1 Can't start a bike that has been off the road a while - any suggestions? Wed Apr 27, 2016 5:41 pm

Bought a 1983 K100 that has been sitting idle for a few years. Here is what we have done so far:
I changed the oil and oil filter, drained the gas out of the tank, put in a new fuel filter, and put in a new Odyssey battery. The bike would turn over but it would not start. I can hear the fuel pump whirring loudly. A few times it could 'chug' once as if it was about to start but it didn't.
Then we changed the spark plugs but still nothing. We checked they were sparking and they were wet so it is getting fuel. We then took out the injectors and gave them a good clean. We cranked it when they were out to verify they were spraying ok. Putting everything back together - and then when we try to start it - it usually 'chugs' the first two but not much after that.
Today I did a few things like cleaning the ground and connections with electrical contact cleaner. Then we tried starting it while spraying "Easy Start" in the air box - and she fired right up. However then she died a few seconds later. We managed to do this a few times but it would not keep running. Once we heard a big of a bang and some smoke rose from the engine, not sure why.
Tried many times more, at one stage I was able to get it running without the Easy Start, on what seemed like incredibly low revs, it turned over for good few seconds just gurgling slowly, but then it would cut out.
So I'm guessing a fuel problem. Can anyone give me some pointers? Thanks
