... #3 injector is clogged up and the others are in bad shape too. Here is another reason you want to eliminate compression first. A ring could stick in its groove by sitting too long. A valve being open will cause rust by the condensation creeping in. This will cause a chemical reaction to begin to deteriorate the metals to dust. So this is more or less how a ring will lock and not create the compression that needs to float in that ring groove, move out and press against the cylinder under compression. If this scenario is part of the sitting process, this too will lower compression to a fouling point.
So chasing your tail by not checking compression first: eliminates the injector. See how simple a compression will tell a whole lot of things? Saves lots of money like: throwing parts at it like the stick coil.
Try any quality fuel injector cleaner, so buy the gas stations cleaner in a can. Chevron/Shell/Exxon-Mobil. Read the proportions needed per liter. Keep riding till it cleans itself, meaning, keep adding cleaner every tank fill till it cleans up. No need to swap injectors because sitting is a killer, if you do not dry that injector out, or clean it with a cleaner only [and park it dry for years], here is your sitting scenario.
That means you'd have to have a remote battery to spray the injector so you could feed the cleaner at the back of the body itself. Electrically, you just want the plunger to open so the cleaner washes out the gas, evaporates and is clean of fuel: to varnish while sitting. And one spark exposed you go messing with that chemical, well, you figure out the what happens next. You are seeing the results of a bike sitting with fuel in it. 1 year is pretty bad. 2 years, I don't know, short of sending the injectors out to have them cleaned with an industrial chemical you can't buy in a can.
Maybe you'll get lucky.
