This allows the 749R/848 engine used in Larry Pegram and Marty Cragill's AMA FX bike (and currently ridden by Skip Meador in StO) to be run in StU. Is that your intention? I think that bike is a whole different animal than the Ducati 848. All the guys that bought 749R last year would then need to open them out to 848 cc to be competitive. So, last year's Nuclear Arms Race in StO moves down to StU.Originally Posted by Desmodromico
