My B5 just started making some horrible noise. I was hoping some of you wiser enthusiasts may have some suggestions.
I've never had a problem like this before. Rode my B5 to work yesterday; about a 20 mile commute at speeds up to 70mph. No noise then. When I got on my bike for the commute home, it started making this medium pitched vibratory noise at high RPMs. I thought it might be the headlight assembly (I've had some minor rattling before) so I headed home with the annoying noise, but no loss of power or other problem.
Today I changed my oil, lubed my cables, greased my pivot points, and took of the headlight assembly to find the problem. Needless to say, it wasn't the headlight. Once I was off the bike and sans helmet, it sounded like was coming from the engine.
The B5 starts without difficulty and sounds just like it always did during idle and low RPMs. When I get the RPMs up in any gear, that's when the noise starts kicking in.
Here's a video with me revving 3 times in neutral:
