it sounds like the brake pipe is blocked up with dirt or somthing,,,take the brake pipe off the rear caliper and stamp on the foot brake peddle if no fluid comes out there is the problem,,,it may be an air lock or just a blockage like you may have twisted the pipe closed doing it up to tightly? or only using one spanner insted of two!!!! if you have closed the pipe up, it would be safer to replace the pipe,,, before it blows out on you! also when you do finaly get brake fludid to the rear caliper,, press the pistons right into the caliper before bleeding the alr out then finaly pump up the brakes,,, dont bleed the brakes to slowly or the air will run back up the pipe,,,,undo the bleed nippel put your finger over the end of it and pump the foot brake about once every second till all the air is out then nip up the nippel,i hope this helps you out

Most likely Alternator or Starter Motor. Perhaps get both lots? Best if you have them out and with you Might also try your BOSCH Auto Electrician if the others don't have them. ,,

Have got electronic ignition? If not replace the springs in the distributor. Cahnge the fuel filters on the side of the carbs real easy job, they r just a screen that get blocked with old fuel.

I changed the category, as I believe this is a Moto Guzzi Eldorado?

See the link for clues in removing the tank. Videos as well.


there is a text file in this thread that will give you an idea


It goes without saying that you don't want your tank full of gas to do this because it's HEAVY and BULKY to move.

Remove the parts I list here and you will safely and securely be able to remove and replace the tank without causing any damage to other parts of your motorcycle.

To properly remove the tank, do the following:

1. Remove the beauty cover from the lower part of the fuel tank. There are 4 screws which hold this in place. 2 are on each side of the bike. After removing the screws, lift off the beauty cover and set it safely aside.

2. Remove the air deflectors from each side of the bike. There are 2 screws holding this part in place; 1 upper and 1 lower.

3. Remove the side panels. There are 3 connectors you must remove. One in the front of the motorcycle under the lights, 1 at the bottom of the side panel, and 1 at the rear of the side panel.

4. Time to disconnect the hoses from the tank. The hose on the left, is the drain from the filler neck in the fuel bung. It's what carries spilt gas out of the filler neck and sends it out the back of the motorcycle via a drain. It is simply held on by compression and can easily be popped off. The center shows the fuel pump electrical connector. Again, gently, lift up on the locking tab catch and remove this plug. The hose on the right with the clamp, is the principal venting hose. With a pair of dykes, gently squeeze the connector together and it will spring open. You can then remove the hose from the tank.

The connector in the lower center, is the pressurized fuel line that so many people seem to break. DON'T PANIC. If you do exactly as I tell you, it will come off so easily and will not even get close to breaking. There is no need to relieve the pressure in the line. It's not that much. The secret of how to remove this connector is so simple. With your right hand, press the connector gently in towards the tank, while at the same time with your left hand, press the black locking collar also towards the tank. You are pressing them both towards the tank. Now, while holding the black locking collar down, gently reverse your force on the fuel connector and remove it from the tank. If your line is pressurized, it will burp a small quantity of gas, so please, don't be smoking or have an ignition source anywhere nearby and also don't have your face right down there unless you enjoy gas in the eye!

I have made a video of me disconnecting and reconnecting this connector. Please look at it and it will become totally clear how to do it.

5. Take a piece of string and loop together the fuel line, the electrical connector, and the main vent hose you just removed and tie them off towards the back of the motorcycle so that they are completely held out of your way.

6. Unscrew the bolt in the front center of the tank.

7. Now, remove the 2 bolts (1 on each side) at the rear of the fuel tank.

8. The tank is now able to be lifted off of the motorcycle and carefully set aside on a nice soft towel, out of the way.

That's it. Good Luck. There are photos in the Charcoal Canister Removal section showing each of these steps should you need photos.

You will need a new simple hose clamp for the spring clamp you removed unless you have the special tool to re-seat the original clamp.

Hi, Jeffrey if you have electronic throttle you have an issue with the throttle control sensor for this scenario you will need your service manual that has all fastener torque specs and a wiring diagram on the back pages, parts fiche, and owners manual if you can't find the best tool you ever bought for your Guzzi, despair not, for a mere zero $0 you can download another one.

what is the original problem that makes you think it is cam shaft problem
If the manufacturer used cheap cams (not likely as it affects the brand name) the engine is under warranty and the cams would be replaced by the company
Find a different service center or contact the manufacturer direct to see if there is a recall out on the engine
consider this --if it is a moto guzzi mechanic that was telling you this , then why was it not booked in for replacement parts under warranty
I suspect that he was trying to get extra money out of you and was not qualified in the product

Bad connection or faulty starter. Check voltage/current to the starter when you press start - should be around 8/9 volts for a 12 volt system - if considerably higher suspect starter, if lower and little current flowing suspect poor connection somewhere. If the voltage is low and current high suspect starter.

