Off Season Bike Maintenance

Joe put together a list of things that we keep in mind with our bikes going into the off season and I thought I would share it with everyone.

CHASSIS - the most neglected part of our machines but don't underestimate how good a properly lubed and torqued chassis can feel.

Steering head - clean/inspect/ repack
-inspect bearing cage for cracks and wear
-inspect races for wear and damage, dimples from ball bearings

Swingarm pivot - clean/inspect/ repack
-measure side play, should be less than 1mm if any
-look for loose needles and broken cages
-inspect inner races for wear

Lower linkage - clean/inspect/ repack
-inspect all inner race shafts for wear
-inspect seals for tearing
-inspect needles and cages
-inspect dogbones for stretching

Wheel bearings and axles - clean/inspect
-bearings should rotate smoothly with even resistance
-a loose bearing is on it's way out
-clean repair axle threads

Chain and sprockets - clean/inspect
-look for torn or missing o-rings
-no binding plates
-shark finned sprocket teeth
-proper alignment

-clean and inspect calipers
-look for worn or damaged lines

SUSPENSION - we all spend a lot of time and money on good components and keeping them at optimum performance takes maintainance.


-refresh /upgrade

Steering damper
-clean inspect for damage
-clean lube pivot points

ENGINE/TUNE UP - the endless pursuit of speed

-A big investment but worth it to insure a trouble free season or to stay competitive. Also a good time to upgrade

Valve adjustment
-slightly more complicated procedure only proceed if your comfortable with cam timing

Oil and filter
-use factory filters and new crush washers

Spark plugs
-inspect/ replace

Air filter

Fuel mixture
-custom map from a reputable tuner

-replace with appropriate coolant for storage conditions

RACE PREP - turn that glorified street bike into a proper race machine

-remove unnecessary components. AI solenoid, brake sw, lighting relays, side stand sw etc.
-wrap, insulate harness
-tie up all unused connectors

Air injection
-install block off plates if applicable
-remove hoses and solenoids
-wire out solenoid

-clear of steering and crash damage

Hand controls
-clean lube all cables and levers
-remove left handle bar sw
-clean/replace grips

As he listed. Don't forget the steering damper! Very important.

But seriously. Loose or worn swingarm, stem and other bearings can give problems in ways you've never imagined. Small crashes transmit a lot of energy through the chassis. Have your bike torn down, maintained, inpsected and ready for a fun full track season.
