LOOM & ELECTRICS (FORKS)
The lower bush was very worn and could be removed by hand. The lower yoke on the Tiger Cub Competition models were reinforced, the gap between the two parts of the yoke has what looks like a large washer in there to stop any deformity.
Also the Tiger Cub Competition top yoke has a deeper reinforced stanchion locating lug.
I put the lower leg in a vice and clamped the top spring bolt with a pair of mole grips, when I tried to unscrew the spring from the leg it just deformed. I placed the stanchion back over the spring and tried again, the stanchion stopped the spring from twisting and deforming and it unscrewed from the lower leg.
I unsuccessfully tried to unscrew the restrictor from the lower leg with my largest screwdriver. The slot in the restrictor was wider and longer than my biggest screwdriver so I ground down a chisel to match the slot, but this was also unsuccessful. I spoke to Greystone Enterprises and they advised putting the chisel in a vice and trying to turn the leg, this did allow me to put a lot more effort into the attempt but it was also unsuccessful, even with penetrating oil and heat.
