Thank You Goat, very much appreciated and I know these videos will be very helpful.
Well there are some things different to our Morini's we are all commonly running here. Such as S6 - E 3hp, S6 - T 5.8 hp, S6 - S 9.4 hp, and S6 - C 11.3 hp. All the complete stock clutches as far as I know are totally interchange able with these engines. Some of the bells will not cross over well with some of the clutches.
The Clutch you see them using a puller. Theirs is a taper press fit. Ours is splines , and can be gently removed with out a puller.
The nut in the video is righty tighty lefty loosy. The nut to remove on ours is right hand too loosen and left to tighten.
Common jargon for spring washer configuration at other forums is like this (( )) (( )) (( )) ( ) / for washer stack orders. / = a flat washer ( = a spring washer.
Here is a good link Martin & Slater :: Clutch Information
Dean I would not mind a bit if you want to clean up this sticky? Please do!
The sight about spring stacks is misleading..... They are setting up the spring stacks too tight?
Quoting Lean Dean! / / ( ) ( ) ( ) ( ) Now the three shoe is a sweet clutch if adjusted properly which is real easy, you can drop the RPMs by 7to 800 by just removing the .005 shim.You should have Two .oo5 and one .010 which should set the stall at the desired RPM.( remember these engines come from the land of Ferrari and Ducatti)
When changing the shims in the 3 shoe I plug the breather hole and lay the bike on its side then remove the clutch it's alot quicker this way and you don't have to drain the oil every time you make a adjustment.
From what I can see from the video this engine is completely different than what we're using.Seeing from the kickstart gear and the right hand thread on the crank this engine is running counter clockwise which means the're using a much larger exhaust port.Running a engine in reverse keeps the load off the exhaust side of the piston on the powerstroke.I wouldn't use these videos as a referance for the S6, but I've been wrong before.
The puller he's using looks like a cheap steering wheel puller.
I must admeant being the washer stack they are using is different , engine in reverse. It will probably stir up two much controversy. It does show that the stack needs maintained. The screw diver trick [Be careful where you put it]. and stirs us up a good sticky for the masses.
Kevlarr Our clutches will not work with that puller. They do not require a puller. Our clutches are sitting on a splined shaft.
So basically everything is exactly the same just different.
A nice right up!!!!!!!
hey goat, i was wondering if you could answer a question for me? do you know what size, rating or any thing about the morini s6-e 3.2hp clutch springs. i need to get a lighter pair for the two shoe clutch in mine. its a new build and i need a cut back in the rpm ranging. i need to get see if anyone would know. i called around and did`nt get very far. the springs i need to get the clutch to engage sooner. any idea`s or anything would be a great help. thanks, wez
These images are from Morini USA the first is the lighter springs. Morini Franco USA
Or call Hermie at Herdan Welcome to Herdan Corp.! he is a great guy to talk to if'n he's not swamped busy. None the less a great guy to talk to for a second! I think they run a restaurant too? Dunno?
But look at your springs and how thick the coil ribs are should be able to tell.
talked to him today. said he did`nt know what other spring you could use. the factory installed spring is suppose to be the lightest available. after thought i will save some cheddar up and order up the three shoe along with the hi-pro reed valve. thanks and ride on!
