Soft front suspension,cupped tire because of soft front suspension(this was my problem),tire out of balance,low tire pressure,head bearings bad or out of adjustment.

Do you have the stock barends on your handlebars (i.e. the heavy metal endpieces)? Those barends help to reduce vibration, so if you've lost them you may want to get replacements.

Additionally, there are two common sources of vibration:

• loose engine mounting bolts
• carburetors out of synch

According to the maintenance schedule:
Engine mounting bolt torques should be checked every 4000 miles (6000 km)
Carburetors should be synchronized every 7500 miles (12,000 km)

If you have already considered all of the previous ideas, ohgood has posted a How To that might be useful for you:
