SLEEK SPROCKETS
As the old adage goes – ‘if it isn’t broken,
don’t fix it’ and with Warren that
means he sticks with what has worked
for him over the years – he’s become a
creature of habit. So he defaults to the
same suppliers every time. In the case of sprockets
suppliers that means US manufacturer Dirt
Tricks and their super-lightweight Zirconium SE
chromatic rear sprocket, in this case a 46-tooth
rear, matched to a stock 14T countershaft
sprocket. Let it be said this wasn’t ideal gearing
but was a case of force majeure as we found we
had run out of stock (in the RUST workshop) of
our Dirt Tricks 13T sprockets. This set-up came
back to haunt Warren at the Trefle Lozerien,
where it felt too long, so the answer would be say
a 14/48 or 13/48 for real snap!
LINKED-IN
Our first choice in chains is
always the Regina’s Z link chain.
Its seal rings have a unique
conical shape on their inner side
that helps trap lubricant and
improves durability and seal. These chains are
super long lasting and more importantly we’ve
have never had a chain issue since we started
using them. A quick tip is to always mount the
master link clip on the inside of the chain to
reduce the risk of the clip inadvertently getting
prised off in a ‘lay down’.
SMALL BATTERY
Just as KTM have done with
their latest models, we replaced
the stock battery with a new JMT
Lithium Ion type that is almost
a full kilogram lighter and offers
superior performance in both
hot and cold weather. It’s worked flawlessly since
we fitted it and it’s available from KTM Power
parts.
BETTER SPARK
We replaced the stock spark
plug with high performance
iridium-type, an NGK
BR9EIX. Warren typically
swaps between the 9EIX for fast
high-speed stuff and the 8EIX
for trail riding, given that the 9EIX can be a little
cold for slow speed riding. In any event we’ve
never had a fouling problem with either of the
plugs, they’re long lasting, stable and for a few
bucks a year more than the stock plug a worthwhile
upgrade, especially if like us you choose to
run the Lectron carb and K&N air filter combo
with a higher air/fuel mix ratio.
