CBR600F3(W) tacho feed
Posted: 08 Oct 2016, 04:55
Hi
I've been restoring an old '98 CBR600F3 race bike. Long story short, it was given to me by a mate. He high-sided at turn 11 Phillip Island (after MG corner), breaking his collar bone. It then got parked in an apple cool store and subsequently moved again into a hay shed. Recently his folks wanted it removed... and so I ended up with it for free.
It needed plenty of work as you could imagine after spending 8 years in the weather, however it's running again and it's now at a point where I'd be happy to turn a few laps at the track.
There are a few little gremlins though....
The tacho feed comes and goes. I assume there is a loose wire and it's earthing out but I nee to work out where the feed comes from first.
The neutral feed is also a little iffy. When the bike gets hot, the feed drops out (demonstrated by the green dash light flickering then going out), meaning that the bike won't restart as the engine must be in neutral.
I have the standard workshop manual but there seems to be little information in it (on this topic). It does show where the sensor is for the neutral feed and it all seems to be connected ok, although it may be old and on the way out. However I can't find where the CDI picks up the revs from.
Any help would be appreciated.
I have already been asked for progress pics (by my mum of all people) but I ended up engrossed in the process and forgot... sorry.
