Seeing it is so hard to buy individual 7mm id shims, I am going to get a few hundred made.
What sizes does everyone want?
Order is going in for January. I should have done this years ago when I had a Gasgas.
Maybe I will make up some mini kits based around common valving mods/settings when I work out what they genereally need. And then I can also sell loose ones too if I can keep the price down by buying in bulk.
