Im having the EXACT same problem. Right cylinder will just drop without warning. It'll kick in and out at times but it's always the right cylinder. Much thanks to fast eddy for putting the cdi thought in my head. I replaced the right side coil and still nothing. Haven't replaced the cdi yet but most opinions here point to it. Hmph....guess I'll have to bite the bullet and replace it.
