I drop off my '03 620 for it's 600 mile service today. And now it is time to start thinking of mods.

I want to do pipes/airbox but have been reading of all the trouble/options to get the air/fuel mixture right.

I was thinking about piecing together a system myself but after reading about having to get they bike dynoed and re-mapping issues I decided I want to keep it more simple.

To make things easy I am looking at the Ducati Kit with the Termi high mounts, airbox lid/filter, and chip.

Will this be a install and forget about it situation? Will the bike run right without having to get it on a dyno to fine tune it? Since the bike runs lean from the factory will the new chip with the kit take care of that even though I am adding more air? In short any feel on how it will run afterwards, lean or rich?

I know I may get off cheaper if I piece together something but I'd rather spend the money once and get it right than have to keep getting it fine tuned and dynoed....

Bike is completely stock right now and I don't plan on doing any engine mods down the road...so further mapping won't be necessary.

if you don't mind spending the money, the ducati performance kit should do the job nicely. the ECU it comes with has the appropriate mapping for the performance cans AND open airbox lid.
there IS room for improvement as many have found out by fine-tuning with a PCIII + ECU, but it's not "necessary".

that said, i honestly think that if you don't mind doing a _bit_ of legwork, you'll be better off with a bunch of $$ still in pocket if you go the bit-by-bit route. you can score a set of sil motor cans for around $600, and an aftermarket air filter for $50 or so. the "open lid" is just the stock lid with the top cut off. you can do this yourself for free with a jigsaw and/or dremel. then for the fuel injection, if your dealer's good, they can fiddle with the stock ECU's CO and TPS settings. no, it won't be "as good" as the ducati performance kit's ECU, but a whole lot cheaper. should cost about 2 hours labor = average of $120. so for a total of less than $800, you're golden. if your dealer doesn't know how to tune the stock ECU with the ducati diagnostic computer, then buy a TFI box from techlusion.com for less than $200 and dial it in yourself. sweeeeeeeet...

Strati, thanks for the info. I am all for doing the legwork, and saving money, but I'm still a little worried about all the conflicting feedback out there for the mods I am doing.

Some say the techlusion is great, others say it isn't all that. I've heard the dealer can tune the stock system a bit but it depends on how good he is. And then it may not be perfect for the entire curve. Great feedback on the PCIII but I hear the PCIII isn't available for the '03 bike yet. It is a little frustrating because no one can say for sure yet how it'll work til it's on the bike.

Granted, I understand the nature of the system, and the variables, but I'd like to get something that works right off the bat. Plus, the bike is a daily driver and I can't be messing with it all the time to get it to run right. Money isn't too big a concern in an effort to get things right. But I don't want to spend more than I need to. Either for the Ducati Kit or for the endless tuning sessions that may be necessary if I build a system.

But, I think I will still research things further. I am all for saving some dough. And the research is teaching me tons about the bike. We'll see....

Thanks again....mwb

It is all degrees....considering most run lean, then an inexpensive means to richen the mix suits a lot of people.
As you have seen there are quite a few people who are very happy with this arrangement, including those who use the techlusion. Nothing wrong with it at all.
To a finer degree having the tools to diagnose and adjust the fuel and air mixture is still the only option to get it right.
If you want to keep it simple then the guesswork needs to be eliminated as much as possible.....Getting it right costs what it costs, but getting it close is fine too..... ;)

2003 620ie with Sil Motor high mounts AND a brand new PCIII - check the web site, they just put them up last week.

http://www.powercommander.com/719-211.shtml

They have 5 maps on the web site - the one that worked best for me was the M719-002 "Remus slip-ons and stock or aftermarket air filter". It now runs better than stock with more power from about 3000 to 6000k (measured using seat-of-pants)

I havn't done anything to the air-box. The sils are pretty load, so I'm not sure I want to increase the noise level, but because of the ease of tuning with the PCIII why not experiment? ;)

my $0.02

JB, thanks for the input. I was at my dealer the other day to drop off the bike for the 600 mile service. The tech said he could play with the stock system, TPS and CO (as Strati suggested), if all I want is slip-ons.

Debating whether or not to also do the airbox cause I don't want it TOO loud. So, I'll probably just get cans for now and let the dealer tune it.

Curious, if all you got were the cans why did you get the Power Commander? Did your local shop try to tune the stock system first? If so, how did it run?

How exactly do you tune it with the PC III? I don't have a computer at home? What is needed?

Thanks, again, for all the help.

I wrote this in another post but basically my dealer sucks. They've never adjusted EFI before - the mathesis "machine" hasn't been un-crated yet - they've only seen it done at school. Don't want these guys messing with my bike.

All I can say is after I put the Sil Moto SS Conicals on the bike it sounded great / ran like ****. You'll need a laptop or a palm pilot to use with the PCIII. I downloaded a map off the Power Commander website that got me real close to where I need to be - the bike runs better than stock. Very easy to just download a map to the bike.

There are a couple HD dealers in my area that are certified Dynojet sites, I wonder if they wouldn't mind dyno-tuning a pasta-burner . . . ;)

Jim, thanks again, for the info. I saw the 620 maps on the website, and found a Honda dealer that does PC tuning on sportbikes. So, I will probably get the exhaust now and let my Duc dealer tune it. Then down the road get the PC III and mod my airbox. I'll take a crack at tuning it and if need be I can let the Dyno center dial it in.

Thanks, for the info....
