Hello. I have always loved Italian motorcycles. Yesterday I bought a motorcycle from an owner who treated his motorcycle friend with a devil-may-care attitude. Externally and technically, the motorcycle is in poor condition.

486708


The main breakdowns of my MV Agusta Brutale 750 already:

  1. Motorcycle front fork oil seals are leaking.
  2. The radiator cooling fan does not turn on.
  3. Sometimes, when turning the key in the ignition lock, the panel does not light up and the motorcycle will not start.

I would be very grateful if you could help me navigate the forum and find answers to questions to solve the above problems.

PS. I live in Estonia, there are no shops and MV Agusta services here. It is very difficult to find specialists and spare parts, I hope that I will find support on this forum. Please tell me the YouTube channels for MV Agusta Brutale 750 repair and online stores, where you can search for spare parts, both new and used.

@Naabrid: First welcome to MV Agusta ownership.

These bikes are fairly easy to diagnose and maintain. You can obtain your manuals here: MV Agusta Team Double 3 Racing

When posting about your bike, it is helpful to state the model year. This gets us to the correct references. You can add the model and year to your signature line through your User Control Panel.

For your fork seals, first try a Seal Mate cleaning of your sealing surface. That seems to cure 90% of seal leaks.
For your dash and start issues: This sounds like a poor quality or dying battery. The first thing to do there is to install a fresh and properly initialized Yuasa YTZ10S battery being mindful of the polarity and wiring connections. You should also check/clean/tighten the connections on the Starting Solenoid. THis lives behind the battery and has been a point of start failure.

For the radiator Cooling Fans, there ae several things that can cause this issue: Relays, Fuses, Wiring, and the fans themselves. What have you tested so far?

Welcome! Sorry to hear about the sad state of your MV. It looks like it's in decent shape at least from the photo. Once you start working on your bike you'll get attached to it like everyone does when they buy an MV.

"Search" will be your friend as far as navigating forum goes.

Welcome to the family !!!!
Your Brutale 750 looks nice in the photo. A little TLC will make her perform as she should.
Follow silentservice703's recommendations. Get the manuals first off. You will find the MV very easy to work on and parts are available from Europe at several on-line resources.

One more suggestion...carefully grip the edges of your headlight glass and give a hard pull....you may find it pops off into your hands. Don't drop it !!! Now you can glue it back on with some seriously strong adhesive. A search of the forum will yield many suggestions as well as tales of sorrow when the glass fell out unexpectadly....it is not available separately and is a very expensive repair if needed.

Welcome from Philadelphia

Add to your list -- make a checklist from all that we recommend.
Your bike should come back to life soon. Step by step. Be organized.

Consolidated list of topics: Not all will apply to getting your bike running

Parts:
StarTwin Trading | Benelux | MV site sponsor

Rear Seat: Simple fix and often overlooked. Attach a cord from the frame to the seat. They can fly off if not secured by the latch. Finding a replacement seat is very difficult. The security cord will save you from a simple error. Just make it long enough so you can still open the seat.

Brake/Clutch: Change your clutch and brake fluids with fresh unopened DOT 4. No air. Inspect your pads/rotors first.

Coolant: Inspect your pressure cap for any corrosion or damage. Many here use Engine Ice. Do not fill past min mark in the plastic expansion chamber. Inspect the hose connections for leaks.

Engine Ground: Clean off any oxidation to where the negative wire from the battery attaches to the engine case. This I often overlooked and can be the source of odd electrical problems. You need solid ground to start your journey.

Tank: After you handle much of the basic maintenance procedures and get a general understanding about your bike the tank should be next. You should replace your internal fuel hoses and a fuel filter. Clean the fuel pump screen under the pump. Be careful it's a fine mesh. There are threads about this overall process.

Air Filter: When you have your tank off take a look at your filter. For good measure, it's probably best to renew.

Oil: yes, change it. Inspect it for evidence of internal damage.

Chain/Hub: This area can be looked at once your bike gets started.

Tires: After you work out the basics. Check to see if they are hard. Given the previous owner was hard on the bike I would also think the tires need changing.

👋 @silentservice703, @Figifister, @esq'z me, @Edward, @XPARAUK, @MacStrine Thank you for the warm welcome and first tips.

The motorcycle sometimes works well, sometimes it is very bad, most likely a problem with the electronics.

First of all, I ordered the front shock absorber oil seals, spark plugs, all fluids, and filters. I will wait three weeks for the air filter, everything else will come on Monday, I will change it.

Next step, I'll take the electrician. Logic tells me that computer brains can’t work or don’t work, if something on the board burns out, then this is final. Hopefully, it's the wiring somewhere.

It is difficult for me to describe the problem in words only, if you do not mind, I will shoot a video and attach a link to the video in my questions so that it is clearer and you can give more accurate advice.

PS. You can feel free to contact me if you need help on my part, I described my competence in the About Me section.

Those are all good things to do.

As far as the electrical system goes. Look for bad grounds. That's always an easy place to start.

@Naabrid the Service Power Unit is a known electrical trouble spot on your bike. Here is some reading for you:

Oh I forgot... check your side stand bolts/oil pan. They loosen over time. Easy fix.
