My crappy aftermarket oil cap broke and I had to remove it including the o-ring and the black plastic ring that keeps everything in place (looks like they are glued togheter).
I normally always have a replacement, but I just realized that the replacement is under the seat of the other bike... a couple thousand km south of London.
I do have a champagne cork in place now that holds well, but I'm not exactly sure that a cork and some cloth is the best way to seal the engine
Is there any shops in London, open on a Saturday, where I can find the spare parts (plastic oil cap, o-ring, etc)???
