Honda XR 400R SPECIFICATIONS, PRICE & IMAGES
The air filter: Check the air filter, and if you don’t mind getting your hands
dirty, feel around to the other “out of sight” side to make sure it’s seated
properly. They can be fiddly to replace and if it hasn’t been with care, dust
may have entered the engine through the gap where the filter has failed to seal
with the airbox.
Muffling and jetting: A secondhand bike should have been de-restricted but may
not have been. If the engine hasn’t been derestricted, do it yourself when you
get bike machine home. It’s easy. Remove the airbox lid and the muffler end-cap
(both of which are immediately obvious) and the restrictor in the inlet
manifold. Replace the standard main jet with a 158 jet.
Gearing: Standard gearing is 15/40 but going to a 48-tooth on the rear
makes a big performance improvement. It’s easy to check the number of teeth,
even for the numerically impaired; the number is nearly always stamped on the
rear sprocket.
Steering head: Sometimes you’ll find a grease stain on the front mudguard under
the steering head. This caused by grease from the steering melting on a hot day
and dripping onto the guard. Check the steering head for excessive looseness or
notchy movement. High temperature grease is the thing to use. Packing the
bearings is not a hard job but can be a bit messy.
Aftermarket goodies: Many like to personalise their bikes and there are still
plenty of aftermarket cosmetic and performance goodies available for the XR. The
only limit is price, how much can you afford to spend? Bark Busters are the
first thing to put on any bike in my opinion. They save a lot of grief and
injury in tight trees and silly falls.
Bars: Standard handlebars can be a bit low for the taller among us. If this is
the case for you, a cheap fix is to buy two more top clamps and four longer
bolts. You place the new clamps upside-down under the bars and put the originals
back on top with the longer bolts.
Blinkers: Standard blinkers are large and damage prone but can be replaced with
clearance lights available for a song from Repco.
Rear guard extender: The rear mudguard extension is the first thing many owners
remove but if it’s still in place, move the numberplate higher and then trim the
excess plastic from below it. This shortens the extender to a more sensible size
and still keeps the bike street legal and the coppers off your back.
Plastic chain guard: The plastic chain guard above the swingarm is an
absolute joke. Remove and toss it if it hasn’t already been torn off from trail
use. A bashplate is a good investment, especially if you get serious about your
tail riding, Whipps Alloy Products (02 6585 0944) do a plate for the XRs that’s
easy to fit and great protection.
