Finally got it almost right. Tried the pressure plate again but any way I fitted it it always put pressure onto the plates but I found where it felt most snug. Changed the cable and it's working fine now. No slip at all.
Only trouble I'm having now is how heavy the clutch has become. I'm using ebc hd springs but it's really really heavy. To the point I can only just use 2 fingers. Also, no amount of adjusting can make down changes smooth unless I pull the lever right back to the bar. I've never used all 4 fingers on the clutch and don't want to start either as if I get into that habit I'll be straight off my motocross bike lol.
Stupidly I threw away the ornignal springs, just wondering if anyone knows of any that are similar to standard or where I can find some original ones?
Has anybody ever tried removing 2 springs and running 4? It would work but I'm worried about damaging the pressure plate?
Firstly don't run the bike with only four clutch pressure springs fitted, you will not be able to get even pressure because of the pattern of the spring layout, my guess you would end up with clutch slip again because of that uneven pressure, also, it could cause vibrations at higher speeds as the clutch would be out of balance.
It was designed to operate with six springs.
I have often wondered why people seem to change their clutch springs when they put new plates in the basket? I have heard people say that they lose their tension because of the heat generated in the engine and because they are compressed all the time when changing gears, personally I am not convinced of either of these reasons.
Oil in an engine does get hot because of the heat generated inside, but clutch spring do not get anywhere near as hot or take a fraction of a hammering as say the valve return springs sat up in the cam shaft area (that has got to be one of the hottest areas on the engine), but we don't change them when we do the valve clearances.
As far as springs under constant pressure is concerned the springs in the front forks or the rear shocker take a hammering with every bump or undulation you ride over.
Clutch springs it seems to me are under constant moderate pressure until the lever is pulled in to change cog, don't seem a great deal of work.
An engine revving at 8,000 revs a minute X four cylinders works out at 32,000 piston strokes per minute, or 533 per second, now if a spring ever needs replacing I would think them poor old valve springs sat in that hell hole of an environment were candidates for that, the clutch springs by definition are laying on a sunny beach somewhere have an easy old time of it.
OK it's a bit tongue-in-cheek.
The reality of it is that the clutch springs have a relatively easy time of it, people seems to think that the answer to a slipping clutch is to apply more pressure, of course it might be time to change the springs but why go and put springs in that take 50% more effort to compress then wonder why you clutch feels heavy
Lastly get yourself an old ice cream tub and chuck all the odd bits and pieces that you replace on the bike in there, at least until you know for certainty that all is well with what you have replaced.
I assume that the dustmans been since the springs went in the bin? they come fortnightly around my way.
The image attached is not a FZS600 engine but it shows the environment that valve springs operate in, just above the combustion area and we all know that heat rises
