sv650 tuning

[antony]

hi i have removed an engine out of an sv 650 and would like to find out more about tuning the head at the moment its making 72bhp i am sending the cams off to kent cams to be reprofiled and having a three stage cut on the valve seats i would like to know more about cleaning up the inlet tracts etc maybe boring out the throttle bodies or fitting bigger ones and anything else that anyone considers a good mod as i dont want to add a big bore kit i work for an engineering company so most stuff can be machined etc

cheers ant
