Just remove the lever, gently pull rubber boot out of the body, take a snap ring pliers,and remove the circlip, and pull the piston out of the body. Use the piston as a reference to install the seals correctly on the new piston. Be sure to take out the screw in the reservoir, remove the reservoir, and clean the fluid return pin hole ( Must Be Clear) , next to the large fluid feeder hole. Also using a dowel covered with a lint free cloth gently wipe out the piston sleeve being careful not to scratch the walls ( Do Not Hone The Master Cylinder or it will be ruined). Coat parts with brake fluid before reassembly in reverse order. Cover bike with plastic and put some old rags under master cylinder. Before tightening brake hose bolt, fill the master cylinder with dot 3/4 brake fluid and pump the lever until the master cylinder is pushing fluid out the end where bolt and hose are loosely connected, now tighten bolt holding the brake line on. This will aid greatly in bleeding the system.

Cbx 550 fires on 3 cyclinders for about 2 seconds the dies, wont run for a period of time, i cleaned the carbs, also the bike had been sitting for about 4 years, any help would be great.


Clean fresh gas? Checked the spark? The spark plug wire ends should be replaceable. They usually just twist, or unscrew, from the wires. They can get corroded or just plain wear out just like a cars spark plug wires do.

Front brake lever has zero resistance, and does not work. fluid is full and pads r fine.HELP


I would suspect a faulty brake cylinder or air in the cylinder. Remove filler cap from cylinder on handlebar and quickly squeeze the handle, watching inside that cylinder for bubbles and fluid movement. If neither are present then you may have a bad master cylinder and need to replace it.If you have air, then you'll need to get a master cylinder bleeder kit and bleed the air out of the master cylinder. The bleeder kit will have specific instructions on exactly how to bleed master cylinder. Also - if, when you remove that cap, it looks like oil floating in the reservoir then somebody mixed brake fluids and wasted the o-rings and rubber in the front brake system - this is really bad and you'll need to replace all rubber seals and hoses for the front brake system as well as flush the system with the proper fluid.

Does the clutch lever have resistance whiles depressed?
Put your bike on the center stand, select any gear say 2 or 3 , press the clutch lever and thn rotate the rear wheel harder , it may release the sized clutch plates.
Hope this helps!

Bleeding front brakes


Your $7 bleeder kit typically has a near useless one valve in it. Forget the kits such as these, they usually make things confusing for you.
Firts, make sure all teh brake lines are tightly connected and in good condition. If the flexible lines are over 5 years old, conside getting new ones made/fitted. Stainless/braided lines look good but are NOT necessary for any road bike.

All you need is a long piece of clear hose line (fish tank air line tubing usually works well) that fits the top of the bleed nipples very firmly. The hose should be long enough to hang over your handle bars, or be suspended by a wire or string so that the open end is higher than the master cylinder. You can use two such hoses and do both front calipers at the same time if you wish.

First, manouver the handle bars so that the top of the master cylinder is as level as possible, even to the point of undoing the grip clamp and rotating the whole assembly around the handle bars a bit. Then fit the clear hoses to the caliper bleed nipples.
Remove the top of the master cylinder reseviour and make sure the fluid is topped up. Watch this level the whole time, it is important that the fluid level never get below half full or you risk reintroducing air into the brake lines again. Never reuse old fluid, and always filter any new fluid that has been in the brake system before (run it through a new fuel filter if you are that hard up for money) you reuse it.
Then crack open the bleed nipples on the calipers so that you see fluid start to rise up the hoses ( which is why you want clear hoses). You can pump the lever a few times to get things happening quicker, just watch the master fluid level!
Keep pumping the lever and topping up the fluid level until the level in the tubes is at the same level as the master cylinder. Leave the bleeder nipples open and leave the bike alone for an hour.
After an hour, close the bleeder nipples and top up and refit the master cylinder reserviour cover.
Use a jar under each hose to catch the fluid, remove each hose from its bleeder and let the fluid drain out into the jar. Ditch the used fluid.
Reset the grip to its proper position if it was moved and test the brakes. Pump the lever two times and then release the lever for a few minutes ( at least 1 minute) If the brakes are still soft or wont hold pressure ( if you still have to pump the lever to get pressure, dont ride the bike!) then suspect worn master cylinder or buggered seals.
