Thanks for merging these i was even starting to get confused.

i appreciate all the glib, it's still good information. But i am curious about the catty and the noticeable rusting on the outside of the pipes and housing. Is this somehow normal?

i realize the effects of octane not being directly related to power (more so now, thank you all!) but do understand that if i run low octane i can eventually hurt the engine, thus affecting its performance in the long run. I do not want to run out and buy any performance enhancing aftermarket parts because (yet) because i don't want to loose my warranty. i don't have another 11-hunny burning a hole in my pocket which is why i want to keep my engine in tip top. Also note that the unconscious incompetents at my dealership emphasized the fact that i should run a higher octane fuel in this bike for its longevity.

so, bottom line is if i am doing what i was lead to believe would be good for the bike (higher octane) am I actually hurting it? like i said i want this bike in tip top so that in two years when the warranty is out i can load it up with aftermarket parts and feel the difference.

thanks again everyone you have been great for the feedback!

Chris at CA Cycleworks (who can be trusted to know what he's talking about) generally recommends 87 for stock Monsters, and says that above that you get carbon deposits. I generally run what passes for premium here in CA, which is 91, on the theory that while 87 would be sufficient for most uses, a want a little extra resistance for hot operation, since I spend more time than most in heavy traffic, which is hard on an air-cooled engine. However, when I had the heads off at 122,000 for new piston rings, there were definitely carbon deposits in the combustion chambers that had to be cleaned off.

I'm still going with the 91, though. I've never gotten any pinging with that octane level under any conditions.

Note all numbers here are (R+M)/2. European numbers (including the ones in your owners manual) are measured differently.

I can't say anything helpful about your cat rust problem; mine is an older model.

How about posting pictures of the "rust"

Grifo · 05-08-2007, 03:51 PM

I have been using 87 on my S2R even after the full exhaust system and airbox/filter with no pinging or any problems.
I get a constant 120 miles per tank I used 93 once and I only got 90 some miles.

How about throwing some JP-5 in your bike.

I would love to see how that works.

i'll put up some pics later tonight. other than that, i'm convinced that i need 100% ethanol (moonshine) in dis mufucka, yo. this way i can siphon some off when i need a pick me up and i'll be all tree huggin like.

Just don't drink *while* riding. ;)

Some years back, the Russian air force had a spate of accidents, which turned out to be due the fact that they were using ethanol as hydraulic fluid, and the mechanics were drinking it instead of putting it in the airplanes. No bueno.

Ha, that's too ironic. leave it to the ruskies to pull shit like that. Nazdrovia, Mipiyania!

ok, so iactually posted these in the Ducati gallery for some reason and will have to remove them at some point.

Anyone think i'm just overreacting here? possibly, i guess but my 97 bandit never had this kind of issue and i anly paid 1/4 the Duc for that one.

PhilB · 05-09-2007, 12:05 AM

I'd guess that it hasn't been run nearly long enough hot enough often enough. Short trips can build up moisture in the exhaust, and especially in the cat, which needs to get good and hot to work properly. Perhaps at some point in shipping or storage some water got in the pipes and sat. I'd recommend taking off the exhaust system and cleaning it out well, and then make sure to ride it long enough to get it fully up to temperature often (at least an hour of regular, or half an hour of fast, riding; at least once a week) and see if that does the trick.

Italian stuff hates being left to sit; it loses its will to live.

Just put a full system on the bike and get it over with

I felt I should give the update on this even though it's not resolved by a long shot. I took "her" in the the dealer for the 600mi service and showed them the problem. they agreed that this was unfortunate and as i expected they had no idea what it was from. they called DNA and apparently were told to "try and clean the rust off and wait to see if it continues". What? When i picked "her" up all i got was a well polished exhaust with either rust stains, or in more inconspicuous places, still rust. So i sent emails to DNA and Ducati Italy (i know, a bit much) and even called Cupertino, but had to leave a message there. I am hoping that by contacting DNA personally that they will be nice enough to call the dealership and tell them to do something that makes me happy and do it sooner rather than later.

I don't know about anyone else here, but i feel that the customer service is a bit lacking with DNA so far. If they have never seen this problem before they should treat it seriously to find a root cause and help people who it happens to in the future. If this is something they HAVE seen before they should fix and/or replace the part(s) right away. After all i did pay several grand more then the Jap bikes for this one and think a little butt kissing is in order. Don't you?

McNair · 05-17-2007, 08:42 PM

my s2r did the same thing. a cat has many square inches of surface area in it.... many more than just a pipe... so i'm gonna go out on a limb and say,

copious amounts of condensation may be causing your problem. all exhausts do it. you ever see the puddles left behind at stop lights? (not a dickhead question)

it's just that, on a bike, it fucks up the parts you can see.

motogpfan · 05-17-2007, 09:31 PM

I'm with Cyrus, get a set of headers and be done with it...
