newell, have a look at the links INXS has posted up for you in this thread. Those will give you all the instructions for repairing either starter, kick or electric. Unfortunately, neither one is a half hour job. The easiest one is the kicker, the electric is allot more complicated for removal & repair.
Have you gotten to ride the bike yet? If yes, does the clutch slip, as that could be the problem with the kicker. The kicker turns the clutch, which in turn spins the engine. If the clutch slips, your pedal will feel mushy. Also, a clutch adjustment is an easy operation, and should take maybe a half hour.
You start by first screwing the handle lever adjustment(on the cable that attaches to the lever) all the way in. BTW, best done with a warm engine. Then on the left engine cover is a small chrome cover, about the size of a silver dollar. Remove that, and you will see a screw with a nut attached to it. Loosen the nut( 12mm socket)and while holding the nut with a wrench now instead of the socket ( the socket was to get a good grip on the nut so you could loosen it without stripping the nut)Turn the screw in (clockwise)until it gets harder to turn. That adjusts the worm gear lever that pushes in the pushrod to release the clutch. If you turn the screw too much, you will know by th 'feel' of the screw, you just want to remove the free play from the lever to the push rod. Once you get the 'feel' take up the slack between the worm gear and push rod. Then back off the screw abou 1/16-1/8 of a turn. Hold the screw in place with the screwdriver, and lock down the 12mm nut with the open end wrench , trying NOT to turn the screw you just adjusted. A little is ok.
Back at the handlebars, You should have about 10mm of play before the lever begins to pull in the clutch. Adjust the cable screw for the free play you want.
Now try your kicker. Work better? Let us know. And good luck, don't worry about getting it 'right' as the adjustment can be a little tricky until you do it a couple times.
The front brakes can be a bear, esp. if you got a stuck piston, First try 'flushing' the system with new fluid, as allot of crap get's in there because brake fluid absorbs water. Flush the fluid until new, clean fluid is coming out the caliper. Pump up the lever when done until it feels solid, then see if the wheel turns ok. there should be some drag but you should be able to turn the wheel by hand. If that dooes not help, your probably going to need to rebuid both the caliper and master cylinder.
BTW, do NOT spill brake fluid onto any painted surface, it will remove the paint!!!
