Don't know what the valve clearances are or when they were checked! Is it hard to do? I've done valves on cars before but they strike me as being a bit easier to get access to. Have just found some other posts after reading yours 'YPVS TONE' and it sounds like this is quite a problem on the FZR especially on the intake side. Looks like i'm not going to be riding for a while. . . . . . Really hope this fixes it

Not been using the throttle with choke. When it does eventually start and you add the choke it dies too, so just avoid the choke altogether Chaning the oil is on the list of things to do.

My 1989 FZR 600 refuses to start when the temperature is below double figures. I've replaced the coils/HT leads, the original plug caps for lower resistance NGK ones, new NGK spark plugs and new battery. I've had the carbs off and given them a clean (but not replaced the jets or floats etc as carb set up strikes me as black magic!!) After some time cranking on the starter it tries to run but never seems to catch. I don't use the choke as it seems to make it worse. Once it is going and warms up it is fine and runs well. On a warmer day it will start 9 times out of 10 on the first try. Any ideas appreciated. Dave

Evening All, The names Dave, been riding for a couple of years and have just joined the forum to try an absorb some of the technical know-how that i'm sure is flying around on here. My '89 FZR 600 needs some TLC. Who'd have thought buying plug caps would be such an effort!! I might even be able to return some knowledge one day
