[Ducati] Hard starting 99 900SSie

If you do not have an O2 sensor and I am pretty sure you do not then you 
might take it to your dealer and ask them to run it on the exhaust gas 
analyzer and set the computer for the new items installed.  My 999 was very 
lean and I did just about everything you did.  They only charged me for 
about 3.4 of an hour so it was under $100 for the peace of mind it gave me.

Group,

First post and relatively new to Ducati, so bear with me.  I have a 99
900SSie with 8,000 miles.  I love the thing, and recently upgraded to a
K&N air filter, Ducati Performance titanium slip-ons and the
corresponding performance ECU.  Before these changes it had always been
an easy starter - battery is strong, turns over nicely, etc.  But since
the ECU and exhaust changes when I first start it (wit the 'fast idle
choke' open a bit) it starts fine, then it dies maybe 30 seconds into
the warm-up.  It often takes 2-3 more tries to get it running, each time
giving it a little more fast idle.  Once it is warm and running
everything is fine, and the performance ECU seems to have upped the 'fat
part' of the torque curve to 6,000rpm, and has taken away the 3,000rpm
cough and studder.  Any ideas? I'm worried that the new ECU has changed
the fuel mapping in a way that might damage the engine.

Thanks,

Corey in Collegeville, MN
