Running low RPM, receiving jerking motions.

2013 MV Agusta Brutale 920

Hi all. Having some issues. Idling was fine, but now its jumping VERY little, however pulling away the bike receives a jerking motion. It feels like it wants to cut out, but hasn't luckily.

This has been going on for a week so far and seems to be getting worse. Spark plugs have been changed and coils have been checked (All good). Oil has been changed, but not the oil filter, cant seem to find it.

I honestly have no clue what could be the cause.

@ManiacDray: How do you work on your bike without a manual? Go here and scroll down to your manuals and download them for free:

Your oil filter is in the bottom of your engine sump held in by four bolts and a cover plate.

Read through the engine diagnostics. It might be as simple as a TPS reset.

I have the workshop manual. Unfortunately the link you gave doesnt have the manual for my bike.

The manual says the filter is located behind the coolant guard, but its not. So I did check under the engine for any cover plates that could be hiding the filter. There was absolutely nothing.

TPS would never have gone through my mind, but its definitely worth a try, thanks.

The 920 is basically the same engine as all the other MV 4 cylinder models. The oil filter is a spin-on type on the front of the engine behind the exhaust headers.

You will need the software and communications cable to reset the TPS if needed.

How many miles do you have? Does it run normally other than low rpm/idle?

I used to be fast....now I just dream about it.

Yes the manual shows that you need to remove exhaust manifold 3 & 4. From there you will see that it is located behind the coolent guard. I could not find anything of the sort plus I checked under the engine for cover plates, nothing.

Well it starts fine, idling is fine as well. Pulling away form 1000 - 3000 rpm it jerks and feels like cutting out. 3000 rpm and above it was running smooth. Now this morning it only runs smooth from 5000 rpm and up.

Reset TPS is first task. Look at the shop manual for any MV 4 cylinder for the oil filter. It is not under any plate or cover. It is screwed directly onto the front of the engine....just like on a Honda or Suzuki or Yamaha.

Thanks...I added that manual my collection !

Although it doesn't "List" the 920, everything should be covered for him. I think the 920 just has different size piston and lower spec suspension/brakes.
