It's back!

After nearly four months out the Tuono is finally returned to me.

It's been a long bloody wait and its like having a new bike in the garage. Shame its now the ***** time of year weatherwise!!

Interesting stuff i have picked up. It only apperas to be Tuonos of that year that have had this problem and then only some of them. No RSV's at all apparently.

It's had new crank and pistons, new oil pump, new cylinder head, new ECU.

Just hope the weather in the morning is like today has been so i can give it a run.

bout time too..... now enjoy !

at long last eh dukey ? what year is yours, mines a 58 ( fingers crossed ! )
time to give your wrists a rest !!

Good news Duke!

Enjoy!

Glad the nightmare is over. Enjoy the dry days this winter!

WE can always recognize you when you wear them phsycadellic boots

Nice one Duke,......bit of good news from you at last.

Mine's a 58 reg as well.

It wont happen unless you push the engine hard but then isn't that what they are made for?

Glad to see her home, hope you fall in love again.

The old forum had a post about this - if you look over on AF1 there is some stuff. My mate Windy Martin had his 09 black dream throw the rear big end out with some of the AF1 hooners in France. (He was flat chat at about 160 in top at the time )

As a result - I was awaiting delivery of my black dream, we did a bit of research.

The problem stems from a manufacturing "improvement" made by Bombadier Rotax in 08 (by which time the engines would only have found their way into the Tuono's I guess). They have changed the process used to harden the crank journals which maintains a more accurate tolerance and have stopped countersinking the oil gallery in the journal. This has resulted in some very tight clearances when the tolerances fall that way on the big ends and mains. As a result, it yours is on the tight side the rear cylinder gets hottest and the oil gellery edge can destroy the shell bearings on the big end or mains under hard conditions.

We talked (PM) with Micah at AF1, who is pretty much a genius at engine matters.

He advised taking a bit longer to break the engine in, to generate decent clearances before giving it the berries. I ran mine in as per the book up to the 1000km service, but then built it up gradually to full monty over the next 1000 miles, I have done 4 track days this years and thrashed the arse out of it across Yorkshire or Lincolnshire a few times so it's fine now. I did about 2500 miles around Europe this summer, no worries at all.

Conversely I ran Liz's Tuono in by the "thrash it from new" school of thought. Ragged the arse of it all the way from the dealers, then dropped the oil, new filters etc. It's been brilliant ever since, and for a completely stock moter pulls really well - but of course hers is an early 07.

Just by looking at it sat in the garage and from listening to it running, i have fallen back on love with it.

But...its the trust element i need to get back to make me resist selling it. I'm going for a demo ride on the new Speed Triple in a bit. I can see a lot of elements of the Tuono in that bike.

The way Aprilia treat their customers is quite unbelievable really and i cannot see me ever buying another one however good they are, unless they change their attitude and practices. The spares supply seems as bad as ever though whether this has anything to do with the fact that the Tuono and RSV are now discontinued, i have no idea, but that was certainly hinted to me.
