Rear spools on link below at 12,45 Euro
Swing Arm Protectors ConStands Alu 8mm Ducati/Honda/Suzuki black
Front axis sliders is some old Valter Moto's I had lying around in the garage.
The axis is the tricky part, rear hole size left side 7 mm and right side 12,x mm.
I took a M6 stainless steel rod and made bushnings of nylon, tape etc to taper the axis for secure fit.
Stainless dome nut on right hand side, permanently secured with x-strong locktite.
Slide in axis from right to left.
Stainless lock nut on left hand side.
Excellent for cleaning and lubricating chain, but you need to remove it to tension the chain.
Please Yamaha, WHY isn't a paddock spool fitting threads standard on ALL bikes swingarms ???
Similar procedure on front axis, but M8 rod and tapered hole 9 mm left side and some 12 ? mm on right.