Probably have to remove the seat first. Most fuel tanks are retained by u shaped flanges that grip a round rubber puck on both sides of the frame near the steering head. After you drain the fuel, lift the rear of the tank slightly and pull it to the rear, it should then be free to lift off the frame.

Hi, Andrew the best way to charge a battery is slowly. I like to use this analogy, would you rather be awakened from a deep sleep with gentle nudging or a violent kick in the rear.
1. Remove battery and check for corroded or damaged terminals clean any dirt, corrosion or electrolyte that is on top of the battery as this will cause premature battery drain, inspect for cracks and swollen/expanded sides which are a sign of overheating and replacement should be seriously considered.
2. Acid plate type batteries should be checked with a hydrometer with recorded readings for each cell to be compared with after charging readings and for sulfation, the cell will appear milky, and incorrect acid level. Fill low levels with distilled water to upper level and remove acid from overfilled cells with hydrometer until the level is at the upper mark and dispose of acid in the sink mixed with a quart/liter of water.
3. Connect a voltmeter set on the DC scale to the battery and record the reading for comparison after charging.
4. Attach a drain hose that is not pinched, kinked, or plugged to the nipple on acid plate type batteries and let the other end hang into a plastic or styrofoam cup.
5. Connect a 1-2 amp trickle charger that has automatic charge rate reduction if possible and let charge for 24 hours.
6. After charging recheck each cell with a hydrometer a 100% fully charged cell will have a specific gravity reading of 1.270-1.280 and 1.180-1.190 has only a 25% charge battery should be load tested and considered for replacement if necessary. Reconnect your voltmeter and
any readings in the 10-volt range means you have a dead cell and the battery needs to be replaced. Readings between any 2 cells of 50 points or more indicate the battery has failed and needs to be replaced.
7. No maintenance AGM or GEL batteries need to have a voltmeter reading of 12.8-13 volts for a full 100% charge and 12.2 volts is only a 25% charge and should be load tested and replaced if necessary.

Could be running way to lean and the fuel may have too much alcohol or water or the injectors may be clogged/restricted.

I don't know what vehicle/equipment you're referencing here. With that in mind, can you drill a hole or holes through the chassis just below the gas cap to allow water to escape?

Hi, Adam before testing any electrical component in the Starter Circuit it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test because your battery may have 12.5 volts or more but little or zero amps causing the battery to be faulty and must be replaced, especially "AGM" batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Security alarm needs a reset.
10. Starter relay, solenoid or starter circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. The electric starter is working but starter clutch has failed.
14. Check for engine trouble codes.

oil leaks during use indicate a loose bearing adjustment allowing the oil to move past the seal lip when rotating
I would be checking wheel bearing condition and adjustment, oil level in that section and wear groove for where the oil seal lip runs
reasoning is , when the wheel is stationary the oil is not being splashed around and will settle in the lowest places
when moving , if the seal housing is allowed to move separate to the axle position ( wobble , up down sideways etc) then small gaps appear between the seal lip and what it runs on and so oil is allowed to escape
if it is a drive shaft to the rear wheel check the output shaft to the wheel for movement ( bad bearings , adjustment/ preload ) or anything that will not keep the shaft in the center of the seal

Moto Guzzi... | Answered on Feb 29, 2016

the blank one and you can check this out after the bike is running or at least when you get the coil to fire by placing the lead part of a pencil in the gap between the spark plug or a good ground and the gap between the pencil and the spark plug wire so you can see the spark jump to the plug or ground from the plug wire and if the spark flash is on the wire side of the pencil the coil the coil is wired with wrong polarity if the system is a positive ground system. The coil will work no matter what the polarity ie no matter which of the terminals you connect to power and which you connect to ground, the only difference will be a somewhat weaker spark if electron flow is reversed from what it should be i.e. if it is from negative or ground to positive on a negative ground system or as on some older British ignition systems from positive to negative on a positive ground system. The flash will appear on the side of the pencil lead away from the current flow i.e. the flash will occur as the current leaves the pencil lead. Hope this helps.
