Last spring when I just had bought my YZF, I had a similar fault after first time I washed it. When I turned around the key the nedle jumped up and stopped on 15000 (the engine was not started). When I then started the engine it stabilized on the right RPM, but it was jumping up and down some times. I opened it, but could not see any water, but spendt a few minutes with an hairdryer, before I put it together again. After that this has never occured again, so I guess that a little bit of humidity can give symptoms like that.

Hi again, and thks again. Just been out for the last trip this year, onely for testing. Was raining cats and dogs, and the front fender is disasembled. Yesterday it was snow on the roads. Guess if I was wet, but it was fun anyway, when the bike is working OK at last. Attn. Sheeny7 Thks for the weblink. Have allready made me an account on the streefightersite. Lots of nice pictures. Guess it is possible to get some ideas there. And a few tips if I need. Attn. Barden The race system You have, how old is it, and is it in nice condition? Schratches/bulbs etc. Do You have pictures of it, both mounted on the bike, and disasembled?

Thks for all help. Took me an hour last evening. Demounted the cover who protect the wiring on the exupvalve, and the "wheel" which the wiring is fastened on, was loose. After tightening up the screw who holds it, everything worked fine. Sadly this years season is finished. Guess the winter will be used to finish the streetfighterproject. Thks again for all help.

Thks for quick reply. I have not had a chance to try out the tip abowe, but I guess I´ll have to take a trip in my garage this afternoon, after kids bedtime. If this is something which will give me lots of headace I might vil change the wole exhaust-system with one without exup-valve. I bought the bike (cheap) last spring, with some damage, but onely on the plastic (fairing), and I am building it to a streetfighter. Rgds

Hello. I´m new at this forum. I have the same problem as You describes, with my own YZF 750. Had the bike in a workshop in Molde, and the mechanics had never heard about a problem like this. All cables in the ignition system, the coils, spark plugs etc was contolled, and the mechanic concluded that it had to be the CDI-unit. But when I replaced the CDI-unit, it was all the same. Have You found out of this problem. Sees You were told it could be the exup valve. Please tell me if You found out of it.
