As per owners manual 338cc  at 15 w   with forks fully bottomed measure from top should be 182.5mm. oil weight varies on conditions lighter for less heavier for more damping . Iain

The book says 182mm but you should run it up a bit higher. I have mine set at 135mm and it's a bit too firm. I'll soon drop it to 145mm which I think will work better. 15w oil.

Teknik go as high as 130mm from their webpage but I'd try the 145mm first. Good Luck!
