Hi Tonio As Chris says a 900 will go in without any problems, and the exhausts are the same size. and also the carbs and Ignitors can be used I have just fitted the last of the Carb'd 750 engines into a 600 Monster, but for this conversion I had to drill out two engine mounting holes from 10mm to 12mm and then I tapped the holes on the opposite side to M12 X 1.25mm No reason a 900 or 750 injection engine and running gear couldn't be used, or even a later 800 or 1000 but expect to pay a bit for the running gear as clocks and ECUs are coded on these later bikes. I may have a 900 engine and a 750SSie engine and running gear for sale in the not to distant future Checkout the Desmo Due Paddock on Facebook |
