well i got malossi rollers 5,5s and i got malossi clutch springs i fitted the rollers and the white set of clutch springs and i lost all acceleration it would revving madly and not go any where fast so i put my leo vincy clutch springs back in and its just revving madly and all acceleration has still gone i can not wheelie it no more but i could with 7,2 rollers but it would rev madly till 30 then go normal. so would should i do?
your bike is gutless so the clutch is slipping like hell.. put stock springs in and try the 5.5's.. it wont rev till your doing about 10mph as its stock springs but you will have a good idea about roller requirement by revs above 10mph once you got stock springs in there.
yeh do what minor said. all you've got to do is fiddle around with different roller weights and leave stock springs in. then once uve found the right ones then you can change the springs to improve set off etc.
i dont have the stock springs only the leo vincy and a set of malossi, and i reckon it would need 6,1s or the leo vincy rollers (what ever weight they are could some one please tell me), also it has a polini variator...
