Fork seal leaks, splendiferous idea

seems so easy to copy by cutting a coke bottle, (plastic one rightdoh)

coke bottle is a bit thick, I used to use a strip of 35mm film negative, which was the perfect strength and thickness, but not easy to get these days!

Yes, Coke bottle is way too thick. Ive used the 35 mm film trick. Didnt work, but the idea was good enough.

Ive since invested in a Seal Mate. Dosent cost much and takes up little space.

think I'll try cutting a water bottle, the paper thin ones....I have plenty of 35mm film in the freezer but that is discontinued film which I keep as if it were gold:D

Use feeler gauges.

Yup...

0.10 mm

Happens to be the same for my valve clearances too :)
