Hi All, Let me start by saying that I dont have a CRF. I am from India and I am working on an upgrade for my 2008 Hero Honda Karizma. Its basically a CBF150 with a CRF230 engine. I wanted to know what bore would be best suited for a daily use with a higher power. I found a guy who offered me 68mm, 70mm and 72mm kits. Can anyone help me out with their experience on bigger bore kits for 230?
Thanks in advance!
