Carillo

[MonsterHPD]

Any progress?

Well, not really. The cost of buying the rodd in the UK is about the same as from the US, but I've not decided if I'll use the stock rods with the good cap screwes ...
The ST motor might hibernate for another year ( budgetary reasons ...).

You could use those ARP rod bolts and polish the rods.
Anyone know if the oem conrods are ok to be cryo freeze treated if its not too expensive?

[MonsterHPD]

Well,
in the end I chickened out / lazy-ed out and ordered the Carillos, via the english retailers. Another bunch of swedish kronor gone .... tuning engines is very cost-inefficient.

As for polishing; I´m not so updated on that since I have not done it, but I think polishing forged components, like rods, is not necessarily good? By doing so the compressed surface layer from the forging process is removed, and it is difficult to hand-polish to an even surface quality, I believe.

Stock-type rods that have been worked on by the manufacturers often have the forge-die flash on the front and rear edge removed and polished, but not the sides.

So what is the general and up-to-date verdict on polishing rods? Personally, I would not do it, but that´s at least partly due to laziness ....

AFAIK, Carillos are still made from forged blanks, machined, and shot-peened.

Forging aligns the 'grain' of the metal all the way through the part.

Shot-peening leaves the surface layer with a residual compressive stress, which helps avoid fatigue cracks.

Polishing removes some or all of the surface layer compressed by the shot-peening and thus defeats the purpose.

I should have been more clear. I was asking the forum as much as MonsterHPD if it was ok if the oem rods were able to have that kind of treatment. It's not something I would attempt myself, but there are tuning shops that do that work and know if it's appropriate. A mate's Superlight had some similar work done to it's oem conrods.

I'm very interested in this build. My tuned HM1100 Evo is a strong street bike without having opened the motor, so it's great to see the performance level someone else's money can achieve.

[MonsterHPD]

OK, thanks.
Speeddogs  info matches what I think I knew.

Any info on HYM1100 tuning is of interest, beeing in the process myself. How's your motor doing, Koko64, and what have you done to it?

Opening the motor for new rods opens a can of worms costwise, but I figured it will be my last expensive build before retiring; and I want to have the bottom end done by THE swedish crank guru before he retires.

I suppose I could start a build thead as well, even if it is not a Monster;  at least it's a 2V :-)

[koko64]

A build thread would be great.
My motor is stock but for tuned intake and exhaust. Its the most powerful 2 valve motor with the most restrictive late model airbox imo. PM sent.
It's the first Ducati I have owned where I didnt feel the need to fit hi comp pistons, port the heads or skim the flywheel. So just external mods. I spent good money modifying two seats for my needs for solo sport riding and touring with my wife. The bike accelerates away from mates' bikes which have much more hp, so I can gap them exiting corners. I love the Evo motor, hotter cams, higher compression, worked ports and lightened internals all from the factory as a last hurrah for the air cooled big bores. The last of the line.  With such light internals, it spins up very quickly. The character of the motor is fierce so it's an angry little bike.

[MonsterHPD]

OK, a build thread will emerge, eventually.
Sounds good with your bike, I also mourn the passing of the aircooleds.
Riding solo only, on mostly smaller back roads I've pretty much fallen in love with my M800 dark. It's not so dark any more with Öhlins suspension both ands and home-made 2-1; good suspension makes such a difference. I even love riding track day stints on it; there's a thing with a bike that's good but still does not overwhelmingly outperform you.

I'm new to the 1100's so I dont know the details. Is the EVO hotter than the twin sparks?

[koko64]

Yes, the changes I mentioned are the difference between the Evo and DS motors. The DS motors are smoother and easier in the wet or in town, but the Evo is meaner. The lighter engine internals of the Evo give it a very different character which I love.
Hotter cams, higher compression, worked ports and lightened internals all from the factory. With such light internals, it spins up very quickly. The character of the motor is fierce so it's an angry little bike.

I miss my M900.

[ducpainter]

What do you miss?

make the beast with two backsing with it until it's right?

[koko64]

I dont bloody miss that.

[MonsterHPD]

Well.
any progress will be reported here:
