First time poster and new to this site.
I have a 2007 ultra with 19,000 miles on it. Engine is a 103 and I run Syn3 in the engine, primary and transmission. I have done all the recommended services at the right intervals.
The bike has run perfectly for nearly 19,000 miles and the tranny has been really good and quiet in general. Just short of rolling 19K I noticed a loud noise coming in 5th gear.
The noise is not constant. When riding (cold or hot) and first shifting into 5th gear, the trans is quiet. After about 5-8 miles of driving in 5th, the tranny starts to make a really loud howling/screaming noise and a fair amount of high frequency vibration starts to develop. Shifting out of 5th resolves the problem. If I wait a few minutes and shift back into 5th, the tranny is quiet again, for a few miles and then the noise comes back.
I think this might be an indication of a bearing going out. I have a good 1 1/2 months of riding yet that I could do, but am debating if I should keep riding and wait until winter to take it in, or call it done and get the bike in now.
I don't think this is the usual 5th gear noise issue. I suppose that would have popped up sooner and that noise would be more constant.
Any thoughts or suggestions? Maybe a fluid change to something other than Syn3. Seems that most people are recommending on not using Syn3 anyways. I have not drained the tranny yet to look for any metal flakes but I suppose I could do it and take a look.
Thanks for any thoughts you guys may have.
