For removing the plugs:

The standard way is to remove them through the "inspection windows" on either side. Remove the 2 plugs closest to each side through the corresponding inspection window.

The trick is to drop the socket and extension down onto the plug first, then put your ratchet onto the extension - when the plugs are cracked loose you can remove the ratchet and remove the plug by hand (using the extension+socket)

Installation is the same, just backwards... Remember to use compressed air to blow out the plug area before removing the plugs, dirt and crap can fall into the cylinder if you don't blow them out.

The tires will be junk, over time the rubber dries out and becomes hard/brittle. There was a proven study conducted that states tires over 6 years old are deadly dangerous.

You're not new to riding, so you should know that good tires are the BEST form of insurance for a motorcycle and its rider (I recommend Metzeler M3's, 120/160)

Check for creases or bends in the fork tubes to see if they are bent, pretty straight forward... If there's no obvious sign of damage, look closely for stretch marks around the triple clamps. Damaged forks are usually quite obvious.

To check the wheel bearings, you'll have to support the bike to remove the wheels.

Once the wheels are removed, try to turn each bearing with your finger - If it's notchy, gritty, rough and hard to turn it's probably best to replace them (they're cheap to fix before they detonate, more expensive when they blow...gonna be a lot more than bearings)

Swingarm uses needle bearings, which can just be greased.

The shock linkage has bearings also, but should be okay, just check for smooth movement of parts.


The carbs:

When fuel dries out it becomes a thick brown/black superglue tarnish that jams everything up.

Be careful when taking them apart as everything is going to be stuck together... Do a real thorough cleaning of everything using compressed air and carb cleaner.

Lube the cables and give the throttle linkage a few shots of WD-40, that should help free them up after they have been cleaned.

To remove the carbs you have to loosen the insulator band screws (on the carb booties) and pull the carbs up and out... You'll probably have to rock them up and down, and you REALLY gotta yank them out of there.

You're right, it is in fact a bitch to get them back on... I can't give any solid advice on that one, you'll just have to wrestle it!

That's all I can type right now, the woman is bugging me to come to bed! I'll check back tomorrow.

Nah, the rear brake is not connected to a vacuum system like a car, it's a closed unit...

Rear brakes are typically quite touchy, but should have a good 1" travel before it gets "stiff"...

What work did you do on the brake assembly, and do you know if it was like that before you did the work or did it come about afterwards?

Another thing,

When you get to the carbs, take the float bowl and slide cover bolts (Phillips head) to a hardware store and replace them with Allen head bolts (get identical thread pitch and size).

The standard Phillips head bolts are very soft and tend to strip out very easily, replacing these will save you from many headaches!

You only have to loosen the outer band clamps, closest to the carbs (each boot has 2 clamps).

Try bleeding the brakes and using new fluid (DOT 4)...

Does it feel stiff using your hand, or your foot? There's a lot more force with your foot than your hand

I still need to do this, but this is a VERY IMPORTANT part if you like being able to take your carburetors apart, ever.

also, regardless of appearance, ALL BRAKE FLUID MUST BE FLUSHED if its been sitting for a few years. all manner of nasty crap builds up in that stuff over time and just, yeah. you probably much like me, want your brakes to function when you need em.

if you havent opened the fuel tank yet, after 6months to 2 years or more, if theres gas in there, it will SMELL BAD. trust me, dont open it inside an enclosed area, do so outside then expect rust inside your tank. dont ask how I know either of those two.

The jets you have are not stock, the stock size is Keihin 135... The 126's you have are Dynojet, it should have aftermarket needles and springs also.

I guess you can't really tell :P
