I know about the '08 Sporty's new EFI; closed loop, narrow band O2 sensors @ 14.7:1, complaints about heat and roughness,... so what is the Buell's new DDFI 3 specs? Thanks.

Anyone? Do I have to bad mouth Buell for a response? lol, j/k!
Here's the deal, I traded my beloved '05 XB9SX for a '08 1200N. Let's just say it doesn't run NEARLY as smooth as my Buell. Instead of spending $1000+ on pipes/PCIII/air clearer just to make it run right, I spotted a '08 XB12S. Are the new Buells perfect right out of the box? Please let me know soon, and I am sorry I strayed.

Jim, those Nightsters are bad-ass looking bikes.

Keep in mind that the 1200 in your new Sporty has a longer stroke than the old Buell 9 you had, so it's going to have a little more thrashyness to it.

I owned a 2004 1200 Sportster and traded that for my 2007 Buell XB12R. The bikes are comparable in smoothness and in cold-blooded-ness. However, my '07 is DDFI2, and the '04 was a good 'ol Kehin.

I have no experience with the new '08 Buells, but nothing I've read says that any of the improvements make for a smoother running bike.

The '08 definitely runs even better than the DDFI 2 bikes. It's really good, better than the '05's which were pretty nice, now has no TPS reset requirement, no cam timing plate to be misadjusted, more ECU power so qiuicker computations, and a feature that cleans the spark plugs if you foul them. The journalists love the '08's; you'll be happy with one.

A little shot of nitrous will clean up a plug

OK, that's grabbed my curiosity.

How does a fuel computer clean a spark plug?

It uses little tiny brushes.

A feature that cleans the spark plugs if you foul them sounds like the software equivalent of turning off the petcock when fuel is dripping out of the carburetor. If so, Virtual Magic, indeed!

>>>whoa if i buy a 08 buell if i fowl my plug it will clean it for me


Actually. . . that is correct. It's a very cool idea and works well.

It's was added as a feature to clean off fouled plugs from bikes being started cold over and over and never getting cleaned out.

I'm sure it just shuts down the injector,and lets the ignition get the plug really hot to burn off the crap. I may be wrong though, thats how fuel injected cars work, you floor it, THEN turn the key to start. Its called clear flood mode in a car.

The "feature that cleans the spark plugs if you foul them" is probably just a version of flood clear. It cuts fuel when starting if you give more than X% throttle.

This is a great feature. I've used it several times on my RX7 after rebuilds (poor compression and easy to flood out at first).

There have been lots of times that XB's will foul a plug because a customer wanted to hear the bike run and rev it up. Hopefully the feature works well.

Thanks for the responses.
The Nightster was compared to a '07 1200L, and ran the same. Then I took out the XB12Scg. Weight and handling differences aside, I couldn't believe how much smoother it was.

Oh, I pick up the Buell Friday!

To give an example of technology these days, there are some computers that read the voltage across the plug gap and know when you are detonating and hence retards the ignition. Now that's slick!
