Long time lurker, first time poster. Looking for some advice, so I figured I'd try my luck on the boards.
Early last week, my '05 Kawi 650R suffered some kind of major mechanical issue. I was riding down the highway under moderate acceleration when I heard was 3 or 4 loud *BANG*s followed by a significant loss of power. The motor sounded somewhat normal, as I came off the throttle and pulled off the highway, but it died as soon as the revs dropped below 1500. Attempting to start the bike resulted in a horrible gut-wrenching 'clunking' sound, as if something was shaking around inside. Needless to say, it wouldn't start, and I dare not try any further.
A few days later, I drained the oil, pulled off the airbox, and yanked the plugs. There didn't appear to be any glaring issues with the used oil as it drained, but the airbox was littered with small metal shavings. Looks very much like bits of aluminum, but I can't be sure. Running a finger around the inside of one air intake yielded even more small metal filings. However, the plugs didn't have any sign of these filings.
Clearly, not a good sign. While I've got nothing against paying the pros for proper service, I'm more than a little hesitant to drop more cash on this bike without having more information. Especially since I've had some feedback saying this could mean the rod has snapped / the entire motor is scrap.
I'm hoping for any kind of feedback indicating what metal shavings in the airbox might mean (I know thats a vague question, but i gotta try ) Is there anything else I could try before taking it into the shop, to get a better idea of whats wrong?
As more of a side note, How in-depth can/should the average owner, before handing over to the pros to tell me whats wrong? Like I said before, I hate the idea of dishing out more cash, just to have someone tell me its scrap.
