so I just got 2000 monster 900. I suspected some issue though.
sometimes when I stop at the light, I feel a lot of vibration from the handle as I push the front the brake harder. (close to 0mph, not while driving)
I was taking nice curve around 70mph. the front wheel wobbled little bit and it scared hell out of me. (no brakes) it happend again when I was taking a corner and I applied little bit of front brake and it wobbled too (but I guess it was my mistake which was kinda dumb, using brakes while taking corner )
when I accelerate over 80 mph, I feel some vibration from the front wheel and it makes me not accelerate anymore.
so what should I do to fix this problem?

How are the tires?
Any visible 'hits' to the front wheel?
Taken the wheel to balance?
How's your front suspension?
What's your weigth?
Trying to help...

The vibration from braking is a fairly common complaint and is usually from an uneven deposit of brake pad material on the rotors. The fix is to remove the rotors from the wheel and clean them really well (make sure the rotor can move on the buttons) and then re-bed the pads with 6-8 very hard stops from 70 or so, to almost but not quite stopped. You should smell the brakes while you're doing this. Let them cool off to normal temp and you should be good.
The wobble could be from tire pressure, worn tires, head bearings, swing arm bearings, wheel bearings, geometry changes from ride height adjustments, input from you, lots of things.
How many miles on the bike? How complete are the maint. records. How comfortable/knowledgeable are you working on bikes?
the front tire pressure was 1.8 bar and 1.7 for the rear. manual says 2.2 for front wheel and 2.4 for the rear.
I put little more air since it was hot outside (might go down during night)
I was taking nice curve again (leaning in about 20 degrees?). I saw this jeep trying to race with me.
I was going 70 mph and felt little wobbling (kind of like shivering). Since the bike wasn't perfect and I've been with this bike for only 2 weeks, I didn't wanna do stupid things to impress these guys.
I guess I should ask mechanic to inspect it when I change sprockets and chain.
