How'd you manage to plug it up? Is that common?
Its technically a temporary fix (more so on 2 wheels)
You can buy string type radial tire plug kits from anywhere for less than 10 bucks, I recommend one with rubber sealing compound/ream tool/ razor blade (cut excess string). These are must haves on road trips along with CO2, otherwise your phoning roadside assistance. Your dealer will have them specific for motorcycles (size wise) and fancy mushroom type plug kits, if you shop around you'll save a few bucks. Any plug kit does essentially the same thing when used properly.
On my vehicles Ive put thousands of KM on plugged tires, it will affect balance to a degree and if improperly plugged it could push out/leak. On a vehicle its not as concerning as the balance wont be noticeable and you usually have a spare if the plug fails, and 3 more tires to keep you upright. On a motorcycle if the plug fails it could spell trouble fast.
But, if done properly a plug can last the life of the tire with no ill side effects. At this point its my excuse to put better rubber on the R3
