Hey everyone. Recently got myself and old '98 XJ900 with about 137k which needs a little TLC. First things first, there's a knock at idle in the engine. Sounds like it's coming from whatever chain turns the alternator. No idea what that is as I don't have a manual as yet. The knock is more pronounced when cold, but is still there when hot. I've used a makeshift stethoscope ( twistable screwdriver ) to have a listen. Sound comes right up and through the alternator. I took the alternator out and everything seemed nice and tight. I've seen people make reference to a starter chain which could be the one... It's in the general vicinity, and it would make sense to have one chain for the alternator and starter. But then again, I just don't know. Otherwise the thing seems to run alright, sounds nice all through the rev range. Anyway, point of this post is trying to find a reputable shop happy to take a look. I've given Everything Two Wheels a call, and they're not really interested in taking on the job (due to age + miles). I've called Intyre too, but their engine mechanic is going on leave for a while. I'm not overly keen on speaking to City Yamaha as I've had issues with em before. Anyone want to name a place or have any suggestions on where I can take it? I'd prefer not to work on it myself as I just don't have room, so it'd be a right PITA.
