Its cable actuated: you did check the lower adjustment?
Always measure stack height no matter what you go with.
If the steel plates aren’t burnt blue you can re-use, just scuff with emory cloth AND wash with brake parts or electric contact cleaner---no residue
Barntett clutch springs are by design 10% heavier than stock. If you had stock springs I recommend replacing, your choice but springs take a permanent set over time and you loose clutch engagement pressure-more tendency to slip.
Check all parts for wear, clutch hub, basket, thrust washers, etc…… if it is pulling really hard replace or file wear grooves from hub/basket. Check spring cavities in pressure plate, this is another thing that causes clutch’s to hang up and slip.
Make sure you soak new friction plates in oil and when you first fire bike have it in neutral with clutch pulled IN. This is just me being anal but by doing it you get to control the brake in and seating of new parts.
BTY: friction plates can measure good thickness wise and even look good but still be shit. Always replace all the friction plates and measure stack height.
You forgot Vesrah. I agree with who ever said if it ain’t broke don’t fixe it…. Go with what you now works/like.
The devil’s in the details!
