Dave , Your EFI symtoms sound far worse than mine . My bike has a light surging below 3000 rpm ,but mostly its a hesitation/stall . Certantly I can ride the bikedeebee said:My intention here is simply to add my experience and info to the forum rather than exacerbate a problematic situation. The dealer I purchased my 2006 St3 from here in Perth WA has informed me they have sold several ST3's without problems. However, in 4 months of dealing with them I have NEVER seen a new ST3 in their shop other than mine and the demo they received at the same time (and I've been in their dealership around 2 days per week at least). Funny that my ST3 is an April build 2006 model! What I can say is that having ridden the demo model after mine, the demo does display less of an EFI problem than mine (yes both are 2006 models though I do not know if the demo is an April build batch or not). Mine is, from my perspective after 30years of riding, unridable in city traffic and/or slow speed cornering due to the surging between 0 - 6000rpm. It also has a big detrimental effect on the comfort on long distance touring because it feels through the handlebars like you are constantly going over road surface bumps (which are not there!) due to a cyclic acceleration/decceleration on a constant throttle.
My advice: wait and see what Ducati do to rectify this problem first before buying a 2006 ST3. It's a pitty really because everything else about the model is great!!! .....and ultimately.....caveat emptor.
I have an '06 ST3s with 600 miles on it. I had an '05 so I do have a basis to compare. I have had NO problem with surging on accelleration or backfiring when rolling off the throttle. I've never had it hesitate when starting off.sv1150rs said:Based on all the negative posts regarding '06 ST drivability problems , is anyone NOT having this problem with their '06 STs' ???
