Hi guys, new to the forum and boy do I need you experts on here to help me
I recently bought my wife a 2007 Shadow Spirit 750 and it was owned by a friend of ours. It only has 7900 miles on it and is really clean. My wife has only been putting around our massive subdivision on it until she gets comfortable enough to ride on the roads with me. She took a riding course and got her license but is slowly building confidence to out amongst the crazies, lol.
Recently she took off on it and rode around the subdivision for maybe 10 minutes or so and came back and told me the oil light had come on and she had noticed a "sound" that she didn't think the bike was making before. She asked me to ride it down the road and I did. I didn't go far, got it up to about 40 mph and the oil light never came on for me but I did notice the engine was making a ticking/tapping noise that I had not noticed before.
I brought it back into the garage and parked it. It was due for an oil change so I changed the oil and filter on it this past Saturday and the tapping seemed to be louder but maybe it's because it's in the garage and sounds louder. I noticed that it doesn't idle smooth either, I can see it shaking the tank and it seems cold natured. I rode it down my street, again got it up to about 40mph and it seems to run fine but when I brought it back in the garage, it's still making racket. If I start it cold, it runs and throttle response is poor and and it'll cut off.
I don't have the foggiest of ideas what it could be. My brother at first thought it might be fuel related, maybe ethanol rearing it's ugly head but I don't see how that would make a tapping noise. Well, upon further investigation, I recorded it running with my phone and it appears that the racket is coming from the front head. I had originally thought it was coming from the crankcase because I could feel it there but I can also feel it in the fins of the head. I then began to wonder if it was an exhaust leak. My brother, strangely enough, called me and said he (after seeing the video) thinks it's an exhaust leak at the header. I noticed that the left bolt seemed loose but upon tightening it it seemed to make zero difference.
As for the connection, I see a split piece of metal that seems to act as a press that's using the flange to press against and I guess it's purpose is to keep the exhaust gasket in place. Am I close at least? Does anyone think it's the exhaust? Or is there something more sinister at work here?
I can't get a good look at the rear exhaust to see how it compares to the front header connection but these are pics I took of the front.
I don't know anything about troubleshooting these things so any help is greatly appreciated!!!
