I changed the oil yesterday. Since I’ve changed gauges twice, I am guestimating I was maybe a couple hundred over 1000 miles since I replaced both filters and changed the oil the first time. Checked my new sump filter; not blown out, so that’s great. There were small metal shavings on both the magnets on the filter. No big chunks of anything. The oil was pretty dark, and I hate to say it but it was pretty metallic. It reminded me of the silver iridescent slime I got with the terminator toys when I was a kid in the 90’s that was supposed to be T-1000. Is this “normal”? How worried should I be? One thing I feel is worth noting; I bought “THE XS650 ENGINE including the electrical system” book from amazon, and the author explains that the electric start was added to the engine later and causes considerable damage. He recommends using it as little as possible. I have followed this recommendation and have stopped using it to actually start the bike, except for the occasional starting in the street if it dies while idling in the first few minutes of warming up. (That’s always embarrssing. It’s only happened to me a few times) I have checked my cam chain tensioner several times after changing the oil back in april. The protruding “button” of the plunger is where it should be; just flush with the cap, and I can feel and see it pulsating with the engine running. Also, as I understand it, if my cam chain was loose my timing would be a little off, and I can usually get it to cold start the second or third kick, sometimes the first. She idles and runs fine; I’ve just been riding and wiping her down all may, june and july. I recieved my Pamco Saturday, so when I have a good 5 hour chunk of time I’ll replace those leaking cam seals and get the ignition installed, and use my new timing light to set the timing. Part of why I haven't Bothered checking timing or anything else is because she runs fine, and I’ve known I’m going to be tearing into it for this, so I figured I’d just wait. OH! Also, I’ve adjusted my rear wheel once already with that new chain, around June 11th, and I noticed this weekend it’s time to adjust it again. How often/how many times/how many miles do you normally have to adjust for chain stretch?
