Yeah when I tried doing what you are, it was on a 1972 honda cb175, and I couldnt get the valves to do what they were supposed to do until I had a friend of my dad's look at it, he worked at a honda shop, and the bike was a little old for what they usually worked on, but they got it running... ran lean and melted a piston while going down the freeway, but it ran for a few weeks! haha!
