Every little bit of info helps!Also , the later model 2 valve engines use a smaller diameter swingarm spindle than the older sport engines , so when I put the later model engine in my sport chassis I had to source an SS swingarm and spindle .
Hope this helps

Jeff, I just became a member on that site. Very informative over there too. You mentioned tires and ironically, a company called Goldentyre just started producing those 16" tires in the correct size for those old Ducs. Pretty big of them too, in my book. Seeing as those sized wheels haven't been produced in over 20 years!8/10/12
I have a 1990 Sport and was planning on making that engine change myself..
It's actually rather easy..in fact there are spacers in place on the Sport frame that would lead one to believe Ducati anticipated doing just this.
On another site there is a detailed step by step explanation how to make the change...and I could locate it for you if you'd like...
Remember though that the Sport ran with 16" wheels f+r...and good 16" tires (r) are no longer made (at least they were not last time I checked...so wheel changes might be considered as well.
Anyway, if you'd like "directions" let me know...
I believe it was a "Paso" site
