Broken Timing chain?
So the bike won't start. ('89 3AJ Tenere) This wasn't too much of a worry until I scared myself with a huge backfire when cranking it over. Then, thinking back to how the starter motor didn't seem to be having to work as hard as normal, I have come to the conclusion that the timing chain has snapped. It's either that or there's a valve stuck upon, right?
So, while I ponder whether I'm going to brave the bottom end and do it myself, a couple of questions for the assembled knowledge:
Is the XT600 engine an interference engine, and if so will being cranked a load of times with a snapped chain have damaged the piston/valves?
Are there any other jobs I'd be as well doing while I do the timing chain?
