My 2016 TBA LT has developed a “rattle” that seems to be coming from the front sprocket at exactly 65 mph in 4th gear. Once I shift into 5th, noise goes away. Very annoying, so I bought a new o-ring chain although the bike only has 8,000 on it. Inspected the front sprocket for anything unusual but didn’t see anything that would cause a “rattle”. Installed the new chain per the book, and the noise did go away for the first 50 miles or so, with the new chain, but then came back. I put the bike on my jack and put it in 4th gear, and sure enough at 65 mph indicated, it rattles quite significantly from the sprocket.
Any ideas? Anyone else have this issue? Thanks in advance..
