Hi!
I have a problem with my K100 that started with a bad Hall sensor. When searching for that fault I also found bad fuelpump (changed) and had to change rubber and filter in tank. I also changed one coil, some rubber parts to avoid vacum leaks, and o rings on injectors. Checked connector under tank, should be ok.
Still i have problem with the bike. It works great the first 30 seconds but after that it doesnt run well. All 4 Spark plugs are black. When cold down it works fine again for another 30 seconds.
What can I do next? The weather here in Finland is great and of course bike is broken...![Sad](https://2img.net/i/fa/i/smiles/icon_sad.gif)
