:ermm: Just a thought to crunch on. Wouldnt It be cheaper and less of a hassle to just have someone lIke F.A.S.T of Kevin do the port job. After all the books and the tools you will be into quite a bit of money not to mention the $250 + set of cylinders. I think its awsome to say you built your own bike. IF you are somewhat mechanicly inclined then you can due pretty much the entire bike yourself. But something like port work can make or brake the whole build, and no one would think any less of a pro port job on your bike. I am not bieng rude I have had a few ppl now that have wanted to try there own and just end up having to hunt down new cylinders. And there are a few guys on here that have ported there own and been real sucsseful. So what ever you decide works for you. I would just look into both ways and compare the good and the bad before I spent the money. Either way good luck with your build.
