I have acquired two 1983 Benelli 900 SEIs. I want to tweak one of them to get the power up to nearer the 90bhp+ mark while retaining reliability. I have heard that Honda CB750 pistons help and various diffrent carb set ups. I\´d like to know if anyone has had anything like this done including cylinder head work and what the results were. Also, if it\´s possible to get a sportier camshaft.
