stage 2

When I built my bike I took advice I learned from this forum and I broke my engine in slowly and I ran it thick @ 20:1 for about 4 - 5 GL of gas until it really opened up. I was told I would know when it happened and it was clear...now I run it @ about 36:1 I found that it runs best at that mix...
