Hmm, you’re wayyyyy off base trooper.

You have no friggin clue what this is all about, do you? :P

Ok, what is meant by intake is not the intake-manifold (The thing that bolts to the carb) but the intake that is IN the cylinder, in the bore as to speak. (I hope you know what the bore is). Never raise an intake, it will make you very very sad if you do. You can lower it (make it go more to the base of the cylinder)

By exhaust they don’t mean your exhaustpipe, but the exhaustport. Again, it is in your cylinder, in the bore. You need to modify the window in your cylinder wall to the new specifications.

The transferports are ports that are in your engine-casing and in the base of the cylinder. They move the fuel from the crank-case to the combustion chamber.

But please, do me and yourself a favor… If you don’t know EXACTLY what you are doing, don’t do it. You can very easily turn a perfectly good cylinder into an ashtray.

Have you tried other tuning options yet? Like an expansion exhaust, bigger carb or high compression head. Try those options first, in this case it will gain you more MPH than messing with the ports.
