My 1986 FZ750SC has over 95,000 miles on it and is leaking past an oil seal or two. I did pick-up another lower head assemble complete with valve components. Before I do anything I would like to determine the Valve Stem Installation Height without the Valve springs installed.
Does anyone know of this range, or a contact that can tell me?
Hi Robert the only info I have is for valve springs installed force which is 7.3-8.7 kg for intake springs and 11-13kg for the exhaust springs that will relate directly to your valve installed length because that impacts the installed pressure no measurements given for valve installed length sorry hope this helps Karl
vtr: Hi from cape town; new at forum's not at bike building; the insanity is contagious. Recently acquired a "1FU" FZ750 with dropped valves and decided cool to rebuild as a 911conversion sleeper, what we do to ourselves...

grahamfirestorm: Can anyone tell me why my bike doesn't seem to light up after 7000rpm like all the research I did before buying it.She has the standard 4 into 1 exhaust,carbs rebuilt with new jets,seals,floats,2 new diaphragms,all valve clearances checked and adjusted?

grahamfirestorm: She revs round to 10000rpm ok,but there is no urgency with it,my 1987 Kawasaki gpx750 was a lot quicker,and that was supposed to be 10-15 bhp down,ive been told the standard silencer and air filter are to blame but I don't believe that.

Graham : grahamfirestorm. Do you have standard size main jets fitted to your carbs? I would be tempted to go up a size or even two to see if it helps the bike pull stronger at high revs.
