i beleive you can change the tension spring but that’s about it.
better to get a second hand unit then you can change the x3 springs to malossi tight ones.
i have bought a lot of parts from moparts and are an excellent supplier, and a great bike builder.
Yeah the tension should be exchangable.
I have now found clutches second hand in good shape. Both 90mm and 100.
So i just have to ask, is it any profit with 90mm clutch instead of 100? like higher topspeed or something?
Or is 100 better on all ways?
