Hi Everyone,
I joined this forum expecting to find people asking about the problem I have, having been told that it is a common problem. I haven't opened every message, but at first glance I don't see anything similar.
The problem? - My CB750Four K7 (1978), runs beautifully- until it starts to rain! When it rains, or even if there is a lot of spray from a wet road, the bike starts to run badly, backfires, intermittently runs Ok, then bad again, and will conk out completely. It will then start up again, but continue to run badly. I need to use the bike daily, and here in the UK, a bike that doesn't work in the rain is frequently useless.
I've had it looked at, some parts replaced (supressor caps), but has not cured it. Any suggestions?
