it seems after all that hassle with the bike, it was just plugs. i took the plugs out of my seized mc 16 engine and put them into my bike and the two cylinders fired up perfectly. i have another question, the plugs are b9ev are these suitable??. the thread lengths look the same, spark gap is similar but the electrode looks like an iridium plug. i am paranoid about this because i dont want to have melted pistons. thanks for all the response.
