Hello and i already need help

Hello everyone. My name is Eero and i am from Finland. I recenly got myself a Brutale 989r from 2009. It has 17000km on clock. No mods only gear lever spring and rear hub uprages, full Mv agusta dealer maintance history since it was bought.

So to my problem now. Two days ago i was on little road trip (about 400 km in total) and i was cruising at 100 km/h around 4500 rpm and when i twisted the throttle it started to stutter and didnt accelerate. It went away after i switched to lower gear and the rest of the journey went great.

Yesterday i rode the bike to work no problems what so ever. When i was trying to start it after work it didnt start so well and idled poorly and shut off after giving a bit throttle. I just wish its nothing too big broken.

Couldnt find edit and forgot to add that where should i start looking for fault or just tow to dealer. It feels like its either not getting fuel or spark. I couldnt find much info for my model on internet.

Spark plugs were changed 4000 km ago. Just wondering what could be already broken with my mileage.

Welcome to the family - don't forget to post a few pics of the bike...if it's the 989r it's most likely orange...but not always.

Anyway, 17k on the clock is nothing for these bikes...the problem is the history and that previous owners have tended to treat them like princesses. The bikes need to be ridden hard and across the rev range. @4500rpm, your only just over a 3rd of its rev range. A number of B4 models have often had a slight power dip (I'm going to say around the 4k rev range) - think flat spot. Not uncommon and often resolved with a remap of the ECU.

This Flat spot generally occurs around the same rev range and can (obviously) be alleviated by a different gear choice. It's especially annoying when you hit a corner in 1/2nd gear at the wrong speed and you're sitting on the flat spot.

Try some further testing to confirm it's a flat-spot problem...if not, then we can diagnose the other potential issues - E.g. 17k on the clock and a 10 year old bike means it's average 1900 kilometres a year...fuel rubbers, fuel filter etc... could come into play...but let's start simple.

Cheers

Its red. I will post some pictures when i get to desktop and i get permission to add pictures to album.

I know the previous owner really well and the bike was treated like real princes since new. My previous bike was ducati so i have to try to get used to i4 engine.I got used to ride the Duc at 4k-5krpm when cruising.

Tomorrow i have time to sit down with the bike and try figure out the problem. I have only worked with ducatis and other air cooled older v-twins before so that manual posted earlier will be really helpful. Brutale is way more complicated than my duc was.

Welcome to the family !!!

The 989 is basically the same bike as the 910, 920, 1078, and 1090 Brutales. At that mileage, and (especially) age, I will guess your problem may be fuel delivery related.

Time to inspect (replace) the fuel tank internal hoses and probably replace the filter. That is what your symptom descriptions lead me to.

Problem seems like has solved itself. Could have rain caused these issues? It was rainy night and bike was outside overnight before the problems. After sitting inside two days it started fine and ran like it used to. I took a little ride around the block yesterday evening (around 200km), rode it much harder than usually and everything worked like a charm. I have my 18k km service coming in soon. I will tell them about the issue and to replace the fuel hoses and fuel filter anyway.

To the flat spot, theres a spot at just a little over 5000 rpm where the bike doesent feel as responsive and isnt as smooth as everywhere else on rev range.

Thank you to everyone who took their time to respond and help!

Eeros,

Could have been the rain. Mine's played up occasionally in wet weather. Treat all connections with dielectric grease as you come across them.

Cheers
