I am looking at buy a 1999 rt 1100, it has 'cupping' on the front tire, what causes this?

Look in your owners manual there should be a code when you bought the car if you still have it.

after removing the front seat the back seat lifts up from the rear and then is removed by pulling it backwards

The factory pressure is on a sticker on the frame by the side cover. If you run 35 PSI front and rear you will have less trouble with tire cupping, better cornering, and longer tire life.

cupping is caused by, underinflationand/or mechanical irregularities such as out of balance of wheel or tire, and a bent or damaged wheel. have a good day !!

remember that when you put hid. you have to buy the whole package thats why they made it like that. so only the hid bulb wont work with out the right amp. when you have both hid bulb and the amp. you will connect the amp to your battery n one of the cables to your head light positive wire. this will allow you to still use your switch from your handle to now turn on n off the hid. also you will have to buy a hid bulb made for your bike, do not buy any hid on the street even if they say that is universal n all that **** bcuz its not. buy the one for your bike model so it fits perfect and it locks by it self, like if it was a factory bulb. So you connect the bulb to your hid amp plug and one cable from the amp to the positive wire that comes from the bike to the factory bulb and the other one to your battery.

depends. if anything that loose is not so good.but some brake are design to have something loose.u can check your brake sometime there is a bolt holding your brake calliper ,cover /wrapped with a small rubber tube or washer.because some brakes there is a gap and allow your brake calliper to move a little when it brake for full brake performance.

Yes, you should be concerned anytime the brakes on a bike act or look strange. Safety First. Have a dealer take a look at the brakes.
