I have been having top end problems with my 83 205r atc _ it falls on its face at top end. I rebuilt the carb tried all kinds of sparkplugs and no better. someone in a forum told me to replace the pick up coil. Does anyone know where to find one? I have been all over e bay and bike bandit and had no luck > can anyone help?

 

I'm the one that mentioned the pick-up coil. try this link and see if it's still avail. If not, let me know and I might be able to find a used one.
