I did a search and didn't pull up anything on this topic.
I just pulled my stock Motobecane 50V engine. It runs well. I plan on replacing the mounts, porting, polishing, swapping to a Dellorto 15.15 and a Ninja mild exhaust.
While it is out I was thinking of milling either the head or top of the jug, whichever looks right. Does anyone know how much to take off to boost compression? Will I need to run higher octane fuel? Will a high compression engine still run with the bigger carb and exhaust? What jet will I end up needing?
I am not really looking for a big boost on speed, but I do a lot of hills and I want power to try and stay at 35 mph instead of dropping down to 15 mph.
Thanks, Terry
