front end

When I go around a left hand corner at moderate speeds the front end wobbles. What could it be?

Possibilities:
Triple tree bearings worn and /or need adjustment.
Swingarm bushings worn
tire(s) worn or need balancing
front bearings worn and/or need repacking
the dreaded Kaw front end wobble-call for an exorcist.Lol.bj

bent rotor.

Motorcycle Wobble Causes

There's a LONG list of potential area that can cause this.

These are not in any particular order
Wheel bearings
Steering bearings - repack grease, check tightness
Swing arm bushings/sleeves/bearings - replace is worn, repack grease
Fork springs aging - check spring length
Unequal fork oil - if seals leak, then your damping can be ineffective
Rear shocks aging, damper leaks - if you have oil leaking from the seals, the damping is toast.
Worn Tires/Mismatched tires/tire pressures/wrong size tires
Wheel alignment - don't trust the chain adjusters - I visually align the wheels.
Bent rims/broken spokes - get the wheels off the ground and spin them - check for runout / damage
Front disc warped - check for runout

Steering & swing arm bearings are very common problems, but so are tire issues (pressure/mismatch) and wheel alignment.

then do the rear end.
