ok i have a 1991 fzr 600 i am in the process of changing out the spark plugs thats no problem but when i hit about 45 to 45+ the bike wobbles up and down then the second thing is i bought the bike with two led brake likes they only work if the front brake handle is fully in and the rear brake lever dont engauge the lights at all i need help and does anyone have stock tail light they want to get rid of?

I can help with the rear light. I had the same problem. Connected to the rear brake lever is a spring. Undo the spring, then remove the switch from the bike. That is the rear brake light switch. Once off the bike, take it apart. You will notice the switch is simple. The issue you are going to find is the white sleeve inside the switch.on the pin is worn. I took mine off and flipped it over, and it works 100%. I wish I had a photo, but did not think to snap a photo. It's very easy once you have it off the bike.

thanks ill do that tomorrow ill let ya know how it works

works great

Good deal.

On your other issue, explain the wobble up and down. Is it like a vibration, or a pronounced up and down movement. Take a look at your front tire. Is the tread cupped? Meaning, is the leading tread higher than the following tread.

the thread is fine is up and down it feels like your going 120 when your going like 45

Maybe out of balance, or your bearings are bad. Get the front end off the ground. The roll the front wheel. If you can hear the metal sound made by bearings, then its time to replace them. Other than that, I am unsure. I read yesterday that, That Kid here on the forum sells bearing kits. Look him up if you need some.
