I was hoping I would not have to post this but I don't think time is on my side right now.
I am planning on meeting up with @Blueflame in 2 or 3 weeks. So about an 1200 mile ride. We are supposed to get rain for another 4 days. So loose more time there.
Here is the deal. I had my bike down for close to 3 month for misc. stuff.
I removed the stock fuel filter and replaced it with a 3/8 hard line. I added a glass filter below the petcock valve.
I put on a new to me rear wheel. I changed out one bearing. The other was good. I put in my rubber pads and also my final drive gear.
Here is my issue. My bike runs great.
The motor is pretty quiet up till about 55 mph. At that point. If I am on the throttle
at all. I start to hear a gear whine as well as a rattle in the engine or in the exhaust? The sound seems to be coming from the right side of the bike from what I can tell.
I can gear what sounds like gears whining along with a rattle that sounds like marbles shaken in an aluminum container. If you have ever heard what car main bearings sound like when they go bad. It is very similar to that.
This does not seem to be rpm related. I can run the bike up to 60 and not hear the rattle. Once I am in 4th or 5th gear you can hear it. At a constant speed, the noise does not seem to be present.
I had a half tank of gas when I parked the bike.
3/8 I put in a gallon of gas and rode about 50 miles.
3/10 I filled the bike and added 4oz of seafoam
3/11 Rode the bike about 50 miles
3/13 I rode the bike about 60 miles, I don't remember if I heard any rattling here. 3/18 I changed the oil Rotella T5 + K&N filter --- I was running Rotella T6 & honda filter before. The bike had a K&N 303 filter when I bought the bike.
3/19 Put in 2 gallons of chevron premium. I rode another 60 miles - I can hear the rattling good.
I tried to record the noise. The wind noise at 55 makes hearing the rattle and gear noise in my camera a little hard.
I have been thinking about this so much that I am not sure of some details. I only put down here what I am sure of.
I have short videos for sound showing the bikes sounds good through 3rd gear in town as well as the videos of where the noise should be heard at 55.
With head phones and the volume turned up. I can hear the noise in the video. As a rider on the bike. It is pretty annoying.
If any one has any ideas what I could check. It would be great. I am starting a list of things to check once the weather permits. If it only sprinkles now and then. I will pull the cover off the bike and start looking into things sooner. I will just plan a day to clean the bike up before my trip. Which I hope I will be taking.
