New clutch woes - help!

[Fazerider]

My next plan is to try fitting half Genuine Springs and half EBC, 3 of each, offset evenly, to hopefully achieve a happy medium. Anyone else done this, or foresee any issues with this plan?

I did try that, though I’d bought springs that were probably far stiffer than the EBC ones.
It stopped the clutch slip, but I found the lever action was still too heavy so went back to 100% OE. The slip is only an issue for the first few miles, once the oil’s warmed up fully the problem goes.
If your EBC springs are only 30-50% stiffer than OE a mix of 3 of each will probably be a good solution.

Are you sure you have the plates in the right order, especially the friction plate that comes after the anti-judder spring? This is a different diameter than ths rest. I had mine in the wrong place and my clutch coukd reach neutral but wouldn't disengage.

When you say the one after the spring is a different diameter do you mean thickness or the actual diameter of the 'friction plate disc' - I fitted my new friction plates and never noticed any odd ones .

Chain tension should be 30-40mm according to Yamaha. Personally I find the FZS very susceptible to getting the wrong tension. Too tight, it wines, Too loose and it clonks when you change gear.

The half'n'half EBC/Yammy springs experiment didn't really work. Still dragged load when hot and still heavy on lever action. Gone back to all Yammy springs and just dealing with the clutch slip when cold. Seems to hold up alright when warmed up though. Couple of laps of Brands Indy circuit certainly got tyres and clutch warmed up enough to behave.

Did notice the EBC springs were longer than OEM ones, 39 vs 38 cm < sip  ;-) > And for some reason the Haynes books quotes normal length as 34mm!

Might try some other brands in future, see if i can find a half way house.
