Hi all, here is a question, or two, or three, that has bothered me since I started trying to figure out how to get more air into each cylinder w/o going the forced air route or winding the guts out of the engine. I know there are a lot of smart people on this board and I am hoping to get a few ideas so here we go............ Would it be better to bore out the cylinders to the 810 kit and leave the stock valve sizes, leave the bore size as is and increase the valve area per cylinder OR, just flow the stock head and call it done? Not looking to turn it into a rocket, just bump it up a bit. The machine would be used as intended, an everyday rider with 50% in the city and the other 50% on the open highway. Whaddaya think?
