Instead of buying a bicycle patch kit, or some other kit with an assortment of not necessarily useful supplies, I'm considering just buying a box of Rema TipTop patches and some tubes of their cold vulcanizing fluid. The shelf life of the patches is five years, so I'll split a box with a friend. http://www.rematiptop.com/products/automotive/tube-repair-vulcanizing-patches.html My question is what size of patch would be ideal for motorcycle use, and is there such a thing as too large of a patch? A 2" round patches would seem ideal for motorcycle tubes. One could possibly be slipped over a valve stem to reinforce it, and a larger patch would seem to have a better chance of adhering to the tube, or covering a larger wound better.
