has improved drastically but
they still have the easy-to
ride-nature of a 250.
The 350 engine is reliable.
The plain-bearing crankshaft
means that, with regular oil
changes, the crank will
generally last a lifetime. The
valves and engine components
are all good gear, and so is the
clutch. The only issues I have
seen relate to the fact that the
350 doesn’t agree with dust.
The stuff doesn’t damage the
Del West valves but it does burn
around the piston crown and
will stick the compression ring
in its groove, causing a loss of
compression. This results in the
bike becoming hard to start and
eventually it will not start at all.

SUSPENSION
Fixing the damage means a
teardown to clean out the ring
groove. The solution for this is
to clean the air fi lter after each
ride and make sure it is sealed
well.The chassis and suspension
components are all good
quality, although the WP fork
has coped some criticism over
the years. The Xplor 48 is too

soft and lacks compression
damping for racing but can be
fi xed if you are willing to splash
some cash. There are kits
available from RaceTech and
Dal Soggio, which manufacture
replacement inner cartridges
or valving systems that
drastically improves the
performance. KTM has
improved the fork on later
models but the performance
isn’t drastically better and the
newer ones are still a little soft
and spongey for racers.
The only other issue I have
seen with the KTMs is fuel
pumps cracking but these were
fi xed under warranty. If you are
looking at a 350 second hand
then make sure it starts and
runs easily with no rattles.
Check for a service history and
even remove the air fi lter and
make sure it is clean inside the
fi lter, with no traces of dust.
Then check all the bearings and
brakes but pay special attention
to the swingarm and shock
bearings as these tend to wear
out and can be expensive to
replace.
