Ducati Monster Forum

Evening everybody.

I´m going to build a HYM1100 motor for my track day hybrid (749R frame, HYM1100 motor) and among other things I´d like to use Carillo rods. As always with american components, if you can source them in the US and get them home without the customs authorities paying too much attention there´s a saving there.

However, I have not managed to getananswer frpm Carillo, or a few of the dealers I´ve mailed. Anyone out there who can tell me how  much a pair of Carillo rods cost in the US? Part number acc. to their catalogue is DU-906-1>-8M5118S?

If you could also name a good dealer I could contact, I´d appreciate that very much. The plan would be to order and pay from here, and have them delivered to people I know in the US for further transport.

Any advice much appreciated !     

I can call them on Monday.

I bought new bolts this year from Performance Unlimited in England and was very pleased with the communication, including a long talk about stretch, torque and testing. I could have saved money going through US contacts, but didn't have the time and thought it was right to buy from the people who were helpful and had my bolts in stock.

Your US purchase plan will be less expensive, but if it doesn't work as intended - you have a good back up. ...and there's Kämna of course. Dutch Biggelaar is also known to be helpful and they too know their Carrillo stuff.

My rods (LOUD knock on wood) are 90,000 km old. Everything around them have been broken and/or replaced, but the rods have been fine. 

I look forward to follow your build thread (?), seeing you next year and wave when I pass you  [cheeky]

 [laugh]

Will be good to watch, including the build  [thumbsup] ;D.

Evening again.
Speeddog: That would be great, if it's not too much of a hassle. I'm just trying to establish the playing field.

Stopintime: You know you should not speed in the pits :-)
Hope those forks still work well.
As for the Carillos: I sent a mail to your UK contacts as well, and had a reply within a few hours. Nothing from US, nothing from the Swedish dealers a . So you see which way I'm leaning, unless a US deal is really too good to resist.

Build thread: OK even if not a Monster ... ?

Yes for sure. [thumbsup].
I want to see how much power you get from the Hyper motor.

Besides Carillos, what parts are you planning for the motor? Cams, higher compression, porting, lighter internals? Is it an Evo1100?

They really do - fantastically stable - thank you (other than the 'downside' that I now need a slight spring upgrade to match the fork)

Buying from the UK will mean one import tax for you - I paid the UK VAT plus the Norwegian tax since they wouldn't deduct their local VAT (they can, but probably don't know how or couldn't be bothered).

I wish I could use a HM engine in my bike - good engines, maybe only need hotter cams and a Dyno job.

ive asked mark@ducshop about carillo rods and he told me the stock rods on a DS are plenty strong enough. he advised me to buy ARP rod bolts, like $80, for my stock rods. he said they've raced their bike with DS engine on stock rods with ARP bolts and have never had a failure. that's $800 to spend elsewhere. just food for thought.

Thanks for the info, it's certainly worth thinking about. I'll check with Ducshop directly, I suppose.

Any difference in the weight of the rods?

Sorry I was off. Ben fox has the rods for $675 for a pair.

Here's a link from his site with rod weights.

Saved that link .

Thank you very much, very interesting. I can add a bit of info:

Stock Duc 2V (with bearing shells, don´t know why I didn´t take them out): 523 g

Autoverdi (no bearings): 398 g.

The Autoverdis turned out to be pretty much a one-off job for my tuned ST2 engine, intended for my ST2-based track day bike project, which gone from hybernating to dead. However, the motor is complete, and I may have found a use for that motor. If it materializes you´ll know  ;).   

 [popcorn]
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?

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. ;D

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 :-)

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.

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?

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.

I miss my M900.

What do you miss?

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

I dont bloody miss that. ;)

[laugh]

Well.
any progress will be reported here:
