if you are even thinking about doing it to save money, don't. it will cost you upwards of $600 to get properly set up, 100 hours of reading and research to get started and a few sets of practice cylinders. look in repairs and mods under the stickie "useful links" for your primary literature. you use a degree wheel to get your timing durations. you need a 90-100 degree 1/8" tool to get into the transfers. 10krpm and/or cheapo 1/4" die grinder with a 1/8" collet will not do it. you can get away with a 1/8" strait for $40-$80 for the rest. shaping is a major part of porting, too. if you peruse the repairs section, there has been a tremendous amount of info posted this year alone. it even helps to study a used set of ported cylinders, too, even if they have exceeded usable bore.

Ok so research out but done cylinders and practice and that will be probably the cheapest way to do it
