure. The Maxxis Razr
tires, front and rear, will remain mounted on
ITP Baja rims to conquer whatever we may face
as the season gets underway. Future plans are
to add a Lonestar anti-vibe steering stem and
a bar mount style steering damper for increased
rider control. These items are being built and
were unable to be included in this article.
The machine will now under go normal break
in runs to assure we have everything race ready
and to check things like jetting. GYTR jetting
was used during this build and from our first
test ride seems to be pretty close for our elevation.
We are now ready to hit the race track with
the start of the GNCC race season, and really
see if all these performance products perform
as well as expected and how well the Yamaha
Raptor 250 holds up through a race season.
